I've heard the Cobra pipes but not the TBRs. I personally like the glasspack mod better. Deeper & throatier sound. MarkT is reportedly the best in the business for doing the mod and with his deal you retain your stock Honda headers which don't turn colors.

I had glasspacks done locally with help from instructions here on the site and everybody says that's the way this bike SHOULD sound.

I think you should strongly consider MarkT's pipes.

That sound you are looking for may not come from TBR or Cobra. I am not the biggest fan of the sound from either. I looked and listened to other Valks and the winner in my book was a modification. Price was a concern and the idea of tinkering was a plus. Big truck stacks using either glass packs or gutted mufflers is a sound you might be wanting. The rumble is low and pleasant to hear. Idle is that of a V8 and around 3-4K RPM people will move out of your way. Good Luck, it took me almost two years to decide.

If you want the "deep rumble" sound get a chance and check out both Two Brother 6 into 2 Slashcuts or the Glasspack mod from Mark T. Both sound very good and look very good. I have the TB and the headers do turn golden (all stainless steel) the Mark T's use stock headers so no color change. Check them ALL out and make decision for yourself...... GL

In Reply to: Cobra vs. TBR posted by Brett on Tue - Nov 21 - 9:11pm:

My understanding is that Cobra has baffles that are removeable. TBR are in for the count. Both will probably lose you a couple of horsees unless you rejet the carbs. Both will eventually turn blue and/or gold at the header. Both have wav files at the respective company sites to "hear" them. Better yet, try to find a member that lives close and listen to'm. I nearly went w/ the TBR 6 into 6. I love the look and sound.  Seemed a little loud for all the time riding and also a little pricey.

Me? I went w/ Mark T.'s glasspack n' trombone set. Very pleased! Price is very reasonable for the  mechanically challenged. You will also get the added benefit of adjustable sound. Loud when the mood stikes but "relatively" quiet for all the other times. Stock look is a trade off. Sometimes I wish for that 6X6 look. I'll keep what I've got thx, and would do it again! BTW. Mark T. is AAA#1+ to deal with. That alone is worth a bunch to me.

My advise? Drill back baffles while you're deciding.

Chet has the Trapps and loves them, because of the length, your gonna have then stopping 1/2 down the bag.  You'll get some heat there. Also look odd, but beauty is in the eyes of the beholder.  Trapps are tunable, so it should reduce the noise.

Have you considered the Mark T Glass packs. Sound real good, mellow deep rumble (no inserts), unless you goose it, then sound great. I use mine with the bones (inserts) in (loud), except for long trips, and really like them. Thay also increase perrformance, and when used with a trigger wheel and K&N filter, move the lady along nicely, and on the highway, get almost 40 mpg (unless I'm playing, of course).

Trapps will definetly wake the I/S up.  BUT, you got to build a protection shield for the bottom of the bags.   I have a Tourer that I ran Trapps on for several months.  I burnt a hole in one of the saddlebags from the heat.

I now run the glass pak mod with 4" truck stacks turned down.

There used to be a picture of my setup on the picture page. Search 'Bullard' and that is my Green/Cream unit that comes up.




Set your wife up with Mark T.  

Posted by Jim Caldwell on Fri - Dec 1 - 08:54am:

I gave my wife some catalogs and stuff, including the info from Mark T's web site as possible suggestions for my birthday present (you know what I really wanted.)  My wife didn't know glass packs from ice packs. Anyway, she called Mark and Emailed, he completely sweet-talked her.

"He'll think of you every time he starts up."  (Normally we guys save that kind of stuff for when we're really in trouble).   By the time he was through, he had her wanting the pipes more than I did (if that's possible).

Anyway, got my pipes on Nov. 29, played hooky from work on the 30th to install and of course test ride, and WOW! Great sound and more power.

I even thought of my wife when I started up.

This is now a proven technique, USE IT!

Just put my pipes back on Friday after receiving them back from Mark-T. No, you don't need to put the Valk on a can be done on the kickstand. The right side is easy, just line up the bolt holes and put tighten the nuts up. Watch your torque. The left side is harder, but not bad. Take your time and tighten all bolts to specified torque. If you have a "kick shifter", be cafeful when you put it back on. I torqued the main bolt right off and had to get a replacement. Put all chrome on first, then re-install the pipes. You will have to loosen the bolts that hold the rear foot pegs so the two bolts on the pipes are easier to line up.

Enjoy the pipes. I do. They are the best sound I've ever heard.

Alien, all you do is drop your stock pipes off the valk, take the chrome heat shields off and the tip, box em' up and ship them to Mark-T in Franktown, Colorado. He'll install glasspacks and send you a set of pipes inserts (called trombones for louder rumble), and ship them back. Way great sound and you get to keep the stock pipes and stock chrome that came on your bike. And, no re-jetting, no nothing. Go to

Lee it can be done on the side stand, but a lift makes it easier when you work on the kickstand side. One note, when taking them off be careful that they dont bang aganst the floor. Its not hard to dent or damage them.I have had mine on and off several times and reused the manifold gaskets every time with no leaks. Be careful when tightning the manifold bolts as they are not hard to twist off. Over all pretty simple to do. Good luck and you will love the glasspacks...TB

No difference...

Posted by MarkT on Sat - Dec 16 - 01:10am:

In Reply to: EXAUST MOD. MARK TOBIAS posted by RED DRAGON on Fri - Dec 15 - 6:21pm:

I'm assuming you are asking which makes more power, the glasspacks alone or the glasspacks with the Mild2WILD TromBone inserted. (FYI, the TromBones bypass selective inches of the glasspacks, THROUGH the glasspacks, allowing the rider to effectively select the active length of his glasspacks, thereby tuning the sound from glasspacks to straight pipes, and everything in between.) The TromBones have no effect on backpressure or the exhaust configuration, all they do is prevent or allow the sound waves to be absorbed through the holes in the sidewall of the packs. So theoretically there should be no difference in power between having the bones in or out.

This has been tested and proven by SoonerDynoman who has tested several of my customer's pipes with the bones in & out, and could find no predictable difference in performance. Specifically, some bikes had 1 more pony with them in, and some had 1 more with them out. Insignificant difference.

You may be interested in Mark T's Mild to Wild Glasspacks. They sound awesome and you won't have blue  headers like all of the other aftermarket pipes around. Many people on here have them and I haven't heard a bad thing about them yet.

In Reply to: as an afterthought...why Mark-Ts? posted by Socrates on Thu - Dec 21 - 2:50pm:

I never considered the TBR pipes whatsoever. Not that they aren't a good product, I just knew I wanted the glasspacks. I had seen and heard them on other Valks, and that was all it took.
Here are some of the benefits I see of choosing the glasspacks.
        1-Won't turn blue like almost all other pipes will.
        2-The sound. I have heard most, if not all of the aftermarket choices. I liked the TBR 6-2, the Supertrapps,
        and MarkTs. The TBR are too pricey for me(and they turn golden), and I don't care for the look of the
        Supertrapp. Just personal preference though.
        3-Exhaust note is adjustable to your personal preference if you purchase the Trombones
        4-MarkT's pipes add horsepower. Many aftermarket pipes don't add any, and some take HP away.

In Reply to: JeffL and/or Torch1972-Tell me! Tell me! posted by Socrates on Thu - Dec 21 - 2:24pm:

No carb work required whatsoever in my case. The trombones just slide in and lock into place inside the glasspack. I have the longer truck stacks, so it is a little more difficult to remove the bones, but I'm sure with a little practice and some welding gloves it will become easier. The sound is awesome in my opinion, if I hadn't just put the bike up for the winter last week, I would call you and let you hear the awesome sound over the phone. But, I know MarkT would do the same for you if you called him.

The only other thing I can suggest is to do the truck stacks. They look awesome, and I think they give the glasspacks a slightly deeper tone as well.





Thanks JeffL, Torch1972, AND Mark-T :)

the 2 main reasons that I got MarkTs was #1;pipes wont turn technicolor,#2;I like loud,wife doesnt.This setup has the easiest/quickest method of changing the sound.The only way you can tell that you have the bones in is kneeling down and looking inside the pipes.When I went to Sturgis I left the bones in all the time uncut and had a bunch Of Harley riders telling me it sounds damn good.Also you can cut the bones to your own personal liking.Sounds like a Porsche on steroids,with the bones out has a deeper sound(wife can live with it).So far I didnt have to rejet,have K&N,6 deg trigger wheel and polished the intakes.Bike runs great.




Mark T's Glasspacks are best served cold

Posted by Kruzer on Sun - Dec 31 - 10:53am:

I have found this out since winter has put me back in my fullface helmet. Man o man those packs sound much better w/ no wind noise.

I have started playing a juvenile, but quite fun game w/ these pipes. It works like clockwork. There are several Honda dealers close by that I frequent. Everytime I see an employee that 'doesn't know', outside as I approach, or better yet, as I fire up the Lady to leave; I'll blip the throttle a couple of times. It looks normal to them but they invariably nearly break their necks in a double-take...

Anyway. Thanks again Mark T. That xtra rumble I hear now is great! Still just as pleased as that first day. Maybe more so..

I've had MarkT's glasspacks for a couple of years now. There is no one on the planet that makes a better product than Mark. You can do it yourself, but Mark does the job correctly. I used my stocker main chrome shield and added Air Flow 18" slash cut (4 inch ID with a cut and a hole for expansion) to couple up with Marks packs. Sound is terrific and everyone is pleased with the sound...

That's what I'd do. BAGGER

if you're like me. I went through all the steps, rode it awhile with each, always needed more. Finally sent my pipes off to MarkT, he did his magic, WOW that's what I was looking for. Especially the Trombone tunable idea, how cool now I can be rowdy or quiet for mama. Just put on Truck stacks, looks WAY cool and improved the sound even more, didn't think that was possible but now the sound is deeper in tone, a bit more volume, and farther back so mama likes it. Now Mark is doing the stacks too.

Send em off to Mark, you'll save a lot of steps and it's a good time with the snow...

john galt,

First off make sure that you get a few bucks from the guy you are swapping with since the 2bros pipes retail over $700 and the stockers sell for $300. It's hard to say what you should do with the carb settings. If it was rejetted it would depend on how it is set up. Check the plugs to see what the color is. If they are really dark or wet then it is too rich. If they are a tan color it is just right. If you get money in the exchaneg I would go for the MarkT's glasspacks.

Tom, I had my mind made up to get the 6X6 Cobras when I first heard them. Then, I checked around and was told I'd have to re-jet the bike. Well, needless to say that didn't make me smile knowing I'd have to spend another 125 or dollars. Much less, I looked at another Valk with the 6X6 on and guess what, bluing.

I went to Biketoberfest last year and met up with other VRCC members for breakfast. Several had the Mark-T modification. I asked them to crank em up and what a difference. I immediately decided on the Mark-T pipes.

I got home, took my pipes off, boxed them up and shipped them to Mark. They were sent back just under 2 weeks.  When I put them on, what a MAJOR difference. Everything eveyone says about Mark-T pipes are right. They sound fantastic, the bike performs better now, much quicker after you twist the throttle, and I have a permanent smile listening to the pipes growl.

IMHO - go with Mark-T. He'll do ya' right. You won't be sorry.

How can I put this diplomaticly? I know; "they suck". You will loose HP. You will loose MPG. You will loose torque.  When everyone accelerates you will be last. You will loose top end speed. You "friends" will turn on you and laugh when eveyone Dynos their bike and you come about 8 HP less after spending $$$$. Then, you have to buy them beer and listen to their stupid jokes. :o) I highly recomend Mark T's 'Mild 2 Wild' system. You can tune it for whatever sound you prefer, and you will gain HP. If you are still set on putting them (cobras) on, you can probably find several good used sets in the classified at about 1/2 price. For a new set, Hal is da man.
