Those mufflers are for cars. Probably too big and there's no easy way to mount them to a bike. I doubt they would cause damage but I'm sure you would suffer a power loss if you managed to kludge a set on to your bike some how. Even the TB pipes were shown to cause a slight power loss on the dyno if no other changes were made to the bike.

Thanx for your help just lookin for a cheaper way to get alittle more noise

Wendy:

The Two Brothers exhaust is really loud and booming. (It won't really bother your jetting, but you might consider rejetting at some point anyway.) The vast majority of ST1100 owners who have tried the Two Brothers exhaust end up getting rid of them after a short time. Not only are they hard on your ears, but if you carry a passenger, they'll end up hating you in a very short period of time.

The Staintune from Austrailia are supposed to be real nice, but I've not heard them. And they're even more expensive than Two Brothers.

Finally, you might not want to hear this, but noisy motorcycles is probably the number one complaint non-motorcyclists have about bikes. And this very complaint is what keeps the AMA busy fighting motorcycle bans all over the United States. In my humble opinion:

It doesn't have to be loud to sound good.
Loud pipes do not save lives.
Loud pipes cause motorcyclists more problems than they realize.

And keep in mind that this comes from a certified motor junkie who thinks that the most amazing sound he's ever heard was standing 3 feet behind the 6 cylinder Honda GP bike from the early 60's as it was being warmed up at Laguna Seca. Awesome!

Cheers!

Exactly, Keep the ST as quite as posible, nothing is more irritating than a loud bike. (race bikes exempt)If you want more noise put on some loud horns, just ask and I am sure you will get lots of suggestions on which ones and where to mount them.

Ditto to the above threads about noise, keep it quiet, your friends, neighbors, and your ears will appreciate it in the long run.

I think everybody may be overdoing what they think of as louder. I DON'T want straight pipes either, but something just a little throatier, so it doesn't sound like an angry sewing machine.

I agree- I too would like to hear the exhaust at least a little bit, and not just the blender or sewing machine powering my ST. I love the bike, but I always hear talk about how great the v4 sounds ( :shrug1: ) I've never heard it. Wal, who is a member here and runs the v4hondabbs site used to have an ST1100 with a custom exhaust with Supertrapp cans on it- all who heard it said it was the best sounding bike they have heard. Maybe he can chime in here and let us know what he did. Wal?

Hey Duke ;-)

I tried the D&D pipes and I tried the 2Bros. pipes :no1:

There are few things worse then an ST with open pipes like the D&D or the 2Bros. The sound is just an awful noise. It was louder, but the tonal quality was just this raucus messy noise that hurt your ears by its sound and not totally by its Db.

Since the OEM was way too quiet IMHO, I decided to take a big gamble. I bought the 2 Bros midpipes from the spare parts listing in parts411.com . In hindsight, I think the D&D midpipes would have worked better because they were a hair longer. Then, I bought two 19" long internal-core Supertrapp universal fit stainless steel mufflers from Dennis Kirk. These do NOT look or sound like the old exposed diffuser disc looking 'Trapps that we've all seen in the past. They look like a brushed stainless steel sportbike can with a normal sportbike looking nozzle on the end cap. The tuning discs are hiding inside. I used all of the supplied discs - I think 8 in each side - and the closed end cap. I also bought some Seal-Clamps to make a great clamp from the midpipes to the Y'pipe on the OEM exhaust (not mandatory but I like them).

The result was the sweetest sounding music that I've ever heard from any ST!!!! It was the best sounding bike I think I've ever had. At idle, there was a little rumble but not much. On the highway at 75-90mph they were a hair louder then stock but not too much, and certainly not annoying to your ears after 1000mi in a day even. But, when you gave it throttle it had a deep wonderful sound that let you know that this wasn't your father's ST. It was still muted because the Trapps have a baffle in them, so it wasn't obnoxious like the other "through-core" designs (2B + D&D) but not as corked up as stock with those discs inside opening them up for more flow. I sold them after the bike was totaled and the new owner is thrilled with them too. The 19" is the right size for balance of sound I think, and I wouldn't use the shorter or longer ones they sell.

As far as jetting goes, I can't really help much. I opened up my intake as well, and did some custom jetting of the needle taper, slow jets, and main jets. When I got it "right" I went to a dyno and fine tuned. Based on my experimentation with the intake, I can say that IMO if you don't cut open the intake, you won't need to rejet. The intake is so restrictive that you'd almost need straight pipes and a shop vac to pull enough air through the bike to need a rejet, hehe.

The downside... it ain't cheap. But, that depends on your definition of expensive... it was still cheaper then those Staintune pipes. Bette sounding then the staintunes I've heard. A $hitload better looking IMO too.

Thanks for the info, Wal. Guess I'll start saving my $$. BTW, met a guy the other day on a newer gen. Magna- that was a sweet sounding v4. Wish the ST sounded like that.

[naturally wired]

Bought the staintunes for my 1300 you can listen to them if you get to the right web site on the 1300 they also have removable baffles so you can tone them down a little if you want they cost $700 a pair and Im pretty sure you can get them for your 1100 they are top shelf, beautifull finish , plus they bolt on just like factory pipes... the best $700 I have ever spent :cool: please pm me if you have any other questions
