[SOS]

Looks nice to me but I took my can off just to see what it sounded like and it souded like I needed to tweak something if I was going to ride it like that. Loud as hell though.

[GSXFred22]

Well it is louder then the Yosh but the pipe is about a foot long and about 8 inches of it is baffled plus somehow the endcap helped with the noise too. It doesn't sound like there's anything wrong with it. Just sounds the same but louder.

Looks good to me and saves a bunch of $. I'm thinking it would be too loud for my tastes but I'm impressed with the barn door engineering. good job

[GSXFred22]

Thanks. I really like the sound but it is a little loud in town. I was thinkin of having a baffled cone tacked in the endcap. Anybody think it will help? It doesn't perform any worse or better with the short pipe. Will I lose anything with this idea?

I liked the way the cut pipe sounded jus not in town so i put my ss2r back on...also my bike is yellow so i painted my shorty black with some hi temp paint

[GSXFred22]

Yeah I switch back n forth between the shorty and the yosh. If I'm riding myself or with other quiet bikes I run the yosh. I've been riding alot lately with at least 10 bikes and most of them have GP pipes and are pretty loud themselves. I do wish I could find a shorty muffler to mount to end of my pipe though.

Hi,
Tuning is recommended for best performance, but is not required. Many of our customers do not tune their motorcycle after installing our exhaust with no problems.
It is a misconception that low backpressure causes damage to engine valves. Harleys run straight pipes all day with no problems. Without tuning, horsepower is increased only at full throttle and torque is decreased during normal riding. If tuning is done, both horsepower and toque are increased.
All of our exhausts come with a 100% satisfaction guarantee. We accept returns with no questions asked. Please let us know if you have any other question or concerns.

does this sound right? I'm a noob, how would i go about tuning it? is it carb synching and adjusting or is there more to it?

The biggest misconception I hear about exhaust changes from multiple bike forums is that you have to either re-jet for carbed bikes or get a Power Commander\TFI or something for FI bikes.

For the FI bikes you can bolt on an exhaust and go. It wont increase performance. Your bike is already restricted in the amount of air it can take in. For an FI bike, unless you are modifying the intake you do not need to do anything other than bolt on the new exhaust and replace the gaskets. Like I said, you wont get a performace gain, just a different sound. If you change the intake you need a Power Comander\TFI or something.

The bottom lne is "You cant put more air out of the back of the bike than is coming in"

The bottom line is "You can't send more air out of the back of the bike than is coming in".

Carbed bikes are pretty much the same, but you may need to adjust the air\fuel mixture some. Thats just a turn of a screw. On multiple carbed bikes, like the Kat, it just takes a few times to get them all set right. the trick is all 4 carbs have to be right. If you change the intake, you will need to rejet because you are bringing in more air.

Incorrect. The ECU will compensate slightly, several high performance slip ons have proven power gains without remapping the ECU. Muzzy's, Micron, Akra etc...

Not much, but it is there. Now an aftermarket filter and a full exhaust...

[usmckatana]

i like the homemade shorty...gives me an idea...hmmmmmmm...

[VooDooRacing27]

Or you can just take your yoshi and cut it down about 6". I did that and my god what a difference in sound!! It sounds alot deeper and more throaty, and is still legal. Gives you the best of both worlds, nice sound, great looks, and it dosent hurt the performance. I can put pics up if anybody would like to see.

[BadLuck]

The ones in my head. Guess I didnt word that correctly, which happens from time to time.

You may need to turn out your jets some, thus turning them. Maybe not a few turns, but add is slight bit of fuel. The key word is may need to.
