Sooo 400.00 dollars without losing any weight, classifies as pretty much the same thing I would think.He's got slip-on cans, not a full exhaust.
The "AirHawk" has a Muzzy slip-on system (can and Y-pipe) that was on the bike when I bought it, and the airbox has been modified and the carbs re-jetted.
When I got the bike back in the '90s, it was loud as F*ck. No, I mean F*cking LOUD AS F*CK!!!!
A bit of work with ceramic-wool and some stainless bits and pieces quieted it down about 20db - depending on how hard I nail it, I catch 89-92db @ 25' with the meter perpendicular to the bike.
Damn-near 88db-driveby "legal".
I agree that stock headers are a great design, and that it is hard to beat the development thats put into them. Thats why its so expensive for the aftermarket, they have to spend alot of time in R&D. I also agree that suspension affords more gains as well.Er, it was on it when I bought it. A Yoshi RS3. Too ****in' loud so I put on the stock can which made it run much better. The Yoshi pipe caused a serious lean running issue in the midrange. I put a Holeshot jet kit in it and remounted the Yoshi when I decided to sell it. The jetkit solved the lean issue and the Yoshi attracts the fanboys.
MC-USA did the whole aftermarket exhaust experiment on the ZRX also and came up with very little HP gain. Apparently the stock header flows pretty well.
Put on an aftermarket can or system and don't rejust or remap and you are looking at trouble.
Hey, but if people think it's worth $1000 to save 15lbs and get 2 more hp, which is within dyno error, then go for it! Myself I recommend that people get some training and upgrade their suspensions before blowing big $ on something that is likely to give little gain. I figure the exhausts are the least bang for the buck.
Not that it's going to matter in a few years when the laws become too draconian and everyone remains (and returns to) stock.
