O/T exhaust question

[mwdbruno]

I have a buddy who has an 86 Kawa 900.  He is new to riding and bikes in general and I've started helping him out with mods.  He ran across a Kerker exhaust system for his bike and I am wondering if anyone has had any experience with these exhausts.
Any info would be great!

Thanks!!

My experiences with Kerkers have been nothing but good. They made in the '80's the best aftermarket streetpipes that made decent usable power without alerting the cops with too much noise (Yoshimura). And they were best on the Kawasaki's. I think because they did most of their research on Kawi's.
