i have a cotton's 3" single exhaust that came on my car. i never had a problem with it rubbing the driveshaft, but here the past couple of months under hard braking it rubs. LIKE AT THE TRACK, it's embarassing. i had the guy at the ticket booth ( after the return road ) tell me to fix it before i go back out 4 times once. it's loud as h..e...double hockey sticks too. now it's worse, i went over a train track the other morning and it did it lightly, i brake moderately now and it wants to rub. i have two rings on my driveshaft now. one from the muffler and the other from an exhaust clamp that hold the muffler on. what gives? is anyone else having this problem? does anyone have a solution? is it my suspension? oh, with 26" slicks on it it's worse, or any taller tire. the nitto's make the car do it, but the slicks made it worse at the track.
the dam pipe is partly under the driveshaft, are they supposed to be there.
