Ok, I just got the apexi ws 2 exhaust put on and I'm very happy with the exhaust minus 1 thing. Anytime rpm's fall below say 1500 between gears, it sounds like the diffuser is vibrating against the car, has anyone else experienced this with this or any other exhaust.

thanks

 

hrmm... we have installed a couple of these... havent seen clearance problems...

try to have almost an inch around the mid pipe and the rear cross brace...

if you dont have that much space there you should put some spacer shims between it...
