Exhaust Question?

quiksilver225 · May 28th, 2008, 08:04 PM

Changed my entire exhaust in the winter to BBK longtubes, BBK catted X-pipe, and SLP loudmouth kit(clamped) and ever since it has creaked when the car bounces or take a bump. Maybe a hanger, but i doubt it. Wierd thing is that it doesnt start creaking till the car has warmed up... It almost sounds like there should be a gasket somewhere and there isn't, like a metal on metal creaking sound. Has anyone else here changed their entire exhaust? If so have u had similar problems? And does anyone have any idea what the hell is wrong here??????

i have full exhaust, are you sure nothing is rubbing on the subframe? mine used to make noise until i realized the mufflers were rubbing. and are you sure that it couldnt be just coincidence that it started when you put exhaust on it or just when the weather warmed up?

Check all fasteners, check for rubbing as suggested above, sometimes adding (or relocating/removing) hangers will alter the stresses and reduce noise as you describe.

it used to rub on the gas tank, but i fixed it. And its not from the weather warming up either. That used to be my excuse when it was cold outside, now its warm and its still doing it...

also check the tailpipes were they go over the axle sometimes they are too close to it, it did on my 01 so i had to pound the pipes into the muffler a little further becuase they were rubbing the axle when i went over large bumps
