need help with exhaust noise

armymike63b · March 9th, 2008, 06:20 PM

i just put a o/r x-pipe on my 04 mach 1 and now i have alot of the engine and exhaust noise mainly around the shifter/radio area how can i damper this noise some and is it normal for it to burn really rich and smoke a little now ???

get a tuner for the richness

and I dont know why you would have extra engine noise or any different noise around the shifter. if everything was installed correctly the sound should be going out the tail end. lets see what anyone else thinks. thats all i can say

+1 What brand x-pipe is it? I had to get under mine twice do fix 2 small leaks I had. No biggy but sometimes the mid pipes can be in a little bit of a bind and you can have a little leak. I would check there.

I had the same issue, check the mid pipe where it connects to the manifold. The guy I bought my car from put the exhaust on, and he must forgotten to tighten the left side up they loosened up and I had an exhaust leak I had to buy some bolts from the dealership for $13.00 it's fixed now. Took 5 minutes
