my exhaust always sounds really raspy
especially when my pedal is pushed at that exact spot where im going 40 mph

i dont know much about what could be the problem and quite frankly idk where to even start to look to find/examine where the problem might be
any help would be appreciated
thanks

It sounds like it might be the center resonator (right behind the main cat). This is a very common problem on our cars.
See part #2 in the diagram below.



Does it sound like a "buzzing" or a "can of bees" upon acceleration? It should probably be most annoying at around 2000-2500rpm.

It can easily be cut out and replaced with an aftermarket resonator from Magnaflow, etc. Some have just eliminated it all together and replaced it with a piece of 2.5" exhaust pipe

that sounds about right
its like that annoying sound where if you were to hear it without seeing the car that made it, you'd think "man, what a piece of crap"

thanks

you can cut it out and put a pipe there but some people have said the car makes a "fart" sound with it removed... yet to cut mine out... its doing the same thing

I have replaced mine with the Aero Turbine AR25 2.5" stainless steel resonator. You can get it for about 57.00 from Aero Exhaust at http://www.aeroexhaust.com/import_resonator_ar25.html

svxfiles has used these resonators on many exhaust systems, including his own, as well as mine HERE
