exhaust question... 94 turbo

858 Views 6 Replies 6 Participants Last post by  Jason R
I have a 94 IDI turbo,I have a full 3" exhaust with no muffler,it sounds good until higher rpm then it starts to sound like a glass pack,I hate that sound,if I use a 4" complete from downpipe back will that go away? It seems that with a 3" DP and the rest 3" it may still be restricted,any advice?

I think you are stuck with the wouldnt matter if you had a 10" stove pipe off of a could kill it off by adding a performance muffler. I think that the ~5.5' of straight section is what causes builds a harmonic vibration in the exhaust frequency itself, and leaves the pipe as a chopped up reverberation....If you put a straight through type hypermax muffler(the kind that looks like it has chain link fence inside) in the middle of that long straight section, I think that it would disrupt that exhaust reverberation enough to smooth the sound out...Personally, I dont mind the cackle...I still get cackle with my exhaust system listed in my signature.
