Also when people are behind me during spirited driving, they say the aroma is so bad, their eyes burn My 99 SVT has 118k on it, so i'm thinking its the cat. It couldnt really be anything else... I have headers with MIL elims, optimized y pipe, Magnaflow Res, and Magnaflow mufflers. What can I expect if I weld a straight pipe in place of the cat? Performance gain/ loss? Sound good/ bad?

I assume since your cat is not working properly, if you put in a test pipe on it will increase the sound (maybe rasp), allow it to flow more. The down side is you will still have the products left over from the incomplete combustion that will cause eyes to burn, as well as pollute the environment. Just get a high flow cat. 98.5 Black SVT with 34k miles Build #5683 Born on 4\15\1998 WR Headers GMK CAI Blaupunkt system fiberglass tweeter pods L.E.D. tail lights in the works

I doubt it could be too loud with a resonator and 2 mufflers... Right?
