Another question for you Jeff ...
I noticed in your signature that you have headers, cats, & Corsa. On my 90 I just replaced the Borlas with Corsa thinking it would be somewhat closer to the Corsas I had on the 94 LT1 A4 ... forgot how loud the Corsas could be and louder still on a high revving LT5 with headers and NO cats. How much will it tone it down if I add cats to my setup. I already have the cats but they were set up with v-clamps for the Borlas and I don't have access to a good exhaust shop to make that mod at this time. Also, will you be at BG? If so, I want to compare your headers, cats, Corsas with my headers, no cats, Corsas. Thanks.
George

apologies to OP for highjacking the thread ... should have started a new thread ... I've already put the dunce cap on and I'm headed for the corner now.
