Ray, are her Flowmasters cat back or just the mufflers? I had the Flowmaster system on my '92 and loved it but I didn't think they made a cat back system for the C5. If I'm wrong I may be looking for another system. I've got the Magnaflow cat back with X pipe on it now and I would like it louder.
As far as the vendors at the show, I'm sorry I don't know. I didn't mean to hijack your thread.....
