exhaust problems
Hey everyone, new to forum. I just bought a 1992 c4 with a lt4 engine and 6 speed manual trans. Car had a little exhaust noise all original. I just put flow master mufflers on no help. Car sounds good at idle and cruising but when you shift gears or race the engine it sounds awful. The exhaust sounds raspy, like tin cans for mufflers, just makes an awful sound. I live in a small town and do not have many people who known what to do but change parts. If anyone has any suggestion's let me known.

All caps is like yelling. Welcome to the Forum. Flow Masters are about the loudest mufflers on the market.
