I have finally decided to ugrade the pipes on my 84. It's factory tubing front to back. The cat's been gutted and the casing is badly mangled. I will be replacing it with a piece of exhaust pipe. Also, I need new mufflers. The old ones have been welded up and patched a few times (One tip has been re-attached, crooked I might add.........) I was thinking maybe buying a set of muffler delete pipes from Ecklers or Mid America or wherever it was I saw them. Any better suggestions. I will be driving the car next summer, but usually with straight pipes and a stock motor, most vehicles aren't that loud. Is the Crossfire vette any different? I want it to bark with authority at full throttle, but keep the noise to a minimum at cruising speed. Any suggestions as to what I can do? As I said, it's all factory 2 1/4" still with no cat.
