Subject: Re: Has any body installed this ? Exhaust question by bogus on 2011/3/7 2:42:09 The 1990 exhaust is rather restrictive. I would go looking for a stock 1992 LT1 cat back, then put on a pair of bullet cats. There is a method to my madness - One is, the cat helps cut polution. No question. Sure, it is a trade off, but I prefer the output of the cat to what a car COULD be spewing. I am concerned that some areas that were exempt from testing could get tested. Initially, they will only do sniff tests... and I don't see states taking on CA style emissions and retroactively applying them. An LT1 catback should be nearly free. Check local Corvette vendors and shops. Converting your existing down pipes should work ok, but if you can find a couple of used LT1 cats, more power to ya. If they are shot, who cares, get a couple of Random Tech or Carsound cats welded in to replace them. If you want, you can then do an aftermarket muffler or what not. The C4 coupe is prone to in-cabin drone. It is caused by the location and tone of the exhaust. Corsa, tho expensive, does a nice job of killing to resonance. The LT1 exhaust is pretty good and is well made. But will drone a bit. However, I think it will liberate 30hp on the cheap! |
