I'm looking for a cat back exhaust system for my 1998 zr2 sonoma it's got a 4.3 in it. I'd like a dual exit exhaust but can't find any for a 4x4 with the 4.3. Do any of you guys have an aftermarket exhaust system on your 4.3l zr2 Sonoma/ S10?
On most S10 4.3's the biggest improvement will be a better Y-pipe. The original is small diameter tubing that's poorly bent and is flattened even smaller in some areas. Combined with a free flowing cat and muffler there'll be a noticeable improvement.
Besides the muffler there isn't much to a cat back system for a 98 ZR2. Tailpipe? Price???
Summit has some good reasonably priced stainless performance mufflers:
Im looking into a complete new exhaust system headers,y pipe, cat and cat back dual exhaust, hopefully this will improve the sound significantly. Magnaflow eh, any certain series that sounds good with the 4.3??
