Hey guys,
I'm working on a 1994 GMC K1500 4x4 with the 5.7 engine. It's fully optioned out with ALL the heavy duty options fortunately. Eventually, it will get a fresh, warmed over engine with headers and true dual exhaust, but for now I'm just doing some much needed maintenance with a few upgrades here and there, and putting it back on the road. I bought it not running, and needing lots of various things repaired. I've thrown a new timing chain in it, rebuilt the throttle body while doing hi perf mods to it, and added an adjustable fuel pressure regulator. A hipo fuel pump is next, etc., and it's had a complete tune up.
Anyway, I was working under it this evening, and was wondering about adding a free-er flowing, more agressive sounding muffler for now. The single unit that is on it is a monster. It's a great big round unit, but here's the odd part--> it's got 2 3/4" inlet and outlets. No typo; 2-3/4 inches. I've been doing this stuff for a long time, but I've never run into that size before.
Does anyone make performance mufflers in that size??
Thanks,
