Killer Chevy 93
Newbie
Yes, I replaced the manifolds with Flow Tech headers, ditched the 3" cat. Kept the stock y-pipe for now as I cannot find flanges to build a mandrel bent y-pipe, replaced the rest of the exhaust with a single 3" mandrel bent system with a 3" in and out "Shuttleworth" truck muffler, very quite and free flowing.
