Ok, I will be doing some mods on my 1990 35th S/C and I am concidering what exhaust to run. The parts going along with the exhaust will be a 3" intake tube with a cone filter, a 5% overdrive pulley and an intercooler fan. I am looking at the flowmaster catback with the resonator and also removing the cats altogether. my questions are will this exhaust setup sound like crap? I don't want the little rice burner sound. And will the flowmaster piping and lack of cats be enough to help prolong the life of the headgaskets with a 5% overdrive pulley?
