Really quiet muffler that flows 1/2 decent? - 06/29/11 04:57 AM
Just like it says. A friend wants his 360 to be really quiet but make a little more power, he is set on getting duals while he replaces his rusted out EX but wants it really quiet. Also what is a good size, I am thinking 2.25
The engine is a 5.9 magnum with heads shaved .030 very mildly ported heads, we are gonna throw in a roller cam from a 5.2 mag since we have it sitting around and it is a hair bigger. We are also gonna try one of the new hughes air-gap intakes since the motor is EFI and mabey a set of 1.7 MP roller rockers and some GM v6 behive valve springs. I may try to find a cheap set of the bigger 92 93 ex manifolds while we are at it since he wants it super quiet and cheap.
