So I have a 22re in my 4runner with a header and I think 2 1/2" exhaust with a 40 series Flowmaster. In other words it sounds like the rest of the Toyotas on any trail or the ricer Hondas on the street. When I let of the gas it just releases the back pressure in a series of farts. Of course I can barely hear the person next to me let alone the radio. I need to keep a semi flat/oval muffler that can fit up tight. Anyone use something other than a Flowmaster that actually sounds good but not too loud. I guess I would prefer quiet over sounding good.
