if your looking for a sound that you can legally get away with on a hot big block....4(2x2) mufflers reducing to 2x 2 1/2" or less outlets.

only way to get these machines quiet.

the resonator you tried meant glasspack, right? or was it just a tip? anyways install the glasspack before the muffler to get that benefit.

no 3" outlets. it opens up a new group of low harmonics that penetrate. its affecting people not even able to look at your car...thats kind of stupid.

didnt some magazine do a backpressure study and found that rear tailpipes account for some "measureable" forward thrust?
