Maximum flow sounds great yet not obnoxiously loud and no drone, also quality material/construction. All stainless & welded seams won't rust or blow out with quality packing that won't burn out or hold water if you have cat converters. You can buy cheaper muffs but you will pay for it. "Straight thru" type muffs are always the best for performance. Except for louvered core cherry bomb types.

A larger case controls sound better without creating restriction. This is the largest case that comfortably fits under the gbodys rear seats floor pan. It can be used in a gbody pipes kit as a bolt up. If you buy a gbody pipe kit get stainless clamps. I used them on my 442 for no power restriction AND great sound. I used their website locator to get the phone number for their nearest warehouse distributor called them and had them drop shipped to my door at wholesale. 8) Oh yea if you use all 3" pipe but with 2.5" tailpipes it both controls sound better and often aids in flow. The reason is as hot exhaust gasses cool they shrink then slow making the hot gasses behind them push them out causing back pressure. The smaller tailpipe keeps the velocity where its needed.
