im planning on building about a 600 hp motor, so im planning on using hooker long tubes, but from there back im undecided, so thats where i need help, i want this thing to breathe, but i also want a unique sound, something unlike every other v8 with a flowmaster... i was thinking about gmmg, but i really dont like the price tag, and thinking about corsa, also expensive, or an slp system... ive never heard gmmg in person but ive heard that its very unique... with this much power would i need something more custom or would these systems work well enough?

 

duals or single?

I'm a fan of a 4" single...4 or 5" muffler dumped before the axle.

I did a Spintech on a 500+hp 396SBC....I dig it.

 

well id like to stick to duals or at least something that comes out of the bumper

 

Did a Mufflex 3 1/2". Modified alot of it since it did not stay together with the slip fit type clamps. App... 97ss M6 383 D1. After alll hardpipe on the blower, the cats were blown out. I used a 3 1/2" CCI 3 disk insert before the axle kick to a Spintech single muffler and single 3 1/2" final pipe. It was too loud. Also used a QTP dump due to a need for flow with the D1.
Hope this helps...
