Hemi Cat-back Exhasut Dyno Results?
Of the 3 or 4 cat-back exhausts available for the Hemi engine does anyone have some dyno results. I know Flowmaster (Flowmaster_Dyno) has a graph of their exhaust system but no others seem to post anything on what performance gains they provide. Anybody have their own dyno test results?

I would trust a manufacture's dyno plot for about as far as I could throw the exhaust. That being said it wasn't like the flowmaster chart looked like an outlandish claim.
As long as the diameter is right, has a crossover and flows well etc most kits should be more or less the same as far as gains (I'd bet).

Love the sound, fitment required a but if tweaking and she definately drones a bit at 2200-2500 when cruising and the mds kicks in but overall for the price I paid ($560 shipped) I'm very happy with it!

Cmil527,
im stuck between flowmaster an magnaflow... Heard flowmaster is too loud sometimes but it keeps the muscle sound. And magnaflow is too quiet kinda like a benz or bmw. What i dont want is alot of cabin noise or the high pitch rattle at high rpm, like the stocks have. Can you post a sound clip of yours or maybe some more info to help me decide. The shop im doing it at will be removing the rear cats replacing with an x-pipe and 2 1/2 pipping from there into whatever exhaust i choose. Thanx for your help hope to hear from you or anyone else about this soon..
