I don't know how anyone can recommend a muffler or cat-back setup with the info you posted?

First you got to tell us if you got headers, cats, and muffler setup you have now?

i love my magnaflow also! its gotta be one of the most quite cat-backs. but i was thinking about putting a stock replacement muffler on to really quite it done, for a stealth factor. no one would know theres 416ci under the hood. especially with my 114 lsa cam. just need to find a stock type replacement with a 3" inlet

Dual/dual hands down. Not only does it flow fantastically, but it's also stainless, OEM quality, and sounds nice and quiet.
