Magnaflow for the muffler after that it's pretty much up to you how you either exit it from the vehicle or dump it.

Here is what I did with mine and I couldn't be happier.

Sweet, then like someone else suggested, just cut the muffler out and install a better one.

Flowmaster 50 series with 2-1/2" duals from the muffler out

Sorry man, but I don't care for flowmasters. I put a pair of 40 series in place of my stock mufflers on my CTS-V and it felt like it hurt my performance. It also resonated like a ****. So I had the Flowmasters cut out and I had straight pipe welded in their place and my cabin noise was reduced. Go-figure. Also my performance increased alot.

go borla or flowmaster, ive heard the "baffle" design of flowmaster doesnt do much for our LS based engines.
