Here is mine on the Dyno w/18" Magnaflow, Kooks headers, and a 2.5" x-pipe. http://youtu.be/uVgxEZ7THY4

X-pipe will give you more power but will have a higher pitch than the H-pipe. H-pipe will be a bit deeper in sound.

Here are a couple good articles that will provide a more details explanation.

I believe mine are 14256 polished, 5x9 oval, 2.5" inlet/outlet, center/offset. Non polished # is 12256.

They were on the car when I bought it so I'm not 100% certain on the P/N without crawling under the car with a tape measure and cross checking it with the site.

I know the preferred magnaflow part number has been posted before but I'm on my phone with limited search function abilities right now.

Flowmasters are for noise only, they don't flow that much more than the factory muffler.

If you want flow and sound, magnaflow or dynomax ultraflo's.
