So the ebay mufflers I see online, are they any good? I don't just see myself spending 200 plus on a exhaust.. I have the resonator cut off, what type of mufflers could I get to give it a decent V8 sound. :th_jester:

Ebay could mean like 500 different brands from china or wherever. What exactly are you looking at?

Magnaflow or dynopro mufflers are under 100 each when you only need like 2 1/4in sized mufflers.

Just be aware that any aftermarket muffler will sound like a helicopter when it goes down into 4 cylinder mode. The factory mufflers do a better job at muffling that sound. Ideally you'd want to disable the AFM/DoD system before it gives you a problem anyway.

Thanks, I have DOD disable in tune already. I already cut resonator off, just wanting something that gives a better V8 sound. Not a real performance boost.. I did check out the site and it had some good stuff in it, thank you.
