Don't know if you feel like comin to ohio for it, but if you do I will make you a cat back system. You pick the muffler (4.5 inch tip), Aluminum or stainless pipes, cat/no-cat/resonator, pipe size. All I need is about a day and a half with the parts and your car. Let me know.

I only charge 150 - 200 plus parts so altogether you may only spend 350 depending on what metal you want used in the making of the system. However you still may end up as high as 550. Still cheaper than most cat-back systems out there.
