Interested, would like to know the price. Plus without a tune, will the mpg still go up? I feel like without the primary cats the a/f ratio will be off and Ill be dumping more fuel causing less mpg than I'm getting now. I plan to keep the stock exhaust for sound reasons so Im wondering if the awful smell will be there with everything stock except the headers. Awesome work by the way, these things look legit.
