Well, they do have the straight piped ones for under $300 on eBay and Amazon but otherwise, I think you are thinking of OBX and honestly it and MBRP may be from the same manufacturer... but honestly I'm not sure why the Tsudu exhaust isn't discussed more. 2.75" for less fitment and rubbing issues, sounds great and only $360 shipped... only thing that kind of sucks is that it has a huge 4" ricer tip that comes straight out of the supplied muffler at the full 4" size, it's not a 2.75"to 4" tip that's easy to replace.
