Here is my 07 xb12stt with a Supertrapp from Summit. Used a 2 inch rt angle ss pipe, MIG welded a sleeve on it for the header, made new mounts, spent some time polishing on a wheel. Looks real clean, 12 discs with closed end, bottom end good, has a nice bark, but not car alarm loud. Still have stock instake, just with Techlusion, no back fire on overrun[cool]
