With the success of our exhaust systems for the VQ35DE and VQ35HR, we set out to design a solution for VQ37VHR. The SOHO Motorsports single exit catback exhaust system is constructed from 3″ diameter T304 18 gauge stainless steel piping providing a 55 percent decrease in weight over the stock exhaust. This creates a more exotic and aggressive sounding exhaust note, without the rasp and deafening tone some other single exit exhausts create. https://www.youtube.com/watch?v=sFgCoL7VbO0&t Car had roughly 500 miles on it and only modification was the SOHO single exit exhaust. https://www.youtube.com/watch?v=PGHoHiAjS7U Unfortunately out of focus but is also stock besides single exit exhaust. https://www.youtube.com/watch?v=8sT8UX2JSwI Same car was Video #2. The system was designed to work with both factory Y pipe and our own SOHO y-pipe that we have become known for.
