So after hours of research, I found out that the horsepower generated from an exhaust purely has to do with the diameter of the tailpipe and nothing else since it all comes out from there. Then I googled a few exhausts that yielded HP numbers in the hundreds of HP and came along this one. Those are made by a company known as R.I.C.E. (Race inspired catback exhaust) from the heart of Japan, Tokyo.
