Many many months of testing and construction was put into this exhaust system before it went into production. And now it is here! The all new Agency Power Nissan 370Z catback exhaust. The twin muffler with single 4inch tips sounds quite amazing as you can tell by the sound clip below. It is all T304 stainless steel that has been mirror polished and TIG welded.

Because of the reduction in back pressure, most normally aspirated cars drop low end torque with aftermarket exhausts. Check out more pictures and info on this Nissan 370Z Catback Exhaust here.
