ISR Performance Nissan 370z Single exit exhaust

 ISR Performance Single GT exhaust is a y-pipe back exhaust system made of mandrel bent stainless steel to ensure the highest reliability and quality. This 370z Single exit exhaust gives you all the advantages of unrestricted flow to maximum horsepower while retaining a deep and aggressive exhaust tone. This single GT exhaust is the perfect combination for both naturally aspirated and forced induction applications. Combine with an ISR 370z Y-pipe and test pipes or High Ground Clearance Headers to finish off your exhaust system.

Lighter then factory exhaust 
Precision TIG welded Stainless Steel
Brushed Stainless finish 
Polished tip and muffler
3" exhaust with 4.5'' muffler tip

The ISR Performance 370z / G37 Y-pipe utilizes 2.5" stainless steel piping along with bellowed flex sections running from the 2 bolt catalytic converter flanges back to the high performance velocity merge. The Y pipe then steps to 3" stainless piping coming out of the velocity merge to the rear 3" exhaust flange. The Y pipe also features an integrated dimpled gusset plate tying the two individual runners together for increased strength and rigidity.

The ISR Performance Y pipe was designed to provide the best possible exhaust tone, ground clearance, and performance, all at an affordable price!
