The Z1 Race Cat-Back Dual Exhaust for the Infiniti G37 blends performance, visual appeal, and sound quality into one nicely-priced package. This exhaust is best suited for performance-minded enthusiasts that are looking for an exhaust with the highest power potential. We find it does exceptionally well on forced induction applications where the highest flowing exhaust is needed.
This exhaust is crafted from 304 stainless steel and tig-welded to perfection, designed and engineered with principles identical to our Z1 Modular Y-Pipe, putting sound and build quality first. Cast stainless steel flanges are tig-welded to 3'' stainless steel piping and feed a large 3'' cast merge collector. The design of the cast stainless steel merge collector reduces disruption in exhaust flow, providing exhaust gasses with a smooth transition, increasing exhaust gas flow, and improving exhaust scavenging. This maximizes exhaust performance for more power! Behind the merge collector are two resonators, tig welded in the mid-pipe. The purpose of the resonators is to reduce unwanted rasp and drone and help the system produce a clean exhaust note. From there, mandrel-bent pipes provide smooth transitions to a two 6'' muffler that exits on both sides of the rear bumper. Included with each muffler is a removable dual-wall silencer, used to reduce sound output.
Our race exhaust is Z1's choice for enthusiasts that need a free-flowing dual exhaust and want to minimize the overbearing rasp and drone that the VQ's produce.
Options:
Included Y-Pipe - Purchase of this exhaust includes your choice of either the Z1 Standard Y-Pipe, Z1 AWD Y-Pipe (for G37X) or Z1 Modular Y-Pipe. You can choose the standard configuration or upgrade to a resonated or non-resonated Z1 Modular Y-Pipe.
Muffler Tip Style - Choose between a slant-cut tip and a straight cut-tip on the muffler!
The dyno test above was performed on a completely stock 2009 370Z. This 370Z gained a total of 12whp and 7tq with the cat-back dual exhaust. You can expect even more power when paired with other intake and exhaust modifications!
