The Z1 Infiniti G35 Cat-Back Dual Exhaust combines our most popular dual exhaust with our new Z1 Stainless Steel Y-Pipe into one convinient and well priced exhaust system.

The Z1 Motorsports M-Spec G35 Coupe Dual Exhaust was designed for the enthusiast looking for a dual exhaust that does not sacrifice power or sound! The race inspired muffler design produces a exhaust note with a signature growl.

Features include a fully tig welded construction with 16 gauge 304 stainless steel tubing. A 3" main pipe leads to our stepped V Band connection to ensure a positive seal ahead of the two mandrel bent, 2 1/4" sections connecting the Z1 Motorsports resonated mufflers with 4" tips in your choice of straight or slant cut style. With a signature growl at daily duty revs the belt under aggressive throttle applications is not to be missed.

This exhaust is LOUD, but with the newly included dual stage silencer the exhaust volume can be changed within minutes with basic hand tools, making early morning escapes to the race track an easy feat to achieve without waking your easily disturbed neighbor.

The Z1 Dual Exhaust weighs only 35.65lbs, approximatly 10.53lbs lighter than stock!

High Velocity Y-Pipe

The Z1 Stainless Steel Y-Pipe included in the Cat-Back exhaust was produced specifically for enthusiasts looking to increase horsepower and torque across the entire powerband while simultaneously improving exhaust note when combined with a full exhaust. Features a special 3-piece design with swedged slip joints, making installation a breeze! 2mm wall thickeness ensures maximum durability while thick laser cut flanges are utilized to ensure a proper seal with high resistance to warpage overtime.

Mandrel bent primary pipes provide smooth transitions to the large 3'' merge collector. The merge collector increases exhaust gas velocity and improves the scavenging effect. Exhaust scavenging makes an exhaust system more efficient, by improving the scavenging effect of the exhaust you allow for greater exhaust flow resulting in MORE POWER! In addition, an auxiliary exhaust bung is installed in the collector at the rear to allow for easy wideband installation or additional monitoring of exhaust gas temperature.
