Invidia Gemini Exhaust for G37 | 370Z | Q50 - True Dual 70mm Catback | T304 Stainless | VQ37VHR Performance & Sound | Deep Tone with Drone Control | Direct Bolt-On

Elevate your VQ37VHR with the Invidia Gemini Catback Exhaust designed for 2008-2013 Infiniti G37 Coupe/Sedan, 2009-2020 Nissan 370Z, and 2014-2015 Infiniti Q50 3.7L RWD by replacing the restrictive, quiet factory cat-back with a true dual 70mm T304 stainless steel system that maximizes exhaust flow and delivers the aggressive yet refined sound Invidia is known for, because the Gemini uses large-diameter 70mm mandrel-bent piping from the y-pipe flanges all the way back to eliminate backpressure and increase exhaust velocity, unlocking a proven 10-14whp and 8-12wtq with noticeably sharper throttle response and harder mid-range torque that pulls clean to 7500 RPM, and the sound signature is where Gemini stands out with a deep, throaty VQ growl at idle and low RPM that builds into a smooth, exotic, race-inspired tone at wide-open throttle without the high-pitched rasp or ear-piercing drone that kills daily drivability on other systems, thanks to the dual high-flow mufflers and integrated mid-pipe resonators specifically tuned to cancel the VQ’s 2000-2800 RPM drone frequency while keeping cold starts and WOT pulls aggressive and head-turning, and the entire system is crafted from heavy-gauge T304 stainless with full TIG-welded seams, reinforced 3-piece construction for easier install, and a brushed finish that resists corrosion, heat bluing, and cracking through years of street and track abuse, and the dual 4.5" slant-cut, rolled-edge, polished stainless tips with laser-etched Invidia logos fill the rear bumper perfectly on G37, 370Z, and Q50 for an aggressive OEM+ look, and fitment is 100% direct bolt-on using all factory mounting points with zero cutting, welding, or modifications so it mates to the stock y-pipe or any aftermarket y-pipe and test pipes with perfect tuck, ground clearance, and alignment, and it clears rear diffs, sway bars, chassis braces, and subframes on RWD, manual, and auto cars with no rattling or interference, and the kit ships complete with multi-layer steel exhaust gaskets, Grade 10.9 hardware, and new urethane hangers for a leak-free, rattle-free install that takes 1-2 hours on a lift, and the Gemini balances performance and refinement so you get real horsepower and that signature deep Invidia tone without waking the neighborhood on cold starts or getting droned out on the highway, and it pairs perfectly with Invidia or other test pipes, headers, and intakes to build a full bolt-on VQ37VHR exhaust that sounds exotic and performs like it, so if your G37, 370Z, or Q50 3.7L sounds stock, feels restricted, and needs deep tone with true drone control, the Invidia Gemini Exhaust is the go-to cat-back for unlocking power, sound, and quality, and every system is jig-welded, pressure-tested, and QC inspected for flange flatness, tip alignment, and weld penetration so you get the legendary Invidia fit, finish, and sound without the leaks, drone, or fitment issues you get from eBay brands.
