ISR G37 Coupe Exhaust | Single Exit | Boost Power & Sound - 3" T304 Stainless | VQ37VHR Catback | JDM Drift Spec | Deep Aggressive Tone | Direct Bolt-On for 2008-2013 G37 Coupe RWD

Boost power and sound on your 2008-2013 Infiniti G37 Coupe RWD with the ISR GT Single Exit Catback Exhaust engineered to delete the heavy, restrictive stock dual muffler system and replace it with a lightweight 3" T304 stainless steel single-exit layout that maximizes exhaust flow, drops weight off the rear, and delivers the raw, drift-inspired VQ tone ISR Performance built its name on, because the GT uses full 3" mandrel-bent piping from the y-pipe flanges all the way back to a single high-flow muffler and 4.5" slant-cut, burnt-tip cannon that eliminates backpressure and exhaust turbulence to unlock a proven 12-17whp and 11-15wtq with instant throttle response, violent mid-range torque, and a screaming top-end that pulls clean to 7500 RPM, and the sound is pure single-exit aggression with a deep, bass-heavy idle and cold start that builds into a loud, raspy, exotic VQ wail at wide-open throttle that makes the G37 Coupe sound like a Formula Drift car, while the large single muffler and integrated resonator are specifically tuned to kill the worst 2000-3000 RPM highway drone so you get all the volume when you’re on it without the cabin buzz and vibration that straight-pipe singles are known for, and the entire cat-back is fabricated from heavy-gauge T304 stainless with full-penetration TIG welds, reinforced hangers, and a brushed finish that resists corrosion, cracking, and heat discoloration through years of daily driving, canyon runs, and track days, and the 4.5" burnt single-exit tip with laser-etched ISR logo gives your G37 Coupe the clean, JDM single-exit look that deletes the bulky duals, showcases the rear diff and suspension, and sets your car apart from every other dual-tip G on the road, and fitment is 100% direct bolt-on for 2008-2013 G37 Coupe RWD using all OEM mounting points with zero cutting, welding, or bumper trimming required, tucking high and tight for perfect ground clearance and clearing the rear subframe, sway bar, and chassis braces with no rattling, interference, or alignment issues, and the kit ships complete with multi-layer steel exhaust gaskets, Grade 10.9 hardware, and polyurethane hangers for a solid, leak-free install that takes 1-2 hours on a lift, and it pairs perfectly with ISR, Z1, Motordyne, or other test pipes and y-pipes to build a full 3" VQ37VHR exhaust that sounds as violent as it performs, so if your G37 Coupe sounds stock, feels choked, and you want single-exit aggression, real weight savings, and serious horsepower without paying $1400+ for JDM brands, the ISR GT Single Exit Exhaust is the ultimate bang-for-buck cat-back to boost VQ power and sound, and every system is jig-welded, pressure-tested, and QC inspected for flange flatness, tip alignment, and weld penetration so you get ISR’s proven fit, finish, and tone without the leaks, drone, or fitment nightmares you get from cheap eBay singles.
