ISR GT G37 Sedan Single Exit Exhaust | Unleash Power & Sound - 3" T304 Stainless | VQ37VHR Catback | Deep Tone Single Exit | Aggressive Drift Spec | Direct Bolt-On

Unleash the VQ37VHR in your 2009-2013 Infiniti G37 Sedan RWD with the ISR GT Single Exit Catback Exhaust engineered to ditch the heavy, restrictive, and quiet factory dual muffler setup for a lightweight, aggressive 3" T304 stainless steel single-exit system that saves weight, maximizes flow, and delivers the deep, raw, drift-inspired tone ISR Performance is famous for, because the GT uses full 3" mandrel-bent piping from the y-pipe back into a single high-flow muffler and 4.5" slant-cut, burned-tip cannon that eliminates backpressure and turbulence to unlock a proven 12-16whp and 10-14wtq with instant throttle response and savage mid-range torque that pulls hard to 7500 RPM, and the sound is pure ISR aggression with a deep, bass-heavy idle that rolls into a loud, raspy, exotic VQ scream at wide-open throttle that turns heads and clears tracks, while the large single muffler and integrated resonator are tuned to control the worst 2000-3000 RPM drone so it’s loud when you want it but doesn’t vibrate your teeth out on the highway like straight-piped setups, and the entire cat-back is built from heavy-gauge T304 stainless with full TIG-welded seams, reinforced hangers, and a brushed finish that resists corrosion, cracking, and heat bluing through seasons of street, drift, and track abuse, and the 4.5" burnt single-exit tip with laser-etched ISR logo gives your G37 Sedan the clean, JDM drift look that deletes the bulky duals and showcases the rear diff for a motorsport stance, and fitment is 100% direct bolt-on for G37 Sedan RWD using OEM mounting points with zero cutting or welding, tucking high and tight with no bumper trimming required and clearing the rear subframe, sway bar, and chassis braces with perfect alignment and no rattling, and the kit ships complete with multi-layer steel gaskets, Grade 10.9 hardware, and polyurethane hangers for a leak-free, solid install that takes 1-2 hours on a lift, and it pairs perfectly with ISR, Z1, or other test pipes and y-pipes to build a full 3" VQ exhaust that sounds as mean as it performs, so if your G37 Sedan sounds stock, feels choked, and you want single-exit aggression, weight savings, and real power without spending $1200+ on JDM brands, the ISR GT Single Exit Exhaust is the best bang-for-buck cat-back to unleash VQ sound and performance, and every system is jig-welded, pressure-tested, and QC checked for flange flatness, tip alignment, and weld penetration so you get ISR’s proven fit and finish without the leaks, drone, or fitment headaches you get from cheap eBay singles.
