ISR GT Q50 Single Exit Exhaust | Unleash Power & Sound - 3" T304 Stainless | VQ37VHR Catback | Drift-Spec Single Exit | Deep Aggressive Tone | Direct Bolt-On for 2014-2015 Q50 3.7L RWD

Wake up your 2014-2015 Infiniti Q50 3.7L RWD with the ISR GT Single Exit Catback Exhaust built to delete the heavy, quiet, and restrictive factory dual muffler system and replace it with a lightweight 3" T304 stainless steel single-exit setup that drops weight, kills backpressure, and delivers the raw, drift-inspired VQ sound ISR Performance is known for, because the GT runs full 3" mandrel-bent piping from the y-pipe flanges straight back to a single high-flow muffler and 4.5" slant-cut, burned-tip cannon that frees up exhaust flow to unlock a proven 12-17whp and 10-14wtq with instant throttle response, harder mid-range torque, and aggressive top-end pull to 7500 RPM, and the tone is pure ISR with a deep, bassy idle and cold start that rolls into a loud, raspy, exotic VQ scream at wide-open throttle that makes the Q50 sound like a track car, while the large single muffler and built-in resonator are tuned to knock down the worst 2000-3000 RPM highway drone so you get single-exit volume without the cabin vibration straight-pipe setups 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 fights corrosion, cracking, and heat discoloration through daily driving, drifting, and track days, and the 4.5" burnt single-exit tip with laser-etched ISR logo gives your Q50 sedan the clean, aggressive JDM look that ditches the bulky duals, showcases the rear diff, and sets it apart from every other quiet Q50 on the road, and fitment is 100% direct bolt-on for 2014-2015 Q50 3.7L RWD using all OEM mounting points with zero cutting, welding, or bumper trimming required, tucking high for perfect ground clearance and clearing the rear subframe, sway bar, and chassis braces with no rattling or interference, and the kit includes multi-layer steel 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, or other test pipes and y-pipes to build a full 3" VQ exhaust that sounds as violent as it performs, so if your Q50 3.7L sounds stock, feels choked up, and you want single-exit aggression, weight savings, and real horsepower without dropping $1500 on JDM brands, the ISR GT Single Exit Exhaust is the best value cat-back to unleash VQ power and sound, and every system is jig-welded, pressure-tested, and QC inspected for flange flatness, tip alignment, and weld quality so you get ISR’s proven fit and finish without the leaks, drone, or fitment issues you get from cheap eBay singles.
