ISR Performance GT Single Exhaust - Hyundai Genesis Coupe 3.8

The ISR Performance GT Single Exhaust is a straight-pipe-style catback exhaust for the 2010-2016 Hyundai Genesis Coupe 3.8 V6. Straight 3-inch mandrel-bent stainless steel piping with a resonator AND a muffler, ending in single 4.5-inch polished tips. Built for mid-to-high RPM power and an aggressive note that suits the 3.8L V6 character on naturally aspirated and built power setups.

What It Does

Catback replaces the entire exhaust system from the cat back. The 3.8L V6 variant routes through a dedicated 3.8 Y-pipe (different from the 2.0T routing) and runs straight 3-inch piping back through a resonated front pipe and a rear muffler section, exiting via 4.5-inch polished tips. Unlike the 2.0T variant (which is resonator-only with no muffler), the 3.8 version includes a muffler to control the V6's naturally louder character into something aggressive without being uncivil. Mid-to-high RPM is where this exhaust comes alive.

Tip Style Variant

This is the polished tip version. For the burnt blue tip version, see IS-GT-GEN38-BT. The rest of the system is identical between variants.
