ISR Performance EP Dual Exhaust - Infiniti G35 Coupe 03-07

The ISR Performance EP Dual Tip Exhaust is a Y-pipe back exhaust system for the 2003-2007 Infiniti G35 Coupe (V35 chassis, RWD). Mandrel-bent stainless steel with a 3 inch resonated mid pipe and twin 3 inch polished exit tips. Designed specifically for the G35 Coupe chassis, not adapted from a 350Z exhaust like many cheaper options on the market.

What It Does

Y-pipe back exhaust replaces the entire exhaust system from the Y-pipe to the tips. The 3 inch mandrel-bent piping maintains a consistent inside diameter through every bend, which keeps exhaust velocity up on the VQ35DE. The dual 3 inch tip configuration delivers a more aggressive presence and louder tone than a single-exit system, while the resonated mid pipe keeps highway drone controlled.

Why a G35-Specific Design Matters

Many aftermarket G35 Coupe exhausts on the market are actually 350Z exhausts with extension pipes added to account for the longer G35 wheelbase. That approach almost always produces poor fitment, awkward ground clearance, and a system that hangs lower than it needs to. The ISR EP Dual is designed from the ground up around the G35 Coupe chassis dimensions, so it fits correctly and clears the chassis as intended without adapters or extensions.

Critical Installation Note: Bumper Modification Required

Due to the twin 3 inch tips, the rear bumper will require either trimming or a "bumper tuck" for proper fitment. The dual tip configuration is wider than the factory exhaust exit, so the stock bumper cutouts won't accommodate the tips without modification. Plan for this work as part of the install.
