ISR Performance E36 LS Swap Y-Pipe

The ISR Performance E36 LS Swap Y-Pipe is the fabrication-free Y-pipe purpose-built for LSx swaps in the E36. Bolts to the 2-bolt flanges at the rear of our HGC LS swap headers, then routes through to any existing ISR Performance E36 rear exhaust section. Designed as one piece of a complete ISR E36 LS swap exhaust path.

What It Does

Y-pipe section that bridges the LS swap headers to the rest of the E36 exhaust system. The included extension pipe handles the length difference between the LS swap exhaust path and the factory E36 routing, and the 2-bolt flanges mate cleanly to our HGC headers. Once installed, you can bolt any ISR Performance off-the-shelf E36 rear exhaust section (Series II MBSE or EP Dual catbacks) onto the back end for a complete LS swap exhaust setup.

Fitment

Requires the ISR Performance E36 LS swap kit and HGC LS swap headers:

• IS-E36-LSMB (LS swap mount kit)
• IS-SSHD-E36LS (HGC LS swap headers, 1 3/4")

Will not work without these components in place. Designed to mate with any existing ISR Performance E36 rear exhaust section (Series II MBSE Resonated catback IS-S2MBSER-E36, Series II EP Dual Resonated catback IS-S2EPDR-E36, or the matching modular rear sections).
