Porsche 982 718 Boxster & Cayman 2.5T Catted Downpipe Non-OPF With GT4 Body Kit (2016–Present) | IPE Performance Exhaust

Optimise performance and maintain refined drivability with the IPE Catted Downpipe Non-OPF Version for Porsche 982 718 Boxster and Cayman 2.5T models fitted with a GT4 body kit. Designed to improve turbo efficiency while ensuring proper fitment with GT4-style rear conversions, this upgrade delivers enhanced responsiveness and a deeper performance exhaust tone.

The high-flow catalytic design allows exhaust gases to move more efficiently through the system, reducing restriction and supporting faster turbo spool.
