Downpipe Back

Downpipe-Back Exhaust Systems

A downpipe-back exhaust system replaces everything from the turbo downpipe flange all the way to the tailpipe tips, giving turbocharged vehicles maximum exhaust flow improvement in a single bolt-on package. By replacing the restrictive factory catalytic converter section, mid-pipe, and muffler together, a downpipe-back system delivers the largest exhaust-side power gains available for turbo platforms.

OneFastShop carries downpipe-back exhaust systems including stainless steel construction, single and dual exit configurations, high-flow catalytic converter and catless options, resonated and non-resonated mid-sections, polished and black exhaust tips, and direct-fit applications for popular turbocharged platforms.

Every downpipe-back exhaust at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're building a full turbo-back exhaust upgrade or replacing the entire exhaust from the downpipe flange rearward, OneFastShop has the system.
