Product Description

The SLN S58 ceramic-coated sports cat downpipes replace the compatible factory catalytic downpipe sections with high-flow 200-cell sports catalysts. They retain catalytic sections while changing exhaust flow and sound compared with the factory downpipes.

The ceramic coating is intended to limit radiated exhaust heat around the engine bay. The manufacturer specifies TIG-welded construction, 304 stainless-steel flanges and factory-style brackets and mounts.

Further information below.

FAQs

Is this an approved road-use emissions component?

SLN lists its decats, sports cats and emissions-system delete parts for off-road or motorsport use only. Do not assume that retaining a sports catalyst provides road-use approval.
