SLN Performance S55 F80 F82 200 Cell Catted Downpipes

DESCRIPTION

Improved the sound and performance with the SLN Performance S55 F80 F82 200 Cell Catted Downpipes for BMW M2 Competition, M3 & M4. Constructed with 304 Stainless Steel including reinforced turbo flange, for optimum flow with proven performance, adds up to 70bhp when combined with a stage 2 tune. The smooth bends one piece design decrease turbulence and increase flow at the same time without any restriction nor unnecessary welds that creates weakness found on other downpipes. 

With the unique flex section design similar to the flex section found on the OEM downpipe, extreme heat produced by the turbo causing expansion which cracks the downpipe is no longer an issue. The flex section also reduces stress of the turbo flange for a long lasting performance and eliminates unnecessary movements.
