Important Note for S55 Owners:
As this system is unresonated, you may experience the "2k rasp" on a race or free-flow downpipe setup when shifting at low RPMs. While OEM downpipes aren’t very restrictive below 700hp with stock turbos, we recommend using 200-cell or similar high-flow cats for the best sound refinement and added volume compared to stock downpipes, especially if you're considering further upgrades to both flow and sound.
Unless otherwise noted, all RMD Performance products are guaranteed to be first-quality merchandise. Many products come with a manufacturer's warranty, which will be passed on to the original buyer.

These seatback covers are incredible! They literally fit perfect and are super easy to install. They bring the interior to the next level. Highly recommend especially if you have the carbon fiber interior trim.
