Performance
The factory downpipe on your N55 engine includes a restrictive catalytic converter that hampers exhaust flow and adds back pressure. Our PWG & EWG N55 Downpipe significantly reduces this restriction, resulting in faster turbo spool, increased power and torque, and a more aggressive exhaust note. Whether you choose the catless or high-flow catted option, you'll experience improved performance and an enhanced driving experience. Upgrading your downpipe is essential for those looking to maximize their Stage 2+ tuning potential.
In addition to power gains, the Palenon Performance n55 Downpipe provides a noticeable improvement in exhaust sound. While the downpipe is only a part of the overall exhaust system, upgrading it will amplify volume, especially during full throttle and cold starts.
