Description

RVNG N55 Race Downpipe – SS304 Stainless Steel

For 4” Electronic Wastegate N55 Models

Unlock hidden performance with the RVNG Stainless Steel Race Downpipe, engineered specifically for 4” electronic wastegate N55 applications. By replacing the restrictive factory catalytic converter, this direct bolt-on upgrade slashes backpressure, allowing for faster turbo spool, increased power, and a deeper, more aggressive exhaust tone.

Constructed from high-quality SS304 stainless steel and TIG-welded for strength, this downpipe features smooth mandrel bends and CNC-machined flanges for perfect fitment and long-term reliability. Backed by RVNG’s Lifetime Warranty and Fitment Guarantee.

Important: To confirm compatibility, please send a clear photo of your turbo wastegate from the engine bay before ordering.
