Active Autowerke Mid-Pipe with X-Pipe G80/G82 M3/M4

OVERVIEW

This exhaust system upgrade was designed and engineered to work with most after-market exhaust systems/mufflers on the market today with only two cuts needed in the stock mid-pipe. It is a bolt-on that can be performed by most and the stock mid-pipe can also be reinstated if needed. The X-Pipe design has a scavenging effect that yields modest horsepower gains by increasing flow and removing the two sets of resonators.

SPECS

• Durable 100% 304 stainless steel construction
• Only a single cut needed, with factory-style flanges and clamps
• Installs to all systems that use factory-style fitting
• One-year warranty against rust
• Optional 100-cell flat cat variant replaces (not removes) the restrictive secondary cats for a deeper sound

PARTS INCLUDED

• 1x mid-pipe with X-pipe (straight pipes or 100cpi flat cats per selected variant)

TECH RESOURCES

• Replaces the stock mid-pipe for better sound and flow.
• The X-Pipe scavenging design yields modest horsepower gains by increasing flow and removing the two sets of resonators; an optional 100-cell flat-cat variant (11-087C) replaces the restrictive secondary cats for a deeper sound.
