Midpipes
1 product
Our G80 M3 midpipe is the IRL High Flow single midpipe, which also fits the G81 Touring and the G82/G83 M4. It’s a 3.5-inch mandrel-bent stainless steel pipe supplied with a brace and all the hardware, and you choose between resonated, non-resonated and titanium versions. IRL builds it for professional installation and sells it for off-road use only.
Midpipes buying guide
Resonated, non-resonated or titanium
- Resonated: takes out the metallic rasp the S58 can have with a single midpipe, especially alongside high-flow cats.
- Non-resonated: the loudest, rawest of the three.
- Titanium: IRL's titanium option, for owners who want titanium rather than stainless steel.
Frequently asked questions
What comes in the box with the IRL midpipe?
The midpipe itself, the brace and the hardware needed to fit it. IRL recommends professional installation, so plan on a shop with a lift rather than a driveway job.
Is the IRL midpipe street legal?
IRL sells it for off-road use only and says it isn't intended for any use that breaks the law. Rules on exhaust changes vary by state, so check yours before you fit it to a car you drive on the road.
