Borla 140034 muffler

This is the exhaust I put on my own E46 M3 car. It is very deep and throaty with all the rasp eliminated. It is quieter in the car and a better choice for those of you that spend a lot of time commuting and/or traveling.

Tip size is 3.14" = 79.756mm

Performance Gains:

Our car generated 292 RWHP on a Dynojet with the aFe intake, Superchips UK software, the new Borla midpipe available at the link below, and this muffler. Using 20% as the drive train loss, this would extrapolate to 365 HP at the crank, which would be an increase of 32 HP over stock.

Does exhaust flow concern you?

It should. The ability of an exhaust system to flow also represents its ability to allow your engine produce horsepower up it its potential. Check out this flow test showing the results of a Borla, OEM BMW muffler and an Eisenmann.
