On the S65 V8 M3 models, the stock exhaust headers flow very well while the catalysts present the largest obstacle and power loss. the Macht Schnell Bypass Track Pipes were designed specifically for race/track use, and offer a cost-effective means of removing the 400 cell restrictive primary catalytic converters on all 2008-2013 M3s. Bypass Track Pipes allow you to make two single cuts to your stock midpipe section, removing the catalytic converters, and clamping the largest diameter straight pipe in their place using the provided high-end/premium exhaust clamps. This eliminates the largest source of exhaust restriction, unleashing considerable power gains (~20hp) and a very obvious improvement in acceleration.
Macht Schnell Bypass Track Pipes permit you to retain your OEM secondary cats and resonators, keeping noise levels tame enough for even the most stringent sound limitations found at many track events (nearly stock decibel levels), and also keeping costs to a minimum. No welding is required for installation, simply cut and bolt into place using supplied exhaust clamps.
Aftermarket software required to prevent Check Engine lamp from illuminating.
Bypass Track Pipe Features:
- Full Stainless Steel Construction, with mandrel bends for optimum flow
- Straight shot design for zero restriction and high velocity
- Gains as high as 20hp/20lb-ft TQ with no aftermarket software
- Retains OEM O2 locations
- Retains use of OEM crush gaskets
WARNING:Â Please note that certain aftermarket exhaust systems may not comply with applicable US (including California) laws and regulations, and may therefore be prohibited for use on highways or roads, or on roads or vehicles otherwise subject to emissions control requirements. California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system.
Macht Schnell parts or exhaust systems/components used or intended for use on â€œracing vehiclesâ€ (i.e. a competition vehicle used exclusively for competition on closed-course circuits) do not require an exemption or Executive Order from CARB to be sold in California. However, such parts are prohibited from use on California public highways or roads, even if occasionally used â€œoff-road.â€
IND Distribution nor any of its subsidiaries make any representation that the products comply with the air and/or noise emissions laws, or labeling laws, of any jurisdiction.

EMISSIONS WARNING / USA:
Various U.S. states and the U.S. federal government have individual laws regulating the use of aftermarket exhaust parts and systems, especially as those parts and systems modify, remove, or replace original equipment catalysts. Please consult the appropriate laws in your area before installing any aftermarket part or system on your vehicle to ensure compliance with all applicable laws. Neither IND Distribution nor any of their subsidiaries or the sellers of the parts or systems make any representation that any of their parts or systems comply with any such laws.
EMISSIONS WARNING / California:
California laws prohibit the use of any aftermarket exhaust part or system that modifies, removes or replaces original equipment catalysts unless the California Air Resources Board (C.A.R.B.) has issued an Executive Order regarding such part or system or unless the part or system is exempted by being used only on racing vehicles on closed courses. IND Distribution nor any of their subsidiaries make any representation that any of their parts or systems has received such an Executive Order or that any of their parts or systems conform to the racing vehicles exemption. The purchasers are entirely responsible for informing themselves of applicable California laws and to comply with those laws.
