Headers are a bolt-on component that will make a huge improvement in how your BMW performs. As a replacement for your factory BMW exhaust manifold, our BMW headers provide a more direct path for exhaust gasses leaving your engine. Headers prevent your BMW's exhaust pulses from "fighting" one another as they leave the head. The end result is that BMW headers give you more power and torque, and you'll love the high-winding top end push that a free-breathing engine exhibits. BMW headers are a must-have if you're doing any engine modifications on your vehicle. Along with a cold air intake, BMW headers provide the free-flowing exhaust necessary to get the most power out of your motor.

E46 M3 Headers
(more info) These high quality headers are a direct bolt on for the US BMW E46 M3 and deliver an impressive boost in power over the stock manifolds by removing the restrictive catalytic converters. In our testing for our own E46 M3 Grand Am race cars, we've found the US S54 engine simply needs a good set of headers to make better power. For years, we've been using the factory BMW Euro headers to give the US E46 M3 a big boost in power. Recently the factory headers have jumped up in price from BMW, opening the door for a lower cost alternative -- and these are them! These aftermarket coated headers accomplish the same goal and save you big money over the Euro M3 headers. Pulse-tuned length ensures maximum exhaust flow, while a dual-stage thermobaric ceramic coating lowers radiated heat temperatures by up to 65% as well as increasing the exhaust scavenging effect and reducing corrosion. Headers come ready to be installed, and include new manifold gaskets, exhaust crush/seal rings, as well as loctite thread sealant.
If you're adding these headers to your M3 or MZ3 (with S54 engine) than we highly reccomend also purchasing the Shark Injector Race software - tuned for headers and no cats. An extra power boost, quicker throttle response, no top speed governor, and no Check Engine Light!
Since this upgrade removes all of the catalytic converters, it is intended for off-road use only. A waiver is required before items can ship,

Factory Euro Header Upgrade for E46 M3 2001-2006
(more info) BMW factory headers from the Euro market E46 M3 replace your stock manifolds and eliminate your catalytic converters for a big power boost. The Euro M3 had an extra 11hp and 17ft-lbs of torque over the US M3 and most of that is in the
headers. We've tested a lot of headers for the E46 M3 for our Grand-Am racecars and the Euro headers consistently come out on top. These are a direct bolt-on to your engine and will fit with almost any center section. They are a perfect fit with none of the haggling and quality problems of imitation headers. (Left Hand Drive Models Only) Buy this package and the gaskets and hardware are free!
Also included with this upgrade is the Shark Injector Race software - tuned for headers and no cats. An extra power boost, quicker throttle response, no top speed governor, and no Check Engine Light!

Supersprint Race Header/No-Cat Exhaust System for MZ3 (S52)
(more info) Supersprint offers a header/no-cat upgrade for track cars that is heads and
tails above the competition. Using the larger sport headers for the Euro-market
M3, and a straight-through Euro center resonator, big horsepower gains can be
had from the S52 engine in the 1998-2000 M Coupe, M Roadster. This system will
delete your cats so it's intended for track cars only and special software will
be needed to keep the check engine light off. This exhaust system is a perfect
compliment to our Intake/Cam
Packages (link) and we have special software for running headers and no
cats with the intake/cam packages. All gaskets and hardware are included. Note: this is a special-order item
but worth the wait! (Left Hand Drive Models Only)
