Akrapovic Exhaust
The Akrapovic (pronounced "Ack-rap'-o-vich") company was founded in 1990, based on the experience gained in the field of motorcycle tuning by Igor Akrapovic. Akrapovic is now the leading supplier of Titanium exhaust systems for cars and motorcycles, and are known internationally for their quality and performance. Akrapovic supplies exhausts to BMW Motorsport for racing applications such as the M3 GT4, BMW Motorrad, and many professional race organizations campaigning BMWs and Porsches. The titanium Akrapovic uses for their exhaust systems is produced exclusively for them. Their Titanium is three times stronger and more heat resistant than any other titanium product on the market, in addition to being 40% lighter than stainless steel. This high strength allows the use of thinner insulation while still achieving the highest quality standards, bringing decisive advantages both on and off the race track. The Akrapovic exhaust systems are the lightest and highest quality exhausts you can buy for a BMW. And as you'll find from their sound clips, they also have an amazing sound quality.
Borla Cat-Back Exhausts
We have been selling Borla exhausts for BMWs for over 10 years and it is still our Number 1 choice for a cat-back exhaust. Borla designs their exhausts to be not too loud (you don't own a Camaro) and not too quiet (you don't want to drive a hearse either) but rather in the middle. If you're driving with the windows up and the radio on you probably won't hear the great sound. Borla also builds their exhausts from T-304 stainless steel (inside and outside). This means long life (a 1,000,000 mile warranty is part of the deal) and light weight. Comparisons between a stock E36 M3 muffler and the Borla revealed the Borla system is 26lbs lighter!
UUC / Corsa Performance Exhaust
CORSA is one of the largest automotive and high-end marine exhaust tuning companies in the USA with engineering and manufacturing facilities in Ohio and a patented, proprietary technology called Reflective Sound Cancellation™ (RSC, for short). CORSA consults to General Motors, Ford and Daimler-Chrysler and carries the title of "official licensed product" on its GM aftermarket exhaust systems.
The result of the UUC and CORSA's partnership and extensive research and development on the BMW 3 and 5 Series, is the new dronefree RSC™ exhaust system, delivering a pleasant sound at idle and cruise, and a muscular roar at high rpm. CORSA tuned this system specifically to counter drone. Sound pressure waves are reflected within the muffler case and unwanted noise frequencies are cancelled through patented Refective Sound Cancellation™ technology. Their straight-through design coupled with RSC™ noise cancellation technology allows them to tune out the undesirable low frequencies that cause droning, while reducing back pressure. A reduction in back pressure allows the engine to produce more horsepower and torque. The end result is a tuned muffler that produces the best sound and performance possible.

Supersprint Exhaust Systems
Description: Supersprint Inc. was formed in 1955 with the objective of designing and building the highest quality exhaust systems in the world. That objective has been the driving force behind each Supersprint product from the first system built to those being developed for the future. When you purchase a Supersprint product you can be assured it is the highest quality available. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's exclusive in-house Maha 4-wheel chassis dynamometer. When compared to a domestic stainless system, the Supersprint Stainless system showed a 30% flow improvement over the Factory M3 system. To protect against corrosion each non-stainless system receives an aluminized coating inside and out. All internal tubing, resonators and tail pipes are stainless steel. Packing material is longstrand stainless steel wool and rockwool. TÜV Approved.
Headers
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.
Catalytic Converters
Same quality construction as OEM but at a third of the cost. No welding required because these bolt on to your stock exhaust manifold and muffler. Meets all EPA and CARB requirements. A factory warranty is included: 2 year/25,000 on internals, and 5 years/50,000 miles on exterior shell.
Oxygen Sensors (O2 Sensors)
Every new BMW, and all BMW cars made from 1980 on, have an oxygen sensor, often called an "O2 sensor". The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to by simply changing your oxygen sensor today. We carry Bosch oxygen sensors, and in some cases Genuine BMW oxygen sensors or OEM oxygen sensors.
