Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Sound + Power + Quality = the ultimate exhaust upgrade for the E46 M3. The Supersprint Race exhaust has a lot of fans, us included, with the mufflers producing an intoxicating shriek. This system covers the entire E46 M3 exhaust - headers, section 1, section 2, and rear mufflers with special discounted pricing. Although sound is subjective we feel the full Supersprint system produces the sexiest, most thrilling exhaust sound. It's an exotic, European-type sound unlike most American-made rumbling exhausts and it blends perfectly with the technical sophistication present throughout the E46 M3. This system does not diminsh the rasp inherent to the S54 but it's a refined and tuned sound that has won over many fans. And it's not all about the sound. Full system details:

• Stepped Headers - replaces factory manifolds and cats; equal length stainless tube in increasing stepped sizing
• Section 1 - matching stepped sizing straight pipes or metallic catalytic converters
• Section 2 - with or without resonator cross-over pipe
• Mufflers - Lightweight Race mufflers
  
• Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!
