Special pricing! Free ground shipping! The Supersprint rear muffler for the E90 N52 models (325i, 328i, 330i) produces an enhanced version of the classic BMW inline-6 exhaust note. With a slightly raspy, ripping growl this exhaust produces a sound instantly recognizeable to any BMW enthusiast. This performance muffler replaces the stock muted part and opens up the exhaust for you to enjoy. This muffler is used with a Supersprint section 2 exhaust, most commonly with the resonator delete option and a set of connecting pipes to fit to the stock secondary cat section. That makes a it a full E90 cat-back exhaust.

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!

These N55 downpipes feature larger piping and catalytic converter that are freer-flowing than the original cats for better flow and less backpressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.

Features:

• 200cpi Catalytic Converter
• 100% perfect fit - CAD designed.
• less thermal load on the turbocharger
• more power by reducing back pressure
• significantly more torque
• Made from 1.4301 (SS304) Stainless Steel

For 2011 models, pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one..
