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 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 preference. 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!\u003cbr\u003e\u003cbr\u003eThis Supersprint Section 2 will replace and delete the factory resonator that sits before the muffler.

Manufactured from 304 stainless steel inside and out for superior resistance to corrosion as well as a significant reduction of weight. And from those aggressive looking ceramic-coated tips flows an exhaust note that will be music to the driving enthusiast's ears. The Dinan exhaust delivers exactly what the M3 owner demands in a performance muffler; increased power, reduced weight, a look that means business and the throaty exhaust note you'd expect from an M3.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2WD\/4WD: RWD\/AWD\u003c\/li\u003e\n\u003cli\u003e100% 304 Stainless Steel Construction\u003c\/li\u003e\n\u003cli\u003eGain of 7 HP \u0026amp; 5 lb\/ft TQ\u003c\/li\u003e\n\u003cli\u003eDrone Abatement Technologies\u003c\/li\u003e\n\u003cli\u003eStraight Through Exhaust Flow Design\u003c\/li\u003e\n\u003cli\u003e100% Bolt on Design\u003c\/li\u003e\n\u003cli\u003eLighter than stock\u003c\/li\u003e\n\u003cli\u003ePolished Tips\u003c\/li\u003e\n\u003cli\u003eCatalytic Converter Included: No\u003c\/li\u003e\n\u003cli\u003eExit Position: Rear\u003c\/li\u003e\n\u003cli\u003eHeat Shield Included: No\u003c\/li\u003e\n\u003cli\u003eMount Type: Factory mounts used\u003c\/li\u003e\n\u003cli\u003eMuffler Finish: Bright Brushed\u003c\/li\u003e\n\u003cli\u003eMuffler Material: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eMuffler Quantity: 1\u003c\/li\u003e\n\u003cli\u003eMuffler Shape: Rectangular\u003c\/li\u003e\n\u003cli\u003ePackage Quantity: 1\u003c\/li\u003e\n\u003cli\u003eSingle\/Dual: Single Exhaust\u003c\/li\u003e\n\u003cli\u003eSystem Type: Axle-back System\u003c\/li\u003e\n\u003cli\u003eTip Cut: Straight\u003c\/li\u003e\n\u003cli\u003eTip Diameter (in): 3\u003c\/li\u003e\n\u003cli\u003eTip Edge Style: Cut\u003c\/li\u003e\n\u003cli\u003eTip Finish: Polished\u003c\/li\u003e\n\u003cli\u003eTip Length (in): 6.25, 6.40\u003c\/li\u003e\n\u003cli\u003eTip Logo: Laser\u003c\/li\u003e\n\u003cli\u003eTip Material: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eTip Quantity: 4\u003c\/li\u003e\n\u003cli\u003eTip Shape: Round\u003c\/li\u003e\n\u003cli\u003eTip Style: Single wall\u003c\/li\u003e\n\u003cli\u003eTubing Diameter (in): 2.5\u003c\/li\u003e\n\u003cli\u003eTubing Material: 304 Stainless Steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp aria-setsize=\"0\" aria-posinset=\"0\" aria-level=\"0\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M3 E46 01-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":44528826810684,"sku":"D660-4604","price":1849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/3070\/1372\/products\/D660-4604.jpg?v=1677517475"},{"product_id":"superspring-exhaust-race-muffler-bmw-m3-e46-2001-2006-s54","title":"Supersprint Exhaust Race Muffler BMW M3 E46 2001-2006 S54","description":"\u003cp id=\"products_description\"\u003eThe crowning touch to an exotic and wicked sounding E46 M3! The Supersprint Race mufflers are very popular for the shriek they add to the S54's exhaust note. A full Supersprint system with these mufflers is one of the sexiest E46 M3 exhaust sounds we've come across - especially in a tunnel! The Lightweight Race mufflers are the capstone to that system. You can use them with any other center section or with the Supersprint section 2 (with or without a resonator).\u003cbr\u003e\u003cbr\u003eSupersprint 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!\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConnects to: Stock section 2 or Supersprint section 2\u003c\/li\u003e\n\u003cli\u003eTip style: 80mm quad round\u003c\/li\u003e\n\u003cli\u003eMaterial: T304 stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":44528829661500,"sku":"044006","price":2269.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/3070\/1372\/products\/Supersprint_044006_10.jpg?v=1677517592"},{"product_id":"supersprint-exhaust-sport-muffler-bmw-m3-e46-2001-2006-s54","title":"Supersprint Exhaust Sport Muffler BMW M3 E46 2001-2006 S54","description":"\u003cp id=\"products_description\"\u003e\u003cspan\u003eSuperSprint Sport Muffler Exhaust Quad Tip BMW E46 M3 01-05\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eAll Supersprint mufflers are of the flow through resonated design.
