E9X N54-N55 3.5″ Catback Exhaust Kit (Race Version)

Our 3.5″ Race Exhaust shaves about 56 lbs over the OEM exhaust due to our unique 2 to 1 design from the downpipes through the muffler. At idle, the race exhaust note is more aggressive and slightly louder than street exhaust version, which transforms into a deep, distinctive note at wide open throttle due to our use of a single 3.5″ primary. This race exhaust is loud. 

• Made from hand crafted, tig welded 3.5″ stainless steel.
• 100% 304 grade stainless steel construction.
• Gaskets & Clamps included.
