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

Our 3.5″ Street Exhaust shaves about 42 lbs over the OEM exhaust due to our unique 2 to 1 design from the downpipes through the muffler. At idle, the street muffler’s exhaust note is subtle and slightly louder than stock which transforms into a deep, distinctive note at wide open throttle due to our use of a single 3.5″ primary.

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