MAPerformance 11th Gen Honda Civic Si Catback Exhaust | Tech, Specs, & More!

MAPerformance Cat-Back Features & Benefits

The MAPerformance cat-back is built with 304 stainless steel and a mandrel bent design for superior performance and longevity. It includes dual wall tips, three exhaust tip options: polished steel, blue burnt titanium, and carbon fiber to fit the look you’ve been dreaming about. 

With Street and Race options, you can have the classic rich sound or open it up for race-inspired revving. This exhaust system hugs the bottom of the Civic Si, reducing risk of damage for drivers who want to lower their car, offering optimal build flexibility to fit your vision. Like other MAPerformance parts, there is a lifetime warranty for extended protection. Easy to install and designed to minimize exhaust drone, you’ll be out of the garage and on the road in no time.
