MAP Catback Exhaust | 2017-2021 Honda Civic Si SEDAN ONLY (HDAX-CBE-SN)

MAP Catback Exhaust | 2017-2021 Honda Civic Si SEDAN ONLY (HDAX-CBE-SN)

The HDAX-CBE-SN is MAPerformance's catback for the 10th-generation Honda Civic Si sedan. It is built from 3-inch 304 stainless steel tubing that MAP mandrel bends and checks in-house, then fits on custom jigs and inspects weld by weld. Every system has a resonated mid-section, and the owner chooses between a Street tip section that keeps highway drone in check or a Race section that runs straight pipe to the quad tips for the most volume.

Key features

• 3" 304 stainless steel tubing, mandrel bent in-house
• Long mid-pipe legs formed on a CNC mandrel bender to cut down on welded joints
• Single resonated mid-section with polished 304 stainless mufflers
• Quad staggered 3" tips, single or dual wall, polished or burnt blue
• Street or Race tip section, swapped at a single 3" V-band joint
• Can do away with the factory 3-bolt joints at the front of the catback and rear of the front pipe
• Routed with ground clearance in mind for lowered cars
• Multiple connection points for stock or upgraded front piping

Before you order

Fits 2017-2021 Honda Civic Si sedan only; the coupe needs HDAX-CBE-CPE. MAP lists the Street version at 39 lbs and the Race version at 34 lbs, against 43 lbs for the stock system. The supplied 3-bolt gasket is for factory front pipes only. Clean burnt blue tips with water and, if necessary, a gentle soap only, since abrasive cleaning removes the heat-treated finish. Send us your year, model and current setup and we will confirm fitment before you order.
