MAP Catback Exhaust | 2017-2021 Honda Civic Si COUPE ONLY (HDAX-CBE-CPE)

MAP Catback Exhaust | 2017-2021 Honda Civic Si COUPE ONLY (HDAX-CBE-CPE)

MAPerformance designed the HDAX-CBE-CPE catback for the 10th-generation Civic Si coupe after asking owners what they wanted from an aftermarket exhaust. It uses 3-inch 304 stainless tubing bent in-house, with each bend measured and each system test-fitted on jigs before the welds are inspected. Buyers pick the sound with a Street tip section, which is quieter and avoids drone on the highway, or a Race section, a straight pipe to the quad tips that is the loudest and slightly raspier option.

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

What's included

• 1 MAP Civic X catback front connection
• 1 resonated mid-pipe front section
• 1 resonated mid-pipe rear section
• 1 exhaust tip section (Street or Race)
• 2 3" V-band clamps
• 1 3" 3-bolt gasket
• 1 3" slip-fit exhaust clamp
