Injen Axle Back For 2012+ Civic Si
(60mm Pipe w/3" Tip)
MSRP $420
SES1579

Injen has always been great at getting maximum airflow into your motor. Now they have turned their attention to making exhaust systems to match that increased airflow for power gains across the RPM range of your Civic! Starting with 304 stainless steel each system is computer assembled from bending, to CNC'd flanges, through final assembly welding. This guarantees a great fit and consistent performance from every system. The Super SES exhaust systems utilize a flow through muffler for maximum power and an aggressive tone. Finally each exhaust is finished off with Injen's embossed flared tip design for show stopping looks to compliment the additional power.

Skunk2 MegaPower Catback Exhaust (Coupe SI)
76mm Piping
MSRP $600
413-05-6050








A properly designed exhaust system is critical to engine performance. Skunk2’s 76mm MegaPower RR Exhaust system for the 2012 Civic Si coupe was developed with this in mind and is based off of more than 15 years’ worth of racing experience. Dyno-proven for maximum horsepower, MegaPower RR systems are constructed of T-304 stainless steel, are robotically TIG welded, and feature CNC mandrel bends for a precise fit. The MegaPower RR for the 2012 Civic Si in conjunction with the Skunk2 Alpha Header for the 2012 Civic Si has seen hp gains above 30hp.

Designed for heavily modified naturally aspirated engines as well as for turbocharged applications that require more exhaust flow than Skunk2’s 70mm MegaPower R Exhausts provide, MegaPower RR Exhausts allow engines to breathe more efficiently and produce more power thanks to larger diameter piping. MegaPower RR Exhaust systems were designed for maximum flow and power, featuring oversized tubing and mufflers, which result in a significantly louder tone when compared to other MegaPower systems.

from a previous post of his -
...So the set up I will have is: U.R. 3" exhaust w/ the 2nd muffler option (instead of a resonator it's an additional muffler, so kinda like a single sided dual muffler if that makes sense) mated with a U.R. 3" DP w/ no cat option. Should sound loud BUT clean with the extra muffler on there.
