Injen SES1835TT-1 60 mm Cat-Back Exhaust System with 4" Burnt and Rolled Titanium Tip for Lancer 2.0L 4 Cylinder/Lancer 2.4L

Sounds great, however I may have gotten some faulty gaskets with mine, no more than 6 months after the install the gasket in the middle just after the high flow cat failed, and now the the rear gasket is junk, so now I'm on the hunt for gaskets that fit. I work out of town most of the week so my time is limited to tinker and play with my car.

Perfect, barely heard when cruising but louder when you step on it...only 4 stars because it was missing a gasket. Will throw a CEL for your downstream o2. Trying out the $5 fix and will repost if it worked on my 2010 gts 2.4 mivec, also get a felpro 61106 gasket for your manifold.

Sounds amazing has a very nice rumble when you are just driving around sounds even better when you get on it. Came with all of the parts and gaskets that are needed. It will throw a code but asked around and it is nothing to worry about.
