The COBB Tuning Mitsubishi "Mid-Pipe" features a custom spun metal substrate high flow catalytic converter. This one piece 400 grade stainless steel cat has a much higher flow rate and longer lifespan compared to ceramic or "brick" style cats. It also reaches operating temperature faster than other style cats for cleaner cold-start emissions. An O2 sensor bung is located after the cat to be used by the second OEM O2 sensor. All tubing used in the fabrication of this mid-pipe is 304 stainless steel for increased corrosion resistance. The leading-end flange uses the stock donut gasket and factory spring bolts to aid in flex, longevity and proper fitment. This provides an improved seal compared to other methods, as well as reduced noise.

Note: Not compatible with factory Ralliart cat-back exhaust. A 3" aftermarket would be required.


The COBB Tuning Mitsubishi "Mid-Pipe" features a high-flow catalytic converter and is a direct bolt-in replacement for the restrictive factory unit. Made of 304 stainless steel with a 3" diameter, COBB's Mid-Pipe will work with the OEM exhaust, as well as any exhaust that is designed to keep the factory catalytic converter when installed on an EvoX.

Mitsubishi SS 3" Catted Mid-Pipe EVO X 2008-2015, Ralliart 2009-2015 is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Great Value, Sound Recently installed this catted mid pipe along with the Cobb downpipe. I was super impressed with the overall quality of the midpipe and the ease of installation. Cobb was smart enough to rotate the rear o2 sensor to the passenger side to eliminate a bracket and also prevent the o2 wiring from dragging. The overall sound of the exhaust with a full 3" turbo back exhaust on now is amazing. Not to loud, nice deep rumble. I have already put over 1000 miles on the car with this part without any issues.

Rated 4 out of 5 by from Not bad I'm satisfied with the overall product for my 2009 lancer ralliart. But I will say I'm a little upset about fitment. It's maybe half an inch to an inch short to connect to my exhaust and you basically have to stress and stretch it to tighten it down all the way, and the gaskets provided are just slightly to big.
