Significant attention was devoted to the packaging of this exhaust. Tubing diameter was increased to 3" and bends were kept to a minimum with large radii for optimum flow characteristics. Fitment was extensively worked to ensure maximum ground clearance to accommodate cars with very low ride heights. Designed as a direct replacement for the factory cat back exhaust, it uses all of the stock mounting points and is compatible with the factory cat pipe as well as the previously released COBB High Flow Cat Pipe.
COBB 3" SS Downpipe - Widened 3" mandrel-bent stainless steel downpipe
COBB 3" SS Testpipe - High-flow catalytic converter for optimal exhaust flow
COBB 3" SS Quad-Tip Catback Exhaust - Beautiful fabrication and awesome rumble
3" Stainless Steel Downpipe
The COBB Tuning Mitsubishi EVO X Downpipe features a widened diameter of 3" for increased flow of exhaust gases from the turbo charger to allow for improved horsepower and torque. The downpipe is constructed of 304 stainless steel, mandrel bent tubing, which can be fitted to the OEM exhaust or the COBB Tuning EVO X Test Pipe. The trailing-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.
3" Stainless Steel Testpipe
The COBB Tuning Mitsubishi EVO X "Test 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 downpipe 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.
3" Stainless Steel Quad-Tip Catback
Exhaust gasses are guided through 3-inch diameter tubing into the center inlet of the fully-24-inch wide muffler section. Internal to the muffler, the exhaust gasses pass through a reversed Y merge, efficiently splitting the exhaust into separate muffling chambers on each side of the canister. 2.5-inch outlets emerge symmetrically from each side of the canister and direct the exhaust out the rear through quad polished exhaust tips. This straight-through exhaust design is much more effective at reducing exhaust back-pressure as can be seen in the illustrations.
304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip. Perfect fitment is achieved with either the Subaru factory downpipe or the COBB 3" SS Downpipe.
Potent performance need not attract the attention of over-zealous law enforcement. Despite the superior flow characteristics of the COBB EVO X Cat Back exhaust, it still conforms to strict SAE sound emission requirements of 95 decibels, even when paired with the COBB EVO X Downpipe and COBB EVO X Cat Pipe. The quad round tips are the maximum diameter that can be used with the factory diffuser. No diffuser or bumper modification is necessary with this catback.
The COBB 3" Quad-Tip SS Cat Back Exhaust for the EVO X offers unmatched performance, OEM fitment, innovative engineering and outstanding craftsmanship.
