Presenting the COBB 3” SS Quad-Tip Cat Back Exhaust
for the Mistubishi EVO X. This direct replacement cat back exhaust
boasts 304 stainless steel construction, a custom high-flow
straight-through muffler design and impressive exhaust note.
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.
Exhaust gasses are guided through 3-inch diameter tubing into the center
inlet of the 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 COBB emblazoned 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 below:
 
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.
