Perrin Downpipe with High Flow Cats Mitsubishi EVO X 08+
The PERRIN Performance downpipe is the perfect compliment to your PERRIN EVO X catback exhaust . This system combines to make an 3" Turbo back exhaust system.
Like Perrin's other exhausts, the EVO 10 downpipe w/cat is built with 3" 304 Stainless Steel tubing, which passes through a special high flow 200 cell per inch metallic catalytic converter. All mirror polished for that show look. The downpipe does add a little sound to an stock exhaust and great gain in horsepower.
Another great feature of the PERRIN Downpipe the weight savings! Perrin combined 2 OEM parts to make the PERRIN downpipe which helps with the savings! The OEM downpipe and catpipe weighs 19.85lbs and the PERRIN Downpipe w/cat weighs 8.8lbs. That is a huge savings of 11lbs!
Below is a link to some testing Perrin did with both the downpipe and the catback exhaust. The first part is showing the catback exhaust then the downpipe was done later.
CLICK HERE Perrin saw 20WHP in some parts of the RPM band, and a pretty good average of about 10WHP. One really cool thing, as expected, was the turbo spooling a little quicker. This made for about 50ft-lbs of torque gained at 3000RPM. The above link is to the graph showing the Perrin Stage 1 ECU flash with nothing changed but the catback exhaust.
Next Perrin left the Catback on along with their Stage 1 flash and as quick as they could Perrin bolted on the 3" downpipe with 3" high flow cat pipe. The most interesting thing is peak power didn't change much nor did peak torque. But the power was much more smoothed out, and much broader power gains were had. Meaning, Perrin still got 20WHP, but as you can see below the area of 15-20WHP gained was much larger. Below is a link to the graph showing Stage 1 with no exahust versus Stage 1 with both PERRIN catback and Downpipe.
CLICK HEREThe Perrin Downpipe is a simple bolt on item, that requires, nothing more than simple hand tools to install. No need to trim the bumper, bend a bracket, or anything. Literally unbolt the OEM system and bolt the PERRIN one in its place.
