So, we finally got around to testing the catted version on our CVT shop car. The results were rather impressive!
Listed below is a dyno graph depicting a bone stock 1.5T CVT dyno without a flash (blue line), the same car with our catted downpipe and front pipe (red line), and the same car with our catted downpipe, front pipe and Hondata's +6 PSI reflash (green line). Peak torque came in about 400 RPM sooner than with the factory cat and the car picked up massive amounts of bottom end power, over 40 whp and 50 ft/lbs of tq to be exact, at about 4300 RPM. Peak gains were 10 whp and 14 ft/lbs tq while these gains held true throughout the entire power-band, with over 20 ft/lbs tq gains up top.
We initially expected similar gains from the catless version, but these catted results blew us out of the water. We can't wait to see what sort of gains we will see from the catless version once Vit tests both versions on his 6MT car.
Catted Downpipe + Front Pipe Gains WITHOUT Tuning:
400 RPM increase in peak torque
40+ hp and 50+ ft/lbs tq down low
10 hp and 14 ft/lbs tq at peak
10 hp and 14-20+ ft/lbs tq throughout mid-range/top
