PRL Motorsports 3" Street Downpipe / Front Pipe Combo 2016+ Honda Civic 1.5T MT / CVT
Testing is showing that a downpipe upgrade is one of the most effective modifications to perform when looking increase power out of Honda's 1.5L turbo engine. PRL decided to take these findings one step further by upgrading the restrictive factory A-pipe that bottlenecks exhaust flow with a typical downpipe upgrade.
The PRL downpipe / front pipe assembly is constructed of mandrel bent 16 gauge 304 stainless tubing and 304 stainless 3D CNC'd flanges with smooth transitions for optimal flow and fitment. All pieces are fully back-purged for weld integrity and optimal strength while the front pipe features a high quality, reinforced stainless flex section. Customers can run an aftermarket exhaust or mate our combo to the factory exhaust with the optional stock exhaust adapter. Choose between catless or 300 CEL cat. There will not be a way to offer a guarantee that the cat will keep CELs off unless users turn it off via KTuner or until Hondata offers any sort of support.
All kits will include gaskets, stainless hardware and components needed for a seamless installation.
PRL tested the catted version on their CVT shop car and 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 the PRL catted downpipe and front pipe (red line), and the same car with the PRL 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.
Catted Downpipe + Front Pipe Gains WITHOUT Tuning on Our CVT Car:
- 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
