This Combo Kit includes 

  • 3" Downpipe & Front Pipe
  • Ktuner Flash V1/V2

The wait is finally over, we are now introducing the first full 3" (76mm) downpipe / front pipe assembly on the market.


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. We decided to take these findings one step further by upgrading the restrictive factory A-pipe that bottlenecks exhaust flow with a typical downpipe upgrade.

Our 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.

We tested the catted version on our 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 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. Scroll down to see Vit's results with our catless version on his 6MT car!

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

We are currently offering two research calibrations with more to come in the future. Both can be ran with 87 octane fuel, but running 91+ will give the best results.
Stage 0 (CVT):
Improved throttle response
Reduced turbo lag
Improved low-end and midrange torque
Smoothed boost curve, 15psi
Producing a much more sporty feel and drivability

Stage 1 (CVT and MT):
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Reduced turbo lag
Improved low-end and midrange torque
Boost raised to 18psi
Producing a much more sporty feel, drivability, and additional top end power!
