Testing shows that a downpipe upgrade is one of the most effective modifications to perform when looking to 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 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. Pair this with our 3" Front Pipe piece for optimal exhaust flow and performance!
All kits will include gaskets, stainless hardware, and components needed for a seamless installation.
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
