Version 2 allows users to retain the factory heat shield with our full 3" (76mm) downpipe.
Research and testing show 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 16 gauge 304 stainless tubing and 304 stainless cast ends with smooth transitions internally for optimal flow and fitment. Exhaust pieces are fully back-purged on site for weld integrity and optimal strength. Pair this with our 3" Front Pipe piece for maximum exhaust flow and performance! Choose between catless or 300 CEL cat. There will not be a way to guarantee no CEL codes unless users turn it off via KTuner or Hondata. To follow suit with most PRL products no cutting, trimming or other modifications will need to be done. All kits will include gaskets, stainless hardware, and components needed for a seamless installation.
