Many of our customers compete in sanctioned competition events where ever last bit of performance is critical.
Other customers are avid off road enthusists and need ever last bit of ground clearence. On the new FJ Crusier and Tacoma 4x4, Toyota really chose to run the stock Y pipe under the transfer case where it gets hung up on every stump and rock on the trail. These alternative Y pipes solve this problem!
Test Pips are not to be used on a public road in the state of California - not CARB approved -
