Test Pipes

BLOX Racing test pipes are constructed out of T304 stainless steel and are great alternatives for the restrictive factory catalytic converter.  Each test pipe is TIG-welded and features thick flanges and significantly increases exhaust flow.

The Honda test pipes feature slip-fit piping that offer adjustability and versatility in clocking angles. This unique feature helps accommodate the many different header lengths and collector angles that are currently on the market.  Test pipes are available in 2.25” and 2.5”.

3.0” test pipes are also available for Mitsubishi Evolution VIII and IX.
