Our testpipes are built to extremely high standards, with high quality materials: laser cut heavy duty flanges, all mandrel bends, and fully tig welded; for great fitment, strength, and flow.
Knowing the kind of abuse lowered cars with 3 inch exhaust generally see we only use 0.63" stainless tubing unlike some thinner products on the market, our test pipes are built to last.
Wide band bungs are installed on each pipe in a clean and safe location pointing up towards the transmission rather than down towards the ground, you won't have to worry about damaging your expensive wideband sensors on potential road hazards.
