Profusion Turbo Flexi Pipe Coupler has been re-designed and developed specifically for Turbo and Hi-performance Hi-Torque engines. The build quality surpasses that of average repair flex pipes which are readily available today. Profusion Turbo Flexi pipes are engineered to relieve stress and thermal expansion due to high temperatures and vibration in a vehicles exhaust system. They will considerably reduce premature fracturing of Manifolds, flanges and other joints to avoid expensive repairs whilst prolonging the life of your exhaust system and components. A stainless steel exhaust system is a costly part of the vehicle, so insist on using only the Profusion Turbo Flexi and not a cheap repair flex pipe.
