Janspeed is known the world over for performance-tuned, free-flow exhaust systems, producing Mild and Stainless Steel Sytems and Back Boxes for many different makes and models. Janspeed systems offer an increase in power and a deep performance exhaust note
Janspeed De-Catalyst Pipes
Through a forty year heritage producing performance components for road and track, from the early day’s fine tuning Mini Coopers to recently working on major projects for MG Rover and the Ford Motor Company, among touring car championships and 24 hour victories at Spa and the Nurburgring, Janspeed’s relationship with motorsport and tuning is special.
Manufactured using nothing but the highest grade (304) stainless steel or aluminised steel throughout production. All bends are mandrel formed to minimise loss of wall thickness and tube volume. To ensure a perfect fit they are hand made on individual jigs. All Janspeed stainless steel systems carry a life time guarantee and 18 months on the mild steel systems.
For the ultimate power increase, replacing the catalyst is a must. Janspeed’s sports catalysts are free flowing yet MOT legal (UK), while for pre August 1992 vehicles have a large range of straight through de-cat pipes.
