The Terrafirma range of ‘de-cat’ down pipes and silencer replacement pipes are intended to improve the performance and economy.  These pipes fit directly to the original system and require no modification. Remove the power restricting and vulnerable centre silencer and fit a Terrafirma free flowing silencer replacement pipe and enjoy the new throaty exhaust sound.
Made from 1.5mm 409 stainless steel these pipes will considerably outlast the life of the existing original system. 409 is easier to bend and weld and is not prone to cracking due to vibration like other grade of stainless steel.
