Have a Zip SP50 std exhaust (H20 model)and have seen them offered on ebay as derestricted. Whats involved or are they derestricted as standard TY
They are crap buy design ,buy another pipe and keep the one you have as a spare One of the pipes goes to a air intake one way breather ,this sucks in fresh air for two reasons ,one is to pass imisions and if the pipe is fitted with a cat it also helps it from over heating and burning out the cat ,but they are still crap by the designe of the pipe
