3" downpipe
I have a 3" decatted downpipe (bellmouth) in my shed and need to know is it worth fitting back on the car???
It was taken off for the mot and i had an over boost problem,but i think thats fixed now ,split in the boost pipe.
Can i fit this back on the car without getting a remap done(i have 98 wagon wrx and have been told you cant map that ecu)
Or should i sell it but have no idea how much its worth
