    Considering sticking a 4-2-1 Manifold on my car now its passed its M.O.T and was just wondering if you guys can post a few of your videos up of your system before and after the De-Cat was put on, current system on mine is: Supersprint Race Centre Section / 3 Inch Ashley Competition Backbox.

    Kind regards, Richard .

    cant really say i video's mine before, but when i decatted it, its was considerably noticable, in performance, sound and fuel economy after decating i added 4-2-1 but didnt notice any sound difference, put same for perfomance and fuel. i get 25mpg.
