been look around at sites and came across exhaust cut outs. would it be possible to use a cut
out before the cat and and run a bypass pipe past the cat and back to the main exit pipe.
saving time & money on de-cats or sports cats, would it still pass an m.o.t as the bypass can be closed
to run the cat, these seam very popular in the states.
has anyone done the same here in the uk ?????
here is a link New and Improved electric cut-outs are now available
