would this fit?

would a williams backbox fit on a mk1 1.4? if so would it make much difference to the standard 1.4 exhaust?
cheers

i'd have thought the piper bore going into the bx woud be different so would need a reducer.

Best thing you could do would be to de-cat it mate,and if it hasn't already got a straight through center section, fit one, my 1.2 had a straight through center.

You'll find a backbox will do almost **** all.

Also an induction kit with a valver bonnet is quite a good one
