Hi, I'm after some advice about a rear and centre silencer i have just purchased for a friend. I've realised i've purchased (according to the details) the wrong ones and i've bought for a 1.4 and not a 1.4 16v. Realised as soon as i purchased but couldn't get the seller to cancel the order so now its on its way. What i want to know is there any difference in the exhaust parts? Will i be able to use them on a 1.4 16v 75bhp(that seems to be the difference according to other ads) or will i have to return and purchase again. Its for a failed m.o.t so only got 9 days now to play with. thanks for any advice in advance and hope it makes sense as i'm not mechanically minded at all.
