Want a straight through pipe on my corsa and was wondering what is the best way to go about it? Where to get pipe if i was going to diy it or how much would it be to get it done professionally? Cheers.. Ps i already got a backbox so wont be needing another

you can buy centre race tubes and de-cats of ebay mate, orr just cut them out and replace them with tubes, but then what happens when you come to get an MOT.
