hi, i've got a mk2 astra gte 8v and fancy a custom exhaust.
i've seen quite a few mk2's with twin backbox's (one each side), and would like it on mine.
how though do u fit them, do u have to modify anything (wheel well, rear tow hook, fuel pump etc??) if so how do u do it, where do u put things
any1 had this done, what sort of price would i expect 2 pay, i'm thinking about £400?
