Thanks for the pics, golf is looking good  :happy2:

I see what you mean about the arch liners, dont think it will bother me too much...

Dropped my valance off today, slightly gave up with the smoothing over! They said they'll primer it and smooth it some more before spraying it. Asked for bottom half to be matte black, dunno if it'll look right  :confused:

Cos we know the owner, he's goona get my exhaust sorted and fitted too!  :happy2:

Might try out my camera skills in a mo...

Its ok :happy2:
When it comes to the centre section i would leave that as it is textured or have you already sanded it?
If you have sanded it matt black would look cool :happy2:

I did exactly this on my old GT TDI, I bought a GTI box on ebay they come up regulary as people always changing for aftermarket, from memory think I got it for ~ £50 in mint condition. Then I took off the old box and the mid section pipe. This needs to be laid next to the GTI box as the lengths are different (as are the pipe diameters) I cut the TDI mid section pipe to fit the GTI box and bought a reducer connector (from halfords I think, they are about a couple of quid or get one from your local kwik fit or similar) then the GTI box fits straight onto the TDI hangers, perfect fit, connected up with the reducer. I fitted the GTI valence (didn't paint it and jobs a good one. The sound was prefect as was the fit, quality, etc and best of all the price was really cheap.

Really good cheap mod, don't see the need for any expensive milltek back box (or similar manufacturer)..............

Hi, thanks for that info.

Few days ago, I dropped my gti valance off at my mate's garage to be primed/sparayed etc...
He told me to get hold of a reducer and clamps etc then he'd fit the back box for me when the valance was ready to go on...

Went to Southern Exhaust for starters, explained that I needed a reducer for Ed30->gttdi, asked for my reg. etc but they didn't have a clue about the sizes so were basically useless...
Went to TyreShops/Exhausts, again explained my situation, they lifted the car up... The bloke there had no idea either, said he'd only know if he cut and fitted it all there and then. I couldn't have it done tho cos valance not changed yet, so still got nowhere!
I asked in VW if they could tell me the pipe sizes, answer was no.

Told my mate that I had no luck, in the end he just said leave it to him and he'd do all of it at his garage(valance+exhaust), he couldn't believe it either that it was so much trouble just to get a reducer! I didn't think it would be this hard and cant understand why nobody seemed to know the size.
 
Dont suppose you can remember the size of the reducer you used? I'm not sure if the GTi exhaust and ED30 would be the same size anyway...

No sorry don't remember the size, I basically measured the new gti back box section and the old TDI section before I took the old exhaust of the car. I think the ed 30 is even wider than the gti.

It does look noticeably wider  :confused:

How did it sound when you had the gti back box on there, any different to before?
