Probably more annoyed that I've just been walking around with my new mavic pro drone in follow me mode 😆

So... is secondary cat deletion a service you can offer Aswell as the backbox modding for the Si?

If so how much are we talking, it's a great engine it just needs to be more vocal with cracks and pops and I think this does it perfectly!
Z4 now sold :(

Yes, I can do it - However, if doing again, I would not attempt to disturb the HORRENDOUS downpipe to exhaust joint as I did on mine, but would use 2 of the same sleeves I fit the backboxes with.

Let me see if "my man" has a spare set of Si cats, so I could have one ready made - Cost wise, I'd say an extra £200, which is there or thereabouts what an exhaust place would charge for cutting out the originals and welding in plain tube. The problem with that, is if an MOT tester realises the original secondaries have been removed, it could be an MOT fail. The way I do it, the car remains completely standard looking from underneath as I take off the heat shields, cut a hole in the top side and remove the guts, before welding them up and refitting the shields.

Apologies if I've misread somewhere, but do your videos include a back box mod aswell or just the cats?

This sounds awesome, very impressed by your handiwork! Might have to start saving up and getting you to make mine sound this good! :D
