Quad conversion on an already deleted backbox 3.0si

[nick_l]

I’ve been thinking a while about having a quad conversion on my 3.0si

It’s already got a backbox delete so sounds pretty mega as is, I just prefer the look of quads.

Finding a z4m bumper with pdc isn’t easy so I’m thinking about the option of cutting the existing bumper for the quad pipes. Anyone else done this? Will it look like turd?

Anyone got a quad/backbox deleted 3.0si I could have a listen to?

There's a company that offers a quad-setup and modifies the bumper:

Neither have PDC. I think OP isn't willing to drill/modify those bumpers himself. I'd be scared to drill into a £500 bumper too...

Yeah ideally I don’t want to be drilling for the pdc. I have looked at the mstyle quad offer, they’re 5 mins away from my house too. I’m guessing the price they have there is for 2 back boxes as well as the modified bumper....may be cheaper for just an extra pipe and modified bumper.

Hey mate, I’m re-thinking my own plans for the Zed so have a M rear in Titan :wink: Let me know if that’s of interest?

P.S. what happened to the front arches? Never heard back from you.

Re m style doing your exhaust, some time ago a forum member Jonny Essex I believe used the same company you way want to do a search

Not sure that PDC's on the short ass Z4 are worth bothering about. I disconnected mine within days of owning the car I think they are just a PITA :lol:
