If you referring to the ones here then yes, you have twin pipes coming down to the rear box, the ones pictured here are twin boxes with one inlet. So each box would connect to one of the pipes coming down from the engine manifold and to the back.
Snoop D said:hi, im new to all this. Luckily this came up on the homepage when I was having a little scroll. do you know if these would fit a 3.0i model? will they need to be massively modified to fit the car? as i can get a local exhaust shop to fit them - do you know how much i should expect to pay to fit these. the z4 currently has no exhaust, its nice and deep but annoying on long journeys. hopefully this can be the right balance between stock and no backbox? u have any vids of the sound?
sorry for all the newbie questions but i just want to be sure first. cheers![]()

Perhaps you could reply to my messages about the Aero Skirts I have bought off you and paid 300GBP into your account before arranging to buy parts off others. 4 weeks since I paid you the money, multiple private messages and emails and still I am waiting for a simple phone number for our freight company to contact you.......
Sorry for the delay. I have responded to your PM's - please refer.
As previously stated, I have checked the last 5 weeks and you have not sent 300 and it has not been used for 'arranging to buy from others' as you suggested. Your courier knows my e-mail address and could have at least tried to contact me this way if all else failed.
If 300 ever does get transferred into my account, you can have it straight back.
Thanks.

If for some VERY strange reason you didnt recieve the money then leaving it 4 weeks to tell me this is hardly kosher either. Very concerned.
To the others on this thread I apologise for 'busting in' on it, but the lack of responses and replies from Aeroadster left me with little choice.

Nope, account number was right and 300 was not transferred. The screenshot you sent says it is submitted for processing - not confirmation that payment has been successfully made...
I gave you the reason for not paying with PayPal and you agreed. If you are uncomfortable with not paying with paypal, then you should of thought of this before wanting to buy - this is your problem not mine. I have not left it for 4 weeks and I did advise you of my circumstances at the time...
I will contact the banks tomorrow tell them of whats happened. You can have your 300 straight back if it does make its appearance.
Thanks, and sorry to the other members for invading this space.
Cheers.
