Up for sale are as the title says . I bought these recently but after doing some motorway driving and long drives on the NC500 I have decided they are not for me . This is mainly due to the fact that I have no resonators and running 100 cell cats so they are just too loud for long journeys but I`m sure they would be fine on a standard set up . They will be available in about a weeks time .

The recent for sale advert I bought them from is here https://z4-forum.com/forum/viewtopic.php?t=148497

I am asking 950 pounds . I am based in North Shropshire .
 
Will leave this on Forum for a couple of weeks and then will put on eBay etc .
 
Pics and vids may help? Plus any gratuitous pics of the MC always welcome!😃 Glwts

Yes will have some pics by end of week as they should be off car by then but won`t have changed much since I bought them from previous seller as shown in link to previous sale as they have only been on car to do the NC500. Cheers :thumbsup:

I’ll happily buy your 100 cell cats so you can keep running this set up :)

They are indeed and a good price I think considering how much they are new :thumbsup: Open to reasonable offers before they go on eBay .
 
You want me to pop up a video of mine with an in-car Rode Mic on my last trackday, to give a feel for the sound in-car (my exhaust is exactly the same as this, so basically everything for sale here just slapped onto the standard cats....)
 
Ignore my mate and I chatting bobbins - key point is there's a period of idle and low rpm in the pits, some high rpm stuff on track and then some medium/low stuff whilst pottering bsck to the pits under red flag - along with some chat at points so prospective buyers can gauge the relative volume of the exhaust against the volume of the voices:lol:

That looked great fun Ed. At first, I could understand why you were always in a higher gear than I would expect, then I remembered you have a shorter final drive. Do you find it makes a significant difference on track?

Always a hoot, first outing of 2024 so not the fastest but just chuffed at how good the car felt 8)
I really rate the 4.1 upgrade - it definitely feels like you can keep the engine on the boil better, and it does feel puncher I reckon. I think the 4.1 is a nice balance between oe and the full on 4.4, I wouldn't want to go shorter than 4.1 for ring trips personally!
 
I’ll have to look into how practical it would be to fit a shorter final drive here. Unfortunately, difficult to arrange and unreasonably expensive are the answers to most such enquiries!
