Z4M Zaustworx Exhaust Backboxes Catback.


Reluctantly taking these beauties off my M. Custom made from Zaustworx in Burnley, they are gems!


So had these made by the guys at Zaustworx. Took a couple of visits to get them where I wanted but the results & the long drives were worth it for the 3 years I’ve owned them.


The sound is deep & raspy with cracks & burbles on overrun. There is a little drone around 2k rpm, they dialled it out as much as they could & did a great job! On startup it turns heads but in a good way & doesn’t at all sound like a boy racer’s car. The tone is the way the M should’ve sounded from factory.


The tips are a perfect size, IMO anyway, for the machine the M is, standard tips on our M’s are just no where near big enough. People always comment on how much better they look than a standard M.


Selling due to needing to free up funds for a garage build.


I paid £975 & that was just before covid, so to get these made now you’d be looking at comfortably north of £1100. With that in mind I think a fair ask is £500 for the pair. Willing to listen to sensible offers.


They’re still on the car at the moment so if you’re local to Guildford I’m more than happy to meet up, so you can have a listen before I take them off. Only going to remove them once I have a buyer lined up but this won’t delay a sale. I can have them off in a couple of hours.


If you want more pics or videos or have any questions don’t hesitate to drop me a message.


I am willing to post at buyers expense if that helps anyone.

Top fella Gaz at Zaustworx , he has done many bespoke jobs for myself on various motors , obsessed with quality , fit & finish .
Should make a great addition to any ZM
 
Thanks for the endorsement Mr Wilks. They were really professional getting the job done. Some garages make you feel like you’re asking too much when customising something like an exhaust but the guys at Zaustworx didn’t make me feel like that in the slightest. They listened to what I wanted & really delivered on the finished product. I’m sure if/when these come off I’m going to regret selling them.
 
Off topic but whereabouts in Guildford are you? Never seen your car about - it looks lovely!
 
Had a couple of enquiries about fitment. They are literally bolt on. Very simple DIY job. No welding or anything needed. 99% sure you’ll have the bits (bolts & O ring sealer between back boxes & mid section) you need on the standard exhaust you'll be taking off.

Yea sorry deleted it once I decided I was hanging on to them. Would like to say I’ll do another but seeing as they’re custom there isn’t much point.
