Hardly used SuperSprint 'Racing' stainless steel rear Exhaust set (Left + Right) for the Z4M Coupe or Roadster.

No dents or any damage to the exhaust and tips (Diameter 70mm), complete with mounting rings and new U-clams.

Productnumber SuperSprint for reference: 044906 and 044936

Price fixed: Euro 595 (excl. p&p), new price was around Euro 1.200.

Reason for sale is that my gf. finds them too load on the Roadster (I like the full sound though ...) so I have to change to the SuperSprint Powerloops.

Can be collected near Amsterdam (NL) or send by UPS.

PM me for more information.

Did you ever have your car noise tested for track use with the fitted what dB were they?

I'm interested if Tom hasnt got there first! :lol:

They're fine for any track I've been to (anglesey, combe, brands hatch, silverstone, donington, goodwood, spa) so I'd say most circuits are fine with the possible exception of Thruxton (89db static), but I've been too scared of losing my day to find out! It seems to record anywhere between 89-94ishdB at 4.5k. I've also been concerned about low noise days at Donington as they use drive by rather than static meters, particularly on my induction side and again no problems.

That said, these sound pretty loud in the car so be prepared for that, to the point that I don't really hear the induction anymore!
Super light too, I'm only buying these to replace my slightly scruffy ones, so you'd be welcome to those should you wish, for less $ obviously :)

Haven't heard from the OP so maybe they've been sold already :|

Thanks for the feedback Tom really appreciate it! Pm me what you want for yours - might end up that if we met up to exchange parts instead of sending them you'd get your spoiler more quickly :lol:
 
Let's see if I get a reply, will be in touch.
Bare in mind my exhaust system to the back boxes is totally standard, so if you have any modified parts in there then you can disregard my comments as they are unlikely to be relevant any more!

Il agree with the pretty loud ( id probably use other adjectives but i won't spoil the sellers thread ) but " super light " :?
I removed & sold a pair of these off a ZMR , unless different versions of them are available they were not much different in weight handling them to oe stock boxes .
By comparison the BCS boxes i fitted were around 50% of the weight

Are we talking about the same things here? Not the 'power valve' version?
I haven't had both on the scales but I'd say the race versions are at least 1/3rd weight of the oem ones.
Will check at some point!

i'm not clued up re different versions of these Tom , pretty sure they were stamped "race" or "racing" on the boxes .

If they weren't fakes then they must be the powerloop versions which do weigh pretty much as stock, about 9.5kg for the powerloop.
The race version is significantly lighter and cheaper (the powerloops go for about €1000 a side new) :o
I have the stockers at home so will get them on the scales, but for sure there's a huge difference between the two :?

Nice one Tom cheers! Yeah mine has a supersprint manifold and sports cats, standard xpipe and back boxes though so these/yours should fit mine just fine 8)

Oh sure they'll fit, but the dB levels may well change if you modify the cats for instance was what I was trying to say.
I'm super intrigued about the headers (manifold)... it was my understanding they didn't do them in rhd for these cars. Love to see a pic or part number, cheers.
 
Aah right I understand now :lol: well hopefully it'll be OK.... If not I can always bung the oem cans on for trackdays...!

Ill try and grab some photos when I can - it's tucked away in the garage at the moment whilst I'm doing all the decorating in the house - it'll be out late Feb I think... :roll:
 
Sorry, exhaust is just sold and will be fitted to a Z4MC. My experience - as I have both versions Race and Powerloop - is that the Race is loud and perfect for tunnels but drones in the cabin, further adjustments as aftermarket x-pipe and/or cat replacement will make it too loud. The powerloops give a bit more sound but more important less drone than the Race and the combination with a SS x-pipe and cat pipe is perfect but cost twice as the Race.
 
Thanks for the feedback Mare - looks like I'd be better looking at quieter back boxes in that case - I'd kick myself for pitching up to a trackday only to fail noise limits.

Cheers
