Has anyone done (or know of) a setup like on the modern M3/M5 where you have 4 exhasts out the back ??  Would like to do something like that, but dont know where to start !

give your local http://www.powerflowexhausts.net/ - PowerFlow place a bell, they do bespoke dual and quad-exit systems, i've personally had two systems done by my local franchise ( http://www.turrifftyres.co.uk/ - Turriff Tyres ) and highly recommend them

Hi Zeeny99999 - i am selling made to spec quad exhausts so send me your email and i'll send over some pics, specs and price etc....

Cheers - if i can get enough interest through the car club then a discounted group buy may be on offer.......

Here is a pic of my 523iSE with it done......

This is the system before it is powder coated so you can see how it is manufactured.

Yeah, looks quite intersting, how much did the system from PoweFlow set you back Stephen ?
 
Dave, your system looks good in the picture from behind !  How do the M3/5's do it as does having so many split's into two cause a increase back pressure?  Looks the nuts.  How much for a 540 ? E34

£280 for a single system, double that if you want a quad

The one in the pic is only for E39s and i can deliver them to your door with all brackets and fittings for --edited--. Just need a competent fitter to pop it on. Let me know if there is any interest.....

Please don't publish prices on the forum.

I had an exhaust made by Jullian/TT on my MR2 but I'm not sure if I would get one on the BMW.  I don't think the quality of steel used is that great but I guess you get what you pay for.  Still don't fancy paying £500+ for an Eisenmann back box though!

Did he quote you £280 for the E39 and was that back box only?  Sorry for the thread hi-jack by the way.

a cat back system on the e36 meant pretty much backbox only due to the location of the cat, they had to work a bit harder for their money on the sierra with the full system (obviously no cat on an '83 car)

no idea about the e39, touch wood the original exhaust appears to still be in excellent condition

Like this? 





The 8-series system is actually two different exhaust systems, one for each bank. It's actually symmetrical looking underneath the car, quite nicely designed! I'd imagine the M5 is much the same, although whether there's space in the floor layout I'm not sure cos obviously lower spec models have a simple one-sided exhaust. All the 8 series have the quad exit system so it was inherent in the design.
