Good custom exhaust fabricator

[OccamsChainsaw]

Evening All
I have a 2002 M5 with a Milltek exhaust + high flow cats. It’s a lovely exhaust, but my god it’s loud! Unfortunately Milltek don’t make it any longer, so can’t provide a resonated version to quieten it down ... they’ve advised me to get a centre section with resonators custom made.
Can anyone recommend a suitable company to do this? There seem to be plenty around that say they can, but I’m concerned about putting black holes in that beautiful linear power delivery. I don’t mind losing a couple of bhp at the top, but affecting drivability is a no-no, so it’ll need to be an outfit that understands gas flow etc, and preferably has a dyno, rather than a “you want loud, yeah?” type.
Any ideas? I’m near Southampton, but will travel for a good job.
Thanks chaps!

Buy a couple of silencers and have a local exhaust fitter cut a section out of the Milltek and fit the new ones in.

Cheers fella. Why silencers instead of resonators? Don’t resonators give a cleaner gas flow, with less resistance?

Hayward and Scott maybe they've done plenty of E39 M5s

Contact Russ Fellows, here: http://www.russfellowsfabrications.co.uk/index.htm...

He did a lot of early work for Evolve on headers for the E39 M5 so will know a lot about gas flow. (He produces his own version now.)

I very nearly bought a bespoke back box system off him. He'll tune the exhaust to a loudness level that releases a bit more V8ness than the stock boxes, or whatever you want. Several other E39 M5 owners have been very pleased with the overall quality of his work.

Thanks gents, most helpful. I’ve just dropped Russ a line and will be looking at H&S tomorrow.
