After 1 failed order and a lengthy wait (3 months which was frustrating) finally got the Milltek through and fitted.
I used TSR Performance in Cornwall
Who will ship it anywhere in the UK as part of the price. It comes in two massive boxes so shipping to the fitter is the best option.

At £2,253.00 all in it was the cheapest I could find and their service was great.
Fitting was at GB Autotech in Luton who did a cracking job-apparently fitting Milltek can be a pain but the noise is worth it.
Didn’t realise that the OEM exhaust was mainly one large part so had to hire a van to remove it. No chance it was fitting in the 5.
Anyhow, the exhaust:

So finally we move to the ‘Money Shot’. Firstly a comparison of the sports exhaust. Cold start in auto then into dynamic:

Milltek with semi warm Start in auto and then dynamic:

Car is stock.
As you can hear-quite the difference!! There’s no drone and lots of pops and burbles in dynamic on the overrun.
It’s like having a new car and really loving the new sound. There’s a slight HP gain (10-20 bhp) and it does feel a bit more responsive.
All in all well worth the money and now the car sounds like it should do stock.

People were always asking me to rev my standard RS4 and every time I refused through embarrassment of how quiet it was! Yours does sound much better. Damn those Noise Regs.

Cold start video-car was in a multi story overnight so it was rude not to!

Is there a valve on both sides of the exhaust? If not does it show a fault code? Exhaust does sound nice

There’s one switchable valve in both sides (you can see it in the photos) as opposed to the twin pipes in the old OEM sports exhaust seen here:

Milltek throws up no fault codes at all-that comes if you fit down pipes (particularly catless). No idea how the single valve in the Milltek works but as you can hear it makes a massive difference. Also gain 10-20 bhp which is noticeable and the car feels ‘lighter’ and more responsive.
Well worth the money-shame I had to spend ££ to make it sound like it should stock but it is what it is.
