Hello all. I've been lurking for a little while as I waited for my RS4 cab to be delivered. Picked it up a couple of weeks back, v impressed so far - a lot better than the S4 I part ex'd.
I'm thinking of getting a Milltek exhaust fitted (valved and resonated), and wonder if anyone can help with a few questions:
- The standard exhaust is pretty unobtrusive at cruising speeds, which I like. is the same true of the milltek systems? my other half is unlikely to allow anything too lairy
-is there any effect on the audi warranty from having one fitted
-is it something that one should disclose to an insurance company as a modification.
-Tuningwerkes in Corydon is just down the road from me, so would be the most likely place for getting it done; does any one have any experience of them?
Thanks in advance.
Some Milltek questions
Some good questions
I am looking to do similar but with cat-bak, non-resinated and no valves. Also saw down pipes 100 and 200 cell, am looking into these. Got a good price quote from Checkpoint in Aberdeen, any one had dealings with them.
Would the down pipes make that much difference ? and where in Scotland is a good place to get a re-map done as well.
All thoghts welcome.

I would do a bit of research as I have heard that certain types of miltek exhausts cause a slight loss of torque. Not 100% but someone should come along. I would definatley inform the insurance company and go into having it fitted with the view that if your engine goes pop the dealer may attempt to apportion blame. The only way i would fit one would be if I knew 100% that the exhaust flow was exactly the same as oem. but im not bothered about performance increase I would just like a bit more noise. Have you tried disconnecting your flaps? 
I am over cautious.
I am over cautious.
Full system Milltek's can cause a drop in back pressure because they are freer flowing and can affect MAF sensor readings, which is why most who have a full system also get a remap to compensate for this and also take advantage of the free flowing system to get maximum gains from the exhaust which an OEM map will not.
Catback systems will not cause such issues.
Moog, my understanding is that the resonated valved Milltek will provide a sound similar to the OEM 'Sport' mode when you haven't pressed the sport button (if you see what I mean) and when it is pressed and far more aural burble. Non resonated will make it considerable louder. All this having looked into a Milltek myself.
Skip, I've never dealt with checkpoint but if you are looking at down pipes and cats that is where the power gains are. However, a word of caution, 100 cell cats sail close to the wind in terms of emissions regulations, you may be safer getting the 200 cell cats. It does have a slight effect on noise in not being as much, however fr the sake of your warranty....
With all these you should disclose to yuour insurance company, most will not raise the premium, especially on cat back as it is not for performance advantage. If full system it may be viewed differently.
As to remap Skip, Star Performance in Kirkaldy has good reviews, however I do know from other forums that Jim isn't into remapping OEM RS4's as the gains don't justify the time and cost, you would have to go the full system Milltek route before he may consider remapping your car.
Personally like said previously I'm doing neither, looking at an X-pipe replacement for the resonators finances permitting to get a better exhaust note but maintain the rest of the OEM exhaust.
Warranty wise, only the exhaust will be void of warranty, it should not affect the warranty for the car and other mechanical / electrical components.

Hi Moog
I've just been through all this so hopefully I can help.
I have a B7 Saloon and had the valved, non-resonated system fitted at APS in Brackley last week.
1. Cruising speeds should not be a problem. Both systems boom at lower revs (around 1800/1900 rpm) but having the exhaust valves certainly helps to keep this to a minimum, and as I understand it this is much less of a problem on a cab.
2. As P_G points out a cat-back system should only affect the warranty on the exhaust, which I did not consider to be a problem. I took the view that having the cats and downpipes might make Audi look at the engine warranty should anything go pop so personally felt that this was not worth it.
3. Absolutely you should tell your insurers - I'm insured with Elephant and they put my premium up by about £40 - although this is for the remaining 7 months or so of this insurance policy year - so probably £60 ish over a year.
4. I have no experience of the company you mention, but can highly recommend APS in Brackley - speak to Ed or Nathan.
Can I also recommend a chat with Phil Millington at Milltek if you are still not sure. He is the big cheese there and used to run an RS4 with a Milltek on himself - he seems happy to talk people through the pro's and cons, and they can always fit it for you too if you don't mind going up to Derby.
Overall I was also very nervous as not only had I not modified a car before, and knew the non-res would be loud (I actually had an agreement to swap for the resonated centre sections if I wasn't happy), but I LOVE IT! Nice and quiet on the motorway but completely mad when pushing on!
Hope this Helps

Interesting point you make on the boom or resonance drone Olif-H, it is the one thing I want to avoid which is why I am considering an x-pipe only.
Had resonance drone on my S4 and it does get to be a bit of a pain becauise you can't cruise in 6th on the motorway at around 2000rpm or it would do my head in, thus either 5th or speeds you are not allowed to mention in 6th to keep out of the resonance band.

Have you considered the Tubi? http://www.scuderiasystems.com/M-Media.htm
P_G - yep was really concerned about this. However you don't need to be at illegal speeds in the B7 RS4 - I think mine is in the resonance 'zone' at about 50 mph in 6th - and to be honest if I'm doing 50 then I'm usually in 3rd, 4th or 5th, depending on the driving situation. At 70mph it's as quiet as a mouse (well not quite!)...
The only boominess is in traffic when it's a bit start/ stop - but I seem to have got used to it already! A friend of mine who's also a member on here has the resonated cat-back and he certainly didn't seem to think mine was too offensive
Also the guys at APS said they were surprised how quiet it is

It is not made by Milltek. It is made by another fabricator and is along the same lines as the ECS H-Pipe that someone linked into another post previously.
It is the section between your cats and your back boxes and essentially instead of two separate pipes the two meet together in an 'X' formation with them being welded together and opened to meet each other at the apex. Coupled to the increased diameter of the pipes it improves exhaust flow and note and maintains all of the OEM system bar the resonator section.

I presume this means cutting your OEM exhaust though?
As for the Tubi - I spoke to Scuderia who are apparently the sole UK outlet and the guy said they just recommend fitting non-valved (you can now get valved according to him) rear sections - which again would mean chopping the OEM exhaust...
I just decided that Milltek are very successful with the B7 because their product is probably the best. Yes, it is expensive, but on a £50k+ car I would rather pay a bit more for the right solution

The X-pipe fitment requires one cut point on each pipe as the section next to the cats is clamped IIRC.
I agree Milltek have a good reputation and market on this basis, however they are not the only solution and for me Milltek have got to a point where the cost is prohibitive given the results and what else is available out there.
As for valved vs non valved, I only got sanctioned to get the RS4 because of the valved system and having the option when the family is in the car, if I go and get a non valved Tubi I may well be living by myself again!
