So, after reading Rob's write up (pippyrips 'v' MRC), I bit the bullet and decided to go for the same, which was intake manifold removed and cleaned, ITG filter, No-cat downpipes and Milltek non-res, non-valve and re-map.

Milltek had a bit of a mix up on the pipe so I had to go the resonated route if I wanted my car completed in one visit.

Result? Well, firstly I'm glad I went the resonated route; I think non-res would be just a bit too much. Res is plenty loud for me thanks!

After driving it back from MRC, all I can say is christ almighty, it's like a different car. It feels so much more alive and powerful and the noise...oh, the noise, what a lovely sound.

MRC fitted new plugs and did an oil/filter change as well (I supplied oil/filter).

The carbon/oil deposits were bad as you'll see in the pics below.

Rob is due to take his car back in to have the intake manifold removed to see how much it has built up since it was cleaned. MRC know what is causing the problem and will hopefully have the solution to it soon'ish

Thanks to Doug and Lucas and the rest of the crew at MRC for making my RS4 awesome with a capital 'F'.

Pleased for you .. the valves don't look too bad ... best get some wynn's to keep them that way .. welcome to the 414 club ... I am not a member yet ....

Interestingly, I'd already added Wynns about 2-3 weeks before the work was done - hmm, look at the difference it made! BTW - car had 20,000mls on the clock.

Karl, you used the spray ? or the liquid in the tank ?

Andy, I used the spray and the liquid.

Nice one fella, I cam very close to going down the MRC route, but im interested to see how long it takes for the valves to gunk up again. Have you got it booked for a power run? woudl be interesting to see what power your putting out,

Karl .. did MRC tale pixs of the vanes ?

Well done Karl, glad you are happy

Andy - I think i actually have one in my boot! They are very sticky and as you would imagine being upwind of the valves.

Sonny, no I haven't got it booked for the dyno. I am really happy with the power it's now kicking out, whatever that may be. The fact I'm happy is enough for me.

Can you tell me what the costs were involved? PM if necessary

PM sent

Could I have a view on cost as well - the queue is forming!

What are you going to do at MOT time with the de-cats?

Me too if you can,it looks like i need to factor this into the purchase of a b7

Maybe MRC should advertise a price for a decoke on RS4's with over 1000 miles on the clock - could send flyers to Audi dealerships!
