Milltek power increase

[TWH]

Does anyone know roughly what power increase a milltek dual pipe cat back system gies a stock RS4? Or does it just let the engine breathe/rev more freely?

My car was putting out 402 with cat back and nothing else done.......... they usually claim about 10% and obviously this is not the case............ 22 bhp gain, which could have come from fuel alone......... but the car certainly pulled better after fitting and sounds soooooooooooo much better, now have cats too and even more sound and more go, remap done at the same time so I cant tell you what the gains were individually. Certainly pulls bloody well, and feels so much stronger than pre-mod!

I've just had Milltek Cat back on mine and even with the resonated section the biggest difference you will notice is the noise that it makes. I know some have found this to be too much but it is definitely sportier so I guess it depends on your point of view. Haven't really had chance to test the performance benefits yet but Castle Combe this weekend should be fun.

With the Milltek on the S3 I could tell straightaway it was more powerful, not so noticeable on the RS4 but then I already have approx. 420hp so another 20 isn't going to be massively different anyway. Does look good as well

Sweet! I was going to be down at castle combe this weekend but am hopefully gonna get the milltek on instead!!

I love the Miltec. Hope you do too.
It gets better and better with time.
