Akrapovic Vs Milltek exhaust...

[wrekka]

Came across this clip on YouTube comparing the Akrapovic and the Milltek exhaust systems.
Go to 2min 30 for the best comparision.

Opinions please...

Milltek for me.

Can't see how anyone can justify the price of the Arkrapovic unless you want fancy tailpipes only?

Akrapovič for me, it sounds lovely and refined with a better tone. Not in your face like the loud Miltek.

I have been running the milltek system for 6 months now and love it. Yes it can be ridiculously loud but when the valves are closed it is absolutely fine. Some say it is a bit "raspy" at times, but I like its character. The build quality is not up there with the Akra system but then it is around 5 times cheaper. I think for the price the milltek comes in at it is an essential upgrade for the rs6. If people prefer the Akra and are happy to spend 6.5k on an exhaust then fair enough - horses for courses. I would in the future be tempted at some custom systems to see what they can do.

6.5k.....that's a nice holiday or work on house for me.

Each to their own mind.....

Bet cheapest option would be cutting middle pipes out and replacing?....or full custom job?


I've always gone custom and never been disappointed.

Haha makes me laugh..if you spend 80k plus on a car im sure a 6k exhaust wont be a issue!! Aka all the way for me

[D8vil]

Just got akrapovic and its twice the exhaust of a milltek. On tick over it sounds reasonable. Milltek sounds tinny on tick over. I agree it's a ridiculous amount of money but if you own a C7 RS6 money is not your priority

You're paying £6k for the name and the exhaust note. The Akra system offers little to no performance benefit. It's the same 2.5 inch bore as the standard exhaust system and it only comes in a cat back section that mates up to the 2.5 inch OEM downpipes.

Milltek is a performance exhaust, it's a 2.75 inch all the way through and you can opt for either the 2.75" downpipes or the larger 3" downpipes (catted or decatted)

You will gain 50hp from the Millltek exhaust for around £2-2.5k
You will gain 5hp from the Akra exhaust for around £6-6.5k

The Akra exhaust tips look ridiculous, not a fan of the twin pipe into the oval design, looks sh*t.

Sounds nice though and admittedly it beats the Milltek but the Milltek sounds great too up close and personal. The videos on YT really don't do it any justice.

Price - Milltek
Quality - Akra
Sound - Akra
Design/Functionality - Milltek (Lots of different choices available)
Performance - Milltek

For me, price and performance were primary, sound and quality secondary. I just couldn't imagine paying £6k for an exhaust note change.

Paying for just its name and exhaust note?

The Akraprovic is made from Titanium, not some poor quality stainless steel that rusts away after a few years. That's what you're really paying for, there's probably 3k in just raw materials for the Akraprovic system. It also saves over 8 kg in weight and weight is performances' biggest nemesis.

Have Milltek ever stuck their neck out and given an official power gain figure? The development car with MRC ran filters and an MRC remap from what I remember. I'd be very surprised that a Milltek CAT back Resonated system would see a gain of 50 BHP alone. Happy to be proven wrong though.

[geordie jay]

Totally agree with sam!! I will run naked up the m1 if you gain 50bhp from the zorst!!! Would love to know where you got your figures from leo..

[RS6chris!]

Haha makes me laugh..if you spend 80k plus on a car im sure a 6k exhaust wont be a issue!! Aka all the way for me

How many people pay 80k up front??? Don't care how much car is...the cost is a piss take for me...titanium or not?
And as said the outlets look <beep> to me.


But if you want to spend 6.5k on an exhaust crack on....I'm ooouttttt.


I believe ( I could be wrong) MRC claimed very good gains with the Milltek as said above?...50 bhp plus....with thier air filters though.

Didn't know stainless steel rusted away?

From the video I prefer the sound of the milltek.
And the quality of the milltek is good enough to outlast my ownership.

[Leo-RS]

Figures are from MRC,

Stage 1 680-700
Stage 2 740-750

The only difference between Stage 1 and Stage 2 is the full exhaust system. My car has had both Stage 1 and Stage 2 tunes from MRC.

If you follow MRC's Facebook page, you'll find about a dozen examples of C7 Stage 1 vs Stage 2 results.

The C7 exhaust has 4 cats in the system and is very restrictive. The gains from stage 2 come from the downpipes, not the catback section. This is where the Akra system is let down, there's no downpipes upgrade. (I dread to think of the cost if they did offer the full system)

As for the Milltek, yes, although it's not a titanium system, it doesn't need to be. For me, I'll have the car maximum of 3yrs, the stainless steel Milltek will far outlive my ownership. It's very well made and I've not heard of any quality issues personally.

Dont get me wrong, the Akra is 2nd to none build and quality wise, it's just the Milltek offers the performance benefits. )

For those of you with the Akra exhaust, regal autosport in Southampton sell the Milltek 2.75 inch decatted downpipes that they modify to mate to the 2.5" Akra/standard catback section. This will give you the Stage 2 gains although probably not as high as the 750 due to the smaller 2.5 inch catback section. Perhaps around 730 though.

Some of you may have no interest in Stage 1 and 2 tuning though.

Although it's advertised as 3" downpipes, it's an error on the website, they are the 2.75" downpipes. These will also fit to the standard catback section so this is the cheapest way to go from stage 1 to stage 2 negating the need to buy any aftermarket catback section.
