RS6 C7 performance exhaust

[P60PNB]

Hi,
Newby here. I have a C7 with a standard exhaust and i want to add some noise. Suggestions please?
The car still has 2 years of warranty and Audi are saying that any exhaust except their sports exhaust will invalidate it....
Ive looked at Milltek which price wise - circa £3500 looks OK but I cannot find any reviews on the product. Loads on Acro....... whatever and however its spelled, but I cannot justify £8k for an exhaust...... Any comments on the Audi sports exhaust?
All comments would be appreciated.
Stay safe.

Miltek cat back is around £1,300 depending on where you go.

Audi warranty will be invalid - for the exhaust component, because you've removed it, they will. Not warrant the miltek obviously. The remainder of your warranty is intact.

I've had a miltek for 6 months and had under the bonnet warranty work done in that time.

The only issue you'll face is if your new exhaust breaks another component, they won't warrant that.
