S6 EXHAUST THREAD

A6 All/ S6 All
#21

Yes im in the same boat, the Milltek came with mine from previous owner, with both resonated and non-resonated section so i cant complain, its definetly an improvement over stock. I doubt it adds much power. It seems like its not so easy to get more power from these without dropping the engine and going with those fancy unicorn headers a few people have!

I wonder if i was to get a 2.75-3.0" CBE made locally how much that would improve power, i doubt much, it might be an expensive lesson in how not to spend money on these cars :slight_smile:

Its such a shame for this car, such potential but so few sold and so little aftermarket support. im defintely in the wrong country to go fucking with a car like this to try squeeze a few extra ponies from it!

Im still going to keep it for another while yet!

A proper exhaust makes a huge difference- it’s not an experiment it has been proven out. The stock exhaust end to end completely chokes the 5.2 along with the stock tune.

Especially the s6 from an exhaust design standpoint

Do you mean a proper cat back system or a full header back system?

They definitely handicapped the s6 on purpose so the rs6 released a year later would definitely shine.

Its probably cheaper to sell the s6 and buy a stock rs6 rather than a full header back exhuast for the s6, well at current market values i would think.

This is only my opinion as a noob to Audi world.

Proper everything exhaust related. But yes start with a proper CBE with smooth bends 2.75ish piping with minimal or no neck downs proper placement of the xpipe and you will feel like it’s a different car.

Any other clips out there?

Hi - just picked up a new (to me) 08 S6 and I know that i will be doing some exhaust work to it for both power and sound. I see that Fabspeed makes an x-Pipe unit that is advertised for the V10 S8 - does anyone know if this also fits the S6?

Thx

It will not, but I designed my system similar to that setup. JHM has something in the works, check out v8a6 project thread and you can find more info about what that exhaust might look like-
