Of course Chrisk I now this is not something new , but its nice to have more data about this little mod.
Cant wait to see what a cat-back can do , I think it will be very similar to piggie pipes and the tune its going to wake up this 2 mods , I really hope to see 3 tenths and 2-3 mph more when the cat-back and tune are finished.
Regards.
This is what I was saying…it wasn’t a dig at you…
I know Chris dont worry . 
Thanks.
Guys A friend of mine just bought a 2007 s6 very low miles 21.000- we change the air filters(k&n) spark plugs , fuel filter , oil , and coolant ,and got a good race… All I can say its was EVEN up to 200km (124 mph) here its where the S6 start to pull VERY slowly , we got to 250km (155mph) and he was 2-1/2 cars ahead we tried 2 times same result.
From 0 up to 100km (62mph) I got half car in front then in 3er even up to 5gear(almost 200km).I thought the S6 was going to pull on the s4 , but it did not, we are going to try next week again …
That sounds about right to be honest. I wish the s6 was faster.
having the 2 extra cylinders will help it breath up top so that makes sense. You would htink he would have been a little bettwer down low. carbon maybe…If he just got it I would bet the previous owner didn’t do the carbon clean. That might change things… Still I don’t thnk folks know just how good the B6 S4s are.
New info on the S6 (v10) we did the intake carbon cleaning ( not that bad) and take out all the cats ( 4) (stock exhaust ) wow the diff we ran last night and he got 8+ cars easy to the same speed , now the car traps 109-110 mph from 104-5 what and improvement ! will post more info this weekend.
Time for the s4 now … ;D
Regards.
About 50 hp from decat/decoke
Yep … with a good cat-back and tune the s6 can go fast… easy 112+ ( in the p-box)not bad for such a simple mods , the only real prob its to take out the motor , not difficult just time consuming.

Finally had some time to test the “new” catback .
Mods
Piggies + 2,5 catback.
93 v power
temp “28” degrees Celsius ( day )same track etc about 22 degrees more! than the best last time.
NO weight reductions and over 40 lbs of stuff inside de car( spare wheel in the car etc) almost half tank of fuel etc 165 lbs more aprox .

This weekend take all the stuff out , minimal fuel and see what its does , then the main cats out test again and FINALLY the JHM Tune.
10-2 degrees are about 1 tenth off and 1mile fast trap speed did measure the hp with the p-box and got 270whp
with the same 6 degrees or so from my last best time with this mods this car can do 13,6 aprox at 103 mph+ good improvement over the oem exhaust .
keep you updated .

The catback does work good, the 2,5 pipe does help the low end torque and a little the top end , 1question how much do you think the main cats are going to ad? Im asking this because im thinking on keep them in place.
thanks.
not much
Leave them as is
I trapped 107.1 with precats gutted + main cats in tact and 107.6 without cats at all.
