OEM Exhaust with AMS DP's Dyno
Same shop, same dyno. I know, dynos don't tell us much, but I wanted a comparison between oem and catless downpipes. I went to the same shop and the car suprises me once again.
Stock dyno a month ago 552hp One mod, catless dp's, today's dyno 580hp When car was bone stock I ran another M5 with Akra exhaust, AFE catless dp's and some piggy back tune and we were dead even 3rd and 4th gear. Niko, if you are around I would like to compare our cars doind a 3rd gear pull.

Nice runs... although your baseline was in 100 degree weather and your subsequent ones were in cooler temps.
Im still on the fence for catless or catted pipes; hearing about the waste gate noises, cel issues, and sometimes marginal gains. I wonder what you would have pulled baseline at 80 F.

Nah, we just got them and stayed LOL Its funny I drove my C4S yesterday and it was just fantastic to drive for so many reasons: carving tight turns, high speed bends and screaming hi rev exhaust notes and yet today I was equally happy with the M6 blowing down the Mexican toll roads at 150 +++... of course when I was going into a turn at 130 I didnt feel all too courageous like I do in the 991

The onramp at bristol to the 405 S is a great test of steering- chassis lean- suspension- and power with control. I love it in all my cars but especially in the R8...

Yes, but it would require too much work. O2 simulator located passed the resonators, which would serve as a secondary o2, but wiring would be a mess. Might as well just wait for ESS tune, otherwise nothing else works. Guys at EAS could nit figure out why the car makes more power than others and I swear I didn't do anything special, but I won't be convinced until we get on the road and do couple 3rd gear pulls.

On the top end catted will be 10hp less than the catless. They use race cats, same ones they use on the 1000+ horsepower GTR.
