M4 has Cat-back Akra exhaust and JB4 tune, the 997 is tuned as well(sorry don't know the exact tune). 40 and 60 rolls



Obviously with some more mods the M4 would not hang with the Porsche.

Thanks for watching.

OK. This should be fun.

Stock vs. Stock would be interesting. New M3 is quite fast & reputation of under-reported performance #s.

Love the M4 and M3, they are quick for sure. I do love to drag them - all day long though. :evil grin:

Would like to know what tune that turbo had, second race the M4 breaks traction and still pulls away. I have the feeling the 911 guy didn't give it the full beans. A stock 997.2 PDK turbo would murder the M4.

Not sure what tune the Porsche owner is running but yea a 997.2 PDK traps 128mph, vs 118 mph for a stock M4 I doubt the M4 would win with just a tune
