Reduced Temps

Nice work Sam in the simplicity of the mod and results. Truly a no brainier for anyone looking to improve on their purchase. Im so happy to have done this on my new .2!

Nick Yoskin

Nice work. Looks like Atco to me, fast track without a doubt.
I am assuming just exhaust work? Tuning is not available?

NVRANUF

PLUS.. He ran those times on winter tires no less!!

Can you share the tire pressures used Front and Rear ?
Looks like you got it nailed down ! Congrats !

The run was a my Atco but no this was on the stock P zeros. He put them back on after going to Atco the time before with winter tires
It is a truly breathtaking run to go 10.2 with an exhaust

NVRANUF

True, my bad!

• stock w/snows 10.69
• stock w/exhaust & P zeros 10.29

Would it be fair to say the OP's improvement isn't 100% due to the exhaust alone ?

Curious what stock w/P zeros alone would have netted the same day.

Impressive non the less!!

I am just as positive that the tires helped as I am that the exhaust did. I don't think any fully stock cars have run less than 10.5xx. The system is high flow, dissipates heat so the car runs optimal and its also very light. We also have seen a 2-3 mph increase in the 1/2 mile on the same day between a stock and a By Design/Kline car. Mike did 163.7 which is faster than some stage 2 991.1's. Truly amazing cars, a great track and some great launches too!

Of course the summer tires had an improvement. But a 10.2 for a basically stock untuned car is outrageously fast. Shows how much of an improvement the .2 cars are

NVRANUF

Interesting conjecture, whether a fully stock .2 will run under 10.5xx. and by how much.

SamboTT@ByDesign

We have yet to see. Good times ahead!

Thanks guys - I love my 991.2 TTS and the Kline headers/exhaust were a perfect match both in build quality and performance. My butt dyno tells me the car is stronger and more responsive and my ears love the new noise. Sam and Kline hit it out of the park and their service match the excellence of the product.

NVRANUF

I'm seriously rethinking exhaust "needs" for my incoming .2 TTS after seeing and hearing your car!
