I wanted to post up a review for awhile but I wanted to include acceleration testing with it, and the summer heat made comparisons to my baseline testing impossible. Since today was 75 this morning vs 68 when i did my original testing i decided it was close enough. DA was just under 1000 so both runs before and after are between 0-1000 DA . I did 1 warm up 1/4 mile run then two full 1/2 mile runs and the car got faster every time . 10.53@ 130.1 v box trap , then 10.52 @ 130.2mph vbox trap , then 10.50 @ 131mph box trap(132mph terminal velocity ). The two half miles done on the same flat slope both ways were 16.7@ 156.5mph v box trap 155 terminal velocity ( I lifted too early) , and 16.6 @ 158.2 mph box trap (159 terminal velocity). Best 100-150 mph was 8.02 sec, and 0-150mph no rollout was 14.39 sec. All runs were on pump 93 octane , tire pressure 32 front 35 rear on the stock zeros with 3000 miles on them. Still able to get a 1.57 60 ft. Not surprisingly just changing the exhaust has very little effect on max performance (Best time and trap are identical)however it did seem to help with consistency and preventing any decrease in performance on a warmer day and the 1/2 mile run was the quickest and fastest she's done.
The exhaust is the Kline Inconel louder version (but not the new single tip) . It sounds fantastic , the car is the way it should have come from the factory. Slightly loud than stock at idle but way louder when t WOT with much more character in the exhaust on throttle overrun. The programed pops in sport mode are definitely louder but are much more tolerable to me than some other exhausts I've heard for this car. They are not just loud bangs but have some more complex character. She finally sounds like a Porsche 6 so am super happy with the results. Thats again to Sam for all his help and a very pleasant purchasing experience! Now just need a tune !
Here are the box verify files.

 

Nice GMD! TTS .2s in in base form are proving to be an amazing category killer!

Strong 10.2 on an un-prepped street surface. New heights compared to the .1s at the track in comparable stock form. Def looks to be a 9 sec recipe with a lot less compared to the .1s. Can you post the the vbox 10.2 run? TIA

 

Oops typo 10.52 ! Not 10.2 !

 

Hey G!
Awesome and still insanely fast! Really glad you are enjoying the system. Soon enough we will be pumping it up even more!

 

Ha nonetheless good strong consistent runs for the street. Keep at it, consult with Sam..... with a few very minor tweeks, its there for the asking.

 

Heck yes , considering I'm stock except for the Kline exhaust I'm very pleased , especially the 1/2 mile trap .

 

Wow. 159 with just annexhaust! That is hugely faster than the 991.1s.
