Thats what I am shooting for with the exhaust mods.
The headers and shifter have arrived. Still waiting on the Corsa and the motor mounts.

Did you get the catted Corsa setup or the OR version?
A couple of years ago, I worked with AT&T and NCDOT setting up the fiber for the traffic system control (and the newer "Gotcha" cams
) in Wilmington. Your shop is out 17 past the College Street intersection isn't it? Do y'all happen to have a tubing bender (mandrel type)?

Well it was a mod fest last night! We banged out the install, including....
Creative steel motor and trans mounts
B&M short shifter
Kooks 1 7/8 long tubes
After waiting two weeks for the Corsa exhaust, and all we got was empty promises on ship dates. I went ahead and got a set of Kooks conection pipes to the stock cat back.
It is like a new car all over again, the motor mounts are excellent, the shifter is awesome, and well the new found power...................
Here is the comparison from the last dyno session which was K&N intake, Flowmaster mufflers, and a custom tune, to tonight with the latest mods.
The only difference from then to now is the following parts...
Hendrix Engineering clutch kit
Spec Steel flywheel 24 pound
Kooks 1 7/8 long tubes with off road connection pipes to the stock catback.
Retune
Might be able to squeeze out another 5 hp or so with the Corsa when it eventually shows up.
I am very impressed!

These are SAE legit numbers. Hell we made probably 8 back to back runs with only enough time to reflash the PCM in between making small changes. It repeated out every time. Seat of the pants is a night and day difference.

I dont know about 25hp with the LS7 clutch, The LS7 is still a pretty heavy piece. My spec steel flywheel is around 24 pounds, a lot lighter then stock, but I still wanted OEM driveability with it. Which I received. An ultra light aluminum would have freed up more, but I did not want it to be a pain to drive.
I figured my Hendrix clutch kit, and Spec flywheel are good for around 10 -15hp.
I just put on another 1200 miles today, the car is a blast to drive! I still averaged the same 24 mpg I had before too. The B&M shifter does transmit a little bit of noise, but still one of my favorite mods to the car.
