IDk about times, but I gained 20-25 HP and TQ Peak and across the curve with the Kooks and off road H. I gained almost 40 TQ at 3500RPM...talk about get-going quicker.

yes, and that was with 1-7/8 on a NA motor..should have been 1-3/4. Got the larger ones in prep for the VMP TVS in Jan/Feb.

It was at napierville dragway near montreal.....it was a very cold day. It was like 38 f ,last fall.....
1 3/4 also make very good power unless youre looking to reach 1000rwhp.
Since your in Montreal too i could sell you my ARH lt's for a good price
it's a great setup and a great sound, we have some great deals going on the kooks right now as well.
I am not sure, as our car was never on the dyno when it was stock....or after the Kooks.
We went 13.01@110 stock, with our 2011 Gt Auto.
Added:
Kooks Headers / Mid Pipe / Stock Catback
JLT CF Intake
VMP Tune
3.73 Gear
Circle D 3200
Car went 11.72@117 with those additions, first pass, compared to the 13.0@110 stock. (This was in about 2600ft DA - both passes)
