VIDEO: Kooks / Corsa (LS3 version) on my L99

[Darth_Emma]

I also have Kooks LT catted 1 7/8" headers on my L99. I put a Borla touring exhaust on it and I have a CAI intake and a tune. I got 362 RWHP on the dyno. I think the L99's usually start somewhere between 315 and 325 stock. They didn't dyno the car when it was stock, but I do know the car definitely has a lot more power than it did at stock and I LOVE the sound with the headers and exhaust.

I thought I was sold on the ARH but those Kooks sound nice

It's definitely a winning combo. Also managed to put down 366 RWHP and 380 TQ on a mustang dyno yesterday. Not bad!

Check this out:

I'm trying to follow in your footsteps. My LS3 Corsa catback just arrived, but I'm reading that the L99 version includes spacers. What did you use or are they even required?

I called Corsa before I ordered mine. Unless something has changed in the past year, there is no difference in the fitment between the LS3 version and the L99 version.

Dunno. You have not said if you're running the sport or touring version of the Corsa.
