Since I take the car to some shows, I wanted to keep my warranty but ditch the stock manifolds. So I added some DT Shorties! Didn't really notice any difference.
I did have some issues with the gaskets matching up to the high flow cats, had to double up the gaskets on each side. So far so good.
At the same time I got some 22" 360 Forged Wheels in and replaced the GM 21's. I was trying to make my car my own and I saw one too many camaros with the GM 21's on it around me.
Also had custom center caps for the wheels:
Caved in and took the car down to ECS for a tune after installing my VMAX TB from Mike Norris! They are wizards down there and my car put down 420/425 RWHP/RWTQ. I'm pretty happy with it for now
