LT Pacesetter Headers =Gains? Getting ready to put off road LT Pace setter headers with Y-pipe on my 02 Z-28. What kind of gains do you think I will see in the 1/4 if any?

I went 12.7 @ 109 with pacesetters and SLP lid...automatic with stock 2.73 gears...no tuning.
After adding 3.73 gears it went to 12.6 @ 111....but I also lowered the car and added heavy replica ZR1 wheels with 17x11" ones in the back.

I threw o2 codes like a son of a bitch and slowed to a 13.6.
I replaced the splice o2 with a Corvette rear and it's running much better. If I were you, I'd invest in extensions.

I didn't get dyno'd before or after my headers, but I will tell you that my car felt like a whole new animal after the headers. I swear to god it felt like a 14 second car with the stock manifolds 
. After headers it was going 12.9s at 110-111, full weight. They're an awesome mod for not a lot of money, that's for sure.
