Open Headers = New Personal Best
 

I've always wanted to try open headers at the track but driving it there dropping the cat back and y pipe at the track then putting it back to drive home was not worth it. So, I dropped the cat back at home loaded it on the trailer and hit the track. First run with y-pipe 10.87 DA was only 90 best one I've ever seen. I thought that sucks what a waist of time. So I made another run this time 10.85, still disappointed. Now I took the y-pipe off and ran a 10.84 a new best but still come on. Decided to hit it one more time and boom 10.78 @ 124 DA was 500ish. Now that's better. Since the car's getting faster all day I said one more time, 10.81 @124 DA climbed to 1200ish by this time. Best with full exhaust was 10.85 @123 vs. open headers 10.78 @124.

Nice runs, Congrats on the new best

Nice! Congrats on the best! Just be careful the o2's don't read the fresh air amd mess up your af and cause havoc. I dunno lt but the ls has the o2 towards the end and can happen

My O2's are right at the opening of the header collector but I run open loop when racing so no worries.

Nice no problems for you!

Thinking about trying some collector extensions and seeing if it gains anything over open headers. I just can't decide on how long to start with.

What do you run for an exhaust when it's on the car?

Hooker LT's with Hooker y-pipe, single 3 inch extension into a Borla 40474XS muffler with 2 1/2 dual out.

Congrats on the new best.

Congratulations!!!

You have some real fast times. Nice!
