hollyflowtech also makes a shorty header i ordered mine through summit pn-big-11102flt,they also offer an x over pipe just for the third gen,not saying this is the best performance way to go,but definitly better than those gm logs.

 

Theres no difference over stock with 1 1/2 primarys, 2 inch Y pipe, thats why they are so cheap.

 

Hooker 2460's. They sell a damn good y-pipe for it too, but I can't remember it and its a little pricey.
Or Dyno Don's over on Thirdgen.org...

 

Just got a pair of Hedman shorties and Y-pipe for around $250 from summit--they suffice and do a decent job...OK with them now.

 

yea, heddman 1 5/8 are the best bang for your buck headers.

 

Hey, my buddy is selling his headers and Y pipe, top notch guy.

I have the 1-5/8 hedmanns w/ the y-pipe and love them. Buy some good gaskets though. The paper ones suck. I also have the stage 8 locking bolts, and they work, kinda. You have to retighten them, after the install and a warm up. If not youll be replacing the gaskets soon.
I have the dead soft aluminum flange gaskets, and they seem to work. Ill replace the head to header gasket when I swap the engine.

 

I make these with a lot of improvements over the SLP design.

 

This is the single cat Y:
2 1/2" to 3"
Can be done in 2 1/2" to 3 1/2"
