What Headers yield the highest RWHP Increase?

Phantom2004 · 12-01-2005, 08:10 AM

#1) Kooks-Long Tube Headers with High Flow Cats?

#2) Stainless Steel Works-Long Tube Headers with High Flow Cats?

#3) SLP-Long Tube Headers with High Flow Cats?

#4) Dyna-Tech-Long Tube Headers with High Flow Cats?

Which will give me the highest RWHP Increase?

Of these 4 sets that are well known, is there any Dyno tests done comparing them?

Please Help, have about $1,500

burning a hole in my pocket, must spend on headers!!!

I personally hate Kooks and Stainless Works.... I have the SLP's on my car and love them! And I sell them (w/cats, ceramic coated headers) for $999.00 which is cheaper than anyone else.....

Good price! SLP are my 1st choice. I only had one question though...w/ cats, are there bungs for all 4 sensors. I just ask because I remember seeing them listed at one site where it mentions harness extensions and the need for O2 simulators, even for the P/N w/ cats...

Yes it has all 4 provisions for the O2's, however, on the 05's I would recommend a tune if you have any other mods done..... they sometimes throw a lean code (on all headers for 05's....).

Hmm, im gonna ask this just for the sake of it. Do you think a tune is required for long tubes, catback, CAI and a 3200 stall?

On an 05 mind you.

Yes, on the 05's the programming will let the car run too lean (I've seen this on a few of my customers cars), it can't compensate for the increase in airflow. Besides, the car will come alive with just those four mods and a tune!

Yeah, within a few days I'll actually have my cat-back installed [the CAI is already installed], but I was figuring I'd be able to wait until after the LTs are installed before I had it tuned.

hehe, THAT is the idea.

lesseeee,

long tubes ($1000)
catback ($500)
CAI ($250)
3200 stall ($800)

$2550 is my estimate, maybe you can give me a package deal for 2k eh Steve?

Wait, what am I doing, I gotta get the damn thing first!

Catback is more than $500, it's more like $650 and up.....

not at the shop I would be going to. He did dual 3" stainless on the vette with 2 chambers, welded, for $500. Took him 3 hours.
