Several of you have asked me to post this graph. The red line is the SLP headers and the Blue is the Kooks 1-3/4". Both headers were tuned to optimized output. This was an older GTP head and cam car.

that's quite a big difference in power...i thought all headers dynoe'd near the same...not ~15hp difference...

I had similar result's doing the same swap. I think it's worth it just to get back the ground clearance

Not much of a difference untill 5500 then the Kooks take off. Thanks for the good comparison

I'll be posting SLP to QTP HVM results soon.

Interesting info. Thanks for posting it up.

Thank's for the graph, I take it that the Kooks was the regular collector and not the merge. Nice increase in #'s by the way.

i didn't think kooks had the merge stuff...i thought that was qtp's stuff

These were straight 3" collectors. Kooks does have a merge option.

Yeah, that motivated my swap also- clearance.

Glad I listened to some of the guys on here and went with Kook's. Thanks for the graph.

Mike, Thanks for posting these results. I'd like remind everyone that Kook's caters to the average street cruiser as well as the all out racer. We have headers for whatever engine size and Hp your LS1's can dish out. Mikey will be more than happy to supply any Kook's products you may need. Nick "Kook's Headers"

Excellent contrast!!!! I love seeing product comparisons and before and after numbers Any plans to add the Kooks spiked collector to the comparison to see what the diffence would be?

I remember Nick telling me that for a stock application the merge collectors would be marginal and no need to spend the extra but would help more on bigger apps.

i've been planning on swaping my slp Lt's for kooks for a while now. Will the heders bolt up to my Slp y-pipe, or will i need a new one also?

mikey...what would the gain be if you added the merge collector option?

I switched from SLP to Kooks and I needed to use the Kooks' Y...the SLP one would need modification to fit...hope this helps.
