How much do these really benefit especially if you have an x pipe? Are they worth the extra money?

Are you talking about header collectors? With an x pipe and headers youve already got an excellent setup

Yes. Ive seen a graph where headers with the merge collector/merge spike gained 8hp/12tq and 30tq in the midrange, but like i said that was through a y pipe

I thought merge's was in y pipes and that if you have a quality merge that you could benefit significantly from it

What headers you got or are you getting?

He's referring to this...I think.





OP - I'm a fan of the "every little bit helps" club. Assuming you are referring to the spike, pretty sure you're not going to be able to opt out of the spike as long as you stick with a hi-end header brand - Kooks, ARH, QTP, etc. So to do a comparison in price only focusing on the spike is difficult (can't be done) as their are other cost drivers that make "good header A" more valuable than "average header B". In otherwords, if you're gonna pony up for "good" headers, they will come with.

A true race "merge" like you talking about with a 2 1/4 or 2 3/8 converge section would work good.

Yes LPE 403 that is exactly what I am talking about. I am asking this because the cheapest brand I can get with that merge spike collector design is some used 1 3/4 Kooks for 600. Or for 360 I can get stepped Edelbrocks with a 3.5 inch collector. I already have a set of TDs so my question is would the extra 240 be worth the gains.

This style of your going thru the trouble to do it. If not, don't waste your money.

Right, I just need to know that since im running TDs its not going to only give me 5 or 7 hp over running a standard collector. Mine is a street car and will be for 99% of the time. Im almost considering ditching the TDs and finding a GMMG and getting BBK longtubes with their ORY

For the extra $240? Not worth it, IMO. Put that towards an LS6 intake instead

The spike cuts down on turbulence and doesnt have anything to do with being a merge collector or not. Merge collectors are simply a necked down section in the collector. With a Y-pipe or any sort of restriction downstream the benefit of this design is dulled. To the OP, I wouldnt bother paying extra for these to run a Y-pipe. Keep to the standard collectors

This is the basis of the design. It doesnt work if there is much back pressure
