I’ve searched around for different collectors that would meet what I was looking for to work with my upcoming changes to my exhaust setup. I found a guy on ebay that cut me a reasonable deal on a set of 3-1 merge collectors that had a venturi extension to try and keep velocity up.
1.5” primaries (wish they were 1.75s) to a 2.5” merge and then back up to 3” to meet up with my new true duals. Needless to say, this guy totally delivered. It was a bit spendy compared to others, but when I saw the fab quality, I decided it would be worth the shot.
Mike Davis of Davis Headers in Cali (eparts505 on e-bay) is the one who did these up:
For those not familiar with what I’m doing, this is a lightly overbored 3800 Series II V6 in a 2000 Firebird. Big cam, higher compression, big valve race ported heads and a lot of other fun bits that will be bound to make this car a screamer on the auto-x and road course.

those are awesome especially the merge of the pipes on the inside.

It might be the flash screwing with my eyes, but is that daylight I’m seeing where the primaries come together?

Just the flash.

That is some damn fine craftsmanship!

Niiice :) it’s pictures like this that make me sure that I want to make my own exhaust manifold rather than paying ~£500 for a cheap 6-3-1 (or £1500 for an expensive one).
Might take me a while, but I’m certain I can do sweet things like properly merged collectors and the like...

Doe’s he do bigger stuff, like a full set of headers? I want a set of stepped headers for the M, but Supersprint and CPI are dumb expensive.

Looks like it. It was $425 shipped with O2 bungs for my collectors though, so I don’t know your price range. Mike Davis 949.244.0852 this stuff was from Corona, CA area.
