I understand what you guys are saying and I would give them away but I am not about to lose money and from the start I have said that I will accept offers but they have to be worth it. I just figured I would offer to people looking to buy the gmpp manifold a cheaper alternative. I guess if someone wants to come pick one up I would sell it cheaper.

 

$110 shipped if anyone is interested

 

bump need to sell this

I'll have another manifold for ya Saturday bro... and I'll give another opinion for you guys!

I have one of his manifolds!!

Damn people... I will give a testimonial to these here this comming week!

He is a good guy, and I trust his work. I have let several others look at his manifold and say he did a DAMN good job (one comming from one that ports manifolds aswell!)

Give him a break.... You still got my vote bro!

 

how good is thsi will it mount to stock dp...
also is the extruned ported more or is yours

 

I ported mine a few days ago, took before pics but forgot to take after pics....haha sorry guys....I think it made quite abit of a differance....you can see where the restrictions are.....The outlet is really bad too just before the collector..... but yeah....it will make a little bit of a noticable differance.....If anyone is intrested in buying this.... Sorry to the OP, but I am cheap and do my own free mods but some people dont have the tools, so maybe someone will buy it... Good luck with the sale!

 

You did the porting yourself?

 

I did the porting myself and these are cheaper than the gm manifold and they will bolt up to the stock downpipe. I personally think this would flow more than the gm manifold just for the fact that it is smoothed out alot more and opened up more.

 

It's cheaper, but not better.

 

why u say that?

 

interested in how this turns out...

 

I'm interested,I'll buy one from you next week,only one question when porting you did not open up the collector area did you?

 

Its opened up also still bolts to the downpipes on the ss/sc but I am not sure how small the downpipe is on the other motors.

 

I been told that porting these is well worth it,compared to the gmmp,but i was also told if the collestor was touched there would be a loss of torque

 

Interesting, I was wondering why my GMPP's colletor is still a little rough.

 

thats just poor quality

 

You just said when the collector gets touched, you lose torque. That's maybe why they didn't mess with it. GMPP only offers 7% more cfm than the stock SS mani.
