Alright so all the pieces are ready to be put in their place. This weekend this bitch will be going on! I cant wait! Here are some pics as a teaser. I will upload install pics as we progress

I will be getting another tune/dyno once the header is installed and cant wait to see the numbers!

I have not had any problems with my GMPP manifold at all. But this JBP piece just makes it look like trash!

Enjoy!














So the install wasn't that hard, just time consuming. We did everything in my garage on jack stands with hand tools! (that ones for you Joel. hehehe).

Like it was posted in the Group Buy thread, you have to take off the rear transmission mount and unbolt the steering rack to give you enough clearance to fit the header up from underneath. Once we did that, it was fine. Some of the bolts are hard to get to, but oh well. Deal with it. You may also have to move the AC pipe an inch or two away from the primary, and I pulled a little bit of the firewall insulation back just in case. Fist try, and no exhaust leaks! Woot!

It feels like the car has more low end, and seems to deliver the power smoothly throughout the rpm range. Hopefully we'll get to dyno this sucka soon!

After the install













And some vids! Also, I have the stock downpipe on, so it is not quite as raspy/gurgle-ish as the videos on youtube. But still sounds nice!

 

Nice! U gonna sell the gmpp header?

 

My buddy has this on his car, it is amazing, sounds just incredible. Just wait till you turn it on for the first time. haha.

 

Yes sir

 

how much??

 

goddamnt!!! i cannot wait to get mine installed. post and tips for easy install, thanks

there was a group buy for like 329 i believe. i would just pm jbp and see what they can do for you if your interested

 

i already have the jbp header..i wanna buy his gmpp header..

 

^^ you didnt like it?

 

na man i dont...the flow of them is fucked up..im telling u..and i only gained 4 whp from these headers..

 

im going to check mine out and see how i like it...if not probably will got CIA or ZZP

 

I'd like to get $100 for the GMPP...but I dont know how much shipping is gonna be...

 

good deal..man it should be like $10 to ship through sups..let me know

 

I'll let you know asap.

 

And she's on! Install was pretty intense. But thanks to a new friend, Joel, we got it done! I'll post up more pics tomorrow and a few lessons learned. And maybe some video?! hehehe

 

Sweet

 

Nice man! can't wait to see pics!

 

the JBP headers / any long tube headers aren't made for top end/ peak numbers

it's all about area under the curve

 

I actually lost 3 peak HP with this header.

 

Thats gotta be the weridest header i have ever seen.Cant wait to see your results.

 

everyone is talking about how they lost peak hp. Can anyone post up the before and after dyno's to show the gain throughout the powerband?

BTW, no one cares about peak numbers except dyno queens.

 

apparently me and you are the only ones that think that.. NOT to mention.. i doubt the dynos were done on the same day usually.. there are very easy ways to gain/ lose 3 hp

 

I'm interested in going fast. Not dyno sheets. I just don't know if i wanna spend the dough on that header. It's really expensive.

 

ditto man i want to see it on 2.4 since i plan on getting this & a 3" dp and 3" catback itll give a BA sound to my boosted 2.4 but i want performance as well

 

That thing doesn't look like its gonna be fun to wrastle in there

 

Updated first post with pics and video!
