Header Build
Posted: Wed Sep 28, 2011 10:24 pm
Had this in another thread, but figured it could use it's own build thread.
Got a hold of the flanges yesterday, so have been able to make some progress on these. First and foremost, I have to figure out how to get the tube into a D shape for the flanges...
After some thinking, I came up with this...


Works pretty good too...


After a lot of cutting, test fitting and tack welding; I have the first primary (cyl 2) of the build routed to where they will join with the rear primaries.



Then a little while later, I worked on the second primary of the build.

and this is where I ended tonight because of lack of bends remaining.

More bends arriving tomorrow, so shouldn't be too much of a hold up on progress. Also need to figure out where to get a 3 into 1 collector. Looks like I'll more then likely have to have one custom made.
The design I am going for will hopefully produce an exhaust similar to this...

The goal is to try and get the pulses to perform in an even interval through the exhaust. Which could possibly yield better results then a standard header. Even if all it does is makes it sound better, oh well. I think the sound they produce is much more refined, and would definitely get a few people curious when they hear it out of a Beretta of all things. Still hoping I will see decent numbers when i get a chance to dyno the car. Never know for sure how much the headers help, being I don't have any baseline numbers of any sort. Either way, if I'm going through the work of building them, might as well try to get as much as possible out of it.
What got me interested in this was a topic over on 60v6. bob442 built a set like this for his high comp N/A build in a Monte Carlo. The Beretta has a little less room, but I'm going to give it a shot. So far, things are looking pretty good. Will have to do some heat shielding by the clutch slave cylinder, steering rack and probably wrap the shift cables with something. Going to get started on the rear header tomorrow, which are going to be interesting to figure out.
