Default Fabricators!

Who lives in VA or NC that could potentially help me out with a fairly simple manifold project? I need to take a stock 08 exhaust manifold and chop the primaries much like my last El to UEL conversion. I would do this myself but I have moved and all the toys (tools) have been sold so no more fun on demand.

I'll pay just need a welder and maybe some 1.75' mild steel 16.ga tubing. What I want to do only takes about an hour so let me show you then you can comment:



My first time around i took this stock unit and modded the driver side primaries. Since I no long have any welding equipment I want to modify the passenger side primaries to make them shorter. I found that modding the driver side primaries didnt produce the results we were going for (UEL). So the way I viewed it while on the bench was simply chop out the curved sections near the flange and replace with straight tubing OR make them longer.

They are 25 inches long stock I was thinking about adding 6" to each primary to throw it out of phase and get a nice rumble. This is just a idea thats been in my head and since I have two spare 08 manifolds I figured i need to do this to satisfy myself and see how well it works.

my first version looked like this :


I was happy it gave off a EL sound but with a slight difference around 3500-4500RPM I just want to take what you see there and either lengthen or shorten it to get what I had in mind. For the fabricators out there if you have a better way or agree with anything ive said let me know or if you can help me that would be nice as well

Also the driver side primaries are 21 and 19 inches from the flange to the collector i would like to keep the overall locations intact(cat, three bolt flange, o2 bungs) and modify the tubing like last time. Afterwards it all gets wrapped and sprayed
