7-AFE Custom 4-1 Headers, UPDATE WITH DYNO CHARTS!! 56K Warning Options

ok well here goes;

My dad and i have been wanting a correct 4-1 header for our 7-afe for a long time, we have finally gotten around to making one. We used the plate that attaches to the engine from a Aerospeed header, so yes that was salvaged for parts. Then we had a shop bend up some pipes, all equal length. To be precise they are 37" long and they are calculated to be the length for the best performance gain at peak power, so then it falls right back into the peak torque and off you go again. So anyways, after about 3 weeks of work here is the result. All the welding except for the tacks in the before pictures was done by me, and the wrapping of the system was done by my father and I. The collector was purchased from Pegasus Motorsports, and the rest of the pieces were purchased or salvaged from our old 4-2-1 headers. Sorry for the number of pictures but i figured people would like to see it in detail from many angles. I am hopefully going to finish installing it on mthe car this weekend, so if i get a hold of a camera with sound ill try to take a sound clip of it with just the headers, cuse i know it sounded badass before it was welded. ENJOY!!!!!

OMG. I didn't recognize that one of the piping is bent in until I looked at this closer. It's bent becuz of the alternator? The alternator couldn't be that far over. I hope the results turn out great. I would love to mass produce my own designs and such but unfortunately I don't have the tools to do so.

well it is bent because of the A/C compressor, and i would have gotten rid of it but the car is a dd, so then i wouldnt have A/C in the summer, and MO heat is fing horrible , so thats why it had to stay on and the pipe had to be bent slightly. BTW just got the whole system can car back together, it sounds wicked and it also pulls a lot harder from 4-5500K rmp, thats what we were going for. For a 7-afe w/213k original miles, this little thing moves!...will update with some pics soon as i can.
