I was just notified that my headers are done and on their way! Instead of building my own headers and learning through trial and error, I decided to have GP Headers build them for me. The offer a kit that includes headers flanges, collectors, aluminum hinges, PVC elbows and self tapping screws. After you purchase a stick of PVC straight tubing, you build your PVC mock up headers the way you want them. Once you're done, you ship the mock up headers to GP and they reproduce them in the material of your choice and ship them back.

I opted for stainless construction with merge collectors. They should be here Tuesday. Once I get them in I can finish the exhaust system and be another step closer!

Never heard of GP Headers before so I checked them out. Nice!
One can appreciate the breakdown of materials costs for someone thinking DIY. I've seen other mock-up kits for headers before. Their custom kit is a great idea.

A really long time ago I read an article about a company doing this. When I started thinking about it, I couldn't find the company so I resigned myself to building my own. Then two people I know on Facebook posted about their new headers etc, etc. Talk about good timing!

I went to PRI last fall and after talking to the GP guys and I was sold.

It came down to spending close to $1200 plus for a kit, then making numerous mistakes because I've never done it before, ordering more tubing to replace what I tossed in the trash can, make more mistakes because I don't know the tricks and processes, so on and so on. If I were to have done it myself, I probably would have spent just as much money and a lot more time!

Exactly & that's why I mentioned an appreciation that they listed an average costs on the materials.

I did my CC duallys exhaust w/stainless excluding the headers. I got my material free from a scrap/demo barrel where I work. I picked through the barrel daily searching for various 90's, 45's, & straight sections in the sizes needed. I had to cut all the elbows but I figured it would be do-able by just cutting on the weld line & keep things as true as possible. But, w/each of those pieces just slightly off/different caused me to go through a BUNCH of extra work trimming/buzzing things for the right fit. That was the only one I did w/used bends LOL. The next one I did using new bends & cut straights..... So much easier & better. The bends weren't free but I get them for much less than NET pricing I looked up & I used food/medical grade stuff.

Yours came out great & the best part is you know they'll clear all your mods.
