Exhaust is one of those things that gets hashed out every other day on forums so I'm not going to detail it all that much. But here are a few things to consider:

When doing this project you need to figure out up front what's going to be more cost effective or worth your time. If you are doing an off the shelf turbo manifold you may be able to secure an off the shelf exhaust system. I would highly recommend spending the extra money and going that way if you can. Remember though if you are planning on keeping the 6PI you'll need to manufacture your own turbo manifold. This means no off the shelf exhaust system will work for you. Which means you'll have to spend extra time to hunt down materials and find persons or tools that will enable you to accomplish what you need done.

By this same token you can hybridize the two. If you do construct your own turbo manifold you can easily construct a down pipe that can connect to a custom mid pipe. This mid-pipe will then need to connect to an off the shelf cat-back system. This will probably provide you with the least amount of headaches... and may be a route I eventually choose to go with. As it stands however I found it significantly cheaper to manufacture the exhaust myself buying off the shelf universal components. Stores like Racing beat and summit-racing are indispensable when doing the exhaust that way.

If you choose to build your own you will need to figure out exhaust sizes for your HP/Trq Goals, and locate a dealer that can supply you with the proper materials. Mandrel bending will flow much better than crush tube bending and may prove to be the exactly what you need. I recommend the vendors on here as they are very helpful and more than likely have the parts or materials you will need.

Of consequence if you choose to manufacture your own Turbo Manifold you will need to plan it out before you weld all the pieces together. I was lucky and had access to CAD software and built a digital model of mine prior to even making the first welds. On top of that, I was able to test fit prior to each individual part of the manifold in that I saw that my original blue prints could not function how I wanted them too. The off the paper revision caused me to move the wastegate runner to the underside of the manifold rather than on the top. As it stands it functions rather well without much issue. Further details on constructing your own manifold will be presented later.
