It's been a while since I've updated here I'm always just dropping pics on Facebook because it's easy and I'm lazy LOL.
Anyway here are a few of the rear diffuser progress.
You can see the two outside corners they are air catches for the rear tires so they will not be filled in like these pics they will be a straight through thin walled design when complete. We are designing not only for form but function.
Instead of the plain round tips I have decided to do a double walled more refined tip for a higher end look to match the truck better.
Here are the cad drawings of the tips. You will only really see the green and brown part on the diffuser we are boxing the entire exhaust system in so only the tips will show sort of like a high end exotic.
