    The two 45s I ordered showed up. I think I have a fairly good idea how this is going to work. I will have to trim the black y collector as well as the old exhaust. That way I can get the two 45s to line up just right. My concern is the accuracy of mocking it up and getting it just right. If anyone as some advice how to make sure fitment is great I'd appreciate the advice.

    I think the color is technically called "burnt bronze". I've been trying to decide and still can't come to a decision, because right now I'm leaning toward the "burnt bronze" color they offer.

    Edit: if you google "cerakote burnt bronze exhaust" you'll see some good examples.
    Oh yeah, that could look good.
    The color reminds me of hard anodization of aluminum

    I went with an anthracite grey (paint) on my manifold, I think they look pretty good

    Is it possible to move your cat backwards a bit? I think this would give you some more play room to get all the angles nice and smooth
    yea i think what i'll do it chop it at the catalytic converter and route it from there. I needed to set this up to see exactly what changes needed to occur before buying piping. i will also need to add the mount to the y-collector that i removed off the stock portion. It will be a good amount of welding ahead of me, but once it's done I should be done and be able to drive the car. I will be taking in the headers this week to get ceramic coated, but I cannot decide on a color. I was thinking of a 50/50 mix of black and gold, but now i'm kind of leaning toward just a silver since that's the general theme in the engine bay already. What do you think?

    Working on the exhaust. I'm gonna need to puzzle this together. I can cut back to the cat and then from there I need to figure out what looks like two 45 degree angles and the straight to get this connected. I shouldn't be the worst thing I hope. Cool picture of the 6-2-1 exhaust.

    I got these little morsels installed. Biggest pain in the ass to get the sheered off bolt out. I ended up just having to drill the whole thing out and retap the remaining bolt out. They are in now and look pretty. Lubed with all the molly, lol. Gonna take the headers in for cerakoat this week.

    The internet makes this all seem so easy! I think what I am going to do is band clamps where the y collector attaches to the headers and then a vband on the 3" single outlet. If it comes to it I can probably add in the vbands for the collector as well, but I don't think it will be necessary. I'll keep you posted. I just ordered the vband and clamps to get it all mocked up.

    The headers are just mild steel, so if you don't coat them they'll just rust. And most "header" paint doesn't last. I'd ceramic coat them after you have your flanges welded on. You should just weld the Y to the collectors and put one VBand after the Y pipe

    Are you gonna ceramic coat them?
