Finished the exhaust on Wednesday this week. Didn't get a chance to upload pics till today.
Ended up going with the single exhaust run. After a lot of test fitting and head scratching there was just no way I was going to be able to get a second pipe over the rear axle on the passengers side. The way the pan hard bard runs across there and the spring and spring seat sits on the axle there's just no room. The only way duals would work is if I could dump them out the sides before the rear wheels which would look stupid on anything but a drag car. I had to be content with fabbing a Y pipe and going with a single exhaust. The 2.5" will be more than enough for the small stock V8 in the car.
Here's pics of the finished product laid out on the garage floor before I bolted it all up:
Y pipe was a bitch to make. Spent about an hour grinding that into the shape I needed to fit to the drivers side pipe at a nice angle.
And here's a pic of what I think are probably the 3 best welds I made on the whole project:
What I found was not having a belt sander or band saw to cut the pipes and get a perfectly flat cut was making the welding difficult. If the two pieces did not fit together perfectly with the same size seam all the way around, I would end up burning through the metal if there was a slight gap. To get around this I would lay down some bead on either side of the gap first to make it thicker and then go back over the middle of it. Made for uglier welds but it worked. Nobody is going to see it anyway as its going to be under the car.
Thanks for all the input, I appreciate it. I'll post some pics up of the floor pans when I get to those in the project thread.
