A little off topic but i was kicking around the scrap yard today and saw an upside down Nissan with 1" fence pipe welded under it for exhaust...

 

FYI.. Speedway Motors offers a mandrel bent, U-weld, 2.5-inch tubing kit for $140. That's a helluva deal these days.

Add mufflers of your choice and have at it.

 

My 75 parts truck came with a new LMC exhaust still in the box. I had a shop install it. They had to do a considerable about of bending to get it to fit and hang right. I didn't pay for it, I would have returned it if I had.
