Hey, nice work man! Looks good! I have rectangle stainless exhaust tips too I was going to run through the running boards like yours. I was curious how you mounted them? I was thinking about mounting mine directly to the running board so it doesnt rattle. Love these trucks on the ground!

I mounted the rectangular tips directly to the U shaped tunnel that I welded into the running board. I added a 10"-12" section of stainless "flex" to allow some movement so nothing cracks. There is about a 3/16" gap between the tip and the notch in the running board to allow some air movement for cooling, it didn't discolor the primer, hopefully won't hurt the paint either. I am going to Locktite the four 1/4 -20 bolts that hold the tips on as they loosened a couple times last year.

Good idea about adding the flex piece. I learned the hard way after a cracked tailpipe mount, I went back and added a couple of flex joints.

Looks great

Awesome thanks! I made the u shape inserts and got my running boards cut this weekend. Hopefully get the exhaust on soon..

Your truck came out spectacular!

Would you have a picture of the U shaped tunnel? Planning to go this route with my build and any help is greatly appreciated!
