Got the exhaust run, its not how I would have done it but I think it will work, He actually googled longarm exhaust setups for jeeps and ran it under my upper, but he had to account for full droop in the rear, so it hangs down about even with the bottom of the frame to go under the upper. Either way, I think it will be fine, but it may see a rock one day. The sound is much better with the 2.5" tubing, i had 2" before I think.
