Summit exhaust kit
No, not a nightmare to install. Actually, I thought it was easy. It wasn't perfect, but it was just a simple plan that worked well. Each pipe is for a side. Slide it in and work your way on back. When you get to the muffler, you a jack stand or milk create to hold up the muffler and then go over the axle and finish up.
Once you have it where you want it, tucked up and out of the way, clamp it down or weld it.
