66 exhaust routing

[WorldsCrappiestTruck]

With a rear tank, lowered and wanting a rear-exit, it was a challenge. Add to that wanting a relatively quiet truck.

I have an LS, Speed Engineering headers, to 8” Flowmaster universal cats, then a 2.5” stainless system from there. The pipes were a kit, and elbows/45’s etc from Amazon that I cut & welded sections together to route accordingly. The mufflers were Jones Exhaust from summit which I LOVE. They are super quiet at idle, have a nice tone going down the road with zero drone, but blatt loudly at WOT.

Fabbing all this up was a challenge but I’m very pleased with the result.

That is a great job on running that exhaust. I took the easy way out and dumped in front of the axle.

Thanks. I considered it but put dumping in front of the rear axle, or in front of the rear tires as an absolute worst-case-scenario bailOut option, if I simply couldn’t fit over under and around the trailing arms, axle, panhard bar and tank.

Yes, there are a lot of added degrees of resistance with all the bends….and I’m sure the theorists decree I’ve lost HP, but that wasn’t the goal.

Goal was quiet-ish, rear-dump behind the rear tires, and no smell (hence the cats). All three boxes were checked with this setup.
