I have the old exhaust and manifold out of the truck. I have the head studs in and the gasket and header in place with nuts finger tight. I also have the muffler and tail pipe on the hangers. The pipes in between have me a little puzzled.

(1)I have two pipes with o2 sensors mounting holes? My original exhaust had the o2 sensor befor the cat.

(2) Dose any one have pictures of lc engineering exhaust and header installed from the under side of the truck?

Call John in tech at L C Engineering he can tell you exactly what the pipes are for. One pipe might be for an exhaust gas temperature sender. I have an LC Engineering header but custom SS exhaust.

No worries. Got it all together. Hope the exhaust tone quiets down.

Doubt it will quiet down, but you'll get used to it
