No you are way off and won’t have enough length to make that work. Your first pic is correct at routing to get out of the side sill. There is a small hole were you can pass through to get to the tunnel area around were the factory harness is. You have to look for it but you don’t go into the engine bay then down.

I’m getting ready to put a set of M&M’s on with cats and I don’t recall there being any documentation about needing o2 extensions? I don’t think the cats have bungs after either. I think the primary tube has upstream and maybe the collector houses the downstream? Anybody done M&M’s on Gen4 that can clarify?

Mm secondary 02 are on the collector where you would bolt the exhaust up to

When I installed full Belanger headers/exhaust on my 04 the instructions looked wrong….but after rechecking they were correct and the cabling reached. I am not sure on the 08 but if you check with Belanger they will send instructions if you do not have them.

I’m installing Belanger headers on my 08. I wanted to know if I am routing the o2 sensor and extensions correctly. Is the o2 wiring supposed to go through through the engine bay?

Downstream o2 routed as described in Belanger instruction.

Passenger Side o2 wire is routed up the firewall and under/next to the coolant overflow tank (wrapped in gold tape)

Driver Side o2 is routed next to the brake/clutch line

Is there a better way to keep the connectors and wires away from the headers?
