Uncertain.. keep an eye on it!My down pipe is installed. Wasnt to bad of a job. sounds good with my gibson duel exhaust. nice power increase. No codes after 15 miles. How long does it typically take to throw O2 codes? Just wondering if I'm out of the woods.
I agree, especially with the idea of getting insulation wrap back on it to keep efficiency up. Could lead to rust out.I'm not sure I like the material choice, it looks like aluminized steel whereas the stock one is decently high grade stainless. I'll wait until something comes out in at least 304.
All the more reason for heat wrap.Those damn coolant hoses are in the way
I’m currently installing my AFE catless downpipe and could only find this thread with a step by step guide or any info at all regarding this install.. I’m not trying to hijack the thread. I’m just trying to help anyone else who will do this install.
For all three nuts I used a 15mm ratcheting wrench. All three were tough to break.
the nut closest to the motor, the wrench could only really lay one way. Across the turbo and pointing towards the passenger side of the truck. This one was the hardest of all three. I really had to nearly hover over the engine bay and pull up.
the nut on the passenger side was easy. Have the wrench pointing down and pull towards you.
bottom nut is straight forward, but kind of hard to get any tq on it. Gotta grunt and hit it hard.
I took pics of the wrenches position for each nut. Hopefully this can help someone.
I dont have a pic but you have to access the plug from under the truck. It’s one of those do it by feel not by sight maneuvers. There is a round clip/ retainer on the O2 wire that holds it out of the way, find that and free it/ unclip it and you have more O2 wire slack to play with.After 6 weeks mine finally came in. Thanks for the pics. Passenger side nut, easy as pie. Engine side nut, I had to go to Lowe's and get a breaker bar that fit around the ratcheting wrench and eat dinner. I will resume the job tomorrow. It should break loose tomorrow. I have not tried the bottom nut yet.
Do you happen to have a pic of where the bottom O2 sensor plugs in. I have tried to trace the wire and it disappears under all of the hoses and pipes. LOL.
I have the exact wrench BTW.
I should have my DP and Exhaust during next week. I can let you know how it fits up.Has anyone that put on the SPD DP also get the SPD cat back exhaust? The clamp provided is too big and will not tighten enough to hold the exhaust pipe in. Not even close. I know it has an adapter for stock exhaust and the clamp fits the adapter fine. The other extra clamp does not get tight enough to cinch down.
