Just installed the SPD downpipe. The flow difference is apparent. Faster spool time and you can hear the turbo finally. The size difference is also significant.
Sure thing, it will be a generalized process.Any way we can get a quick step by step? Interested in knowing what the general process is.
Thanks for the write up! Very helpful. It honestly doesn't seem difficult, but I'm trying to visualize it and I just can't help but feel that everything would be such a tight fit to work in there. I also haven't spent much time in the engine bay either haha nonetheless it's good to know that it's pretty straightforward!Sure thing, it will be a generalized process.
1. Loosen exhaust clamp closest to the factory flex portion of the exhaust.
2. Unbolt the ridged mount that is attached to the transmission.
3. Loosen top two flange bolts from the top. 15mm wrench works for the passenger side top nut and a 15mm deep well with 3” extensions reaches the inwards upmost nut. Bottom nut can be accessed from below or above. Dealers choice.
4. Pull the flex exhaust portion out of its rubber pin mount and back to slip it off the factory down pipe. (This is a little struggle and I soaked it in lube to help.)
5. Unclip the O2 sensors from the hvac suction line coming out of the firewall. (Access from above and below moving the down pipe to aid in access.)
6. Unplug both O2 sensors one plug is up closest to the hood and the other is along the body on the passenger side about 18” from the turbo (about where your right foot would sit in the passenger seat.)
7. Factory downpipe can come out pretty easy if you arrange it right and watch for the O2 sensor wires as they will get caught up so don’t pull on it with any force.
8. The metal gasket is reusable and be carful to not bend it. It only goes on in one orientation so just keep flipping it until it lines up.
9. Take the O2 sensors off the factory down pipe and install them on the new one.
10. Install of the new down pipe is pretty straight forward from here. Just do the operation in reverse. You have more room to work now so it’s even faster.
Hope this helps!
Unfortunately, my better half has informed me that the truck is too loud.. hah. I think it sounds great with the turbo whistle and the nice run on deceleration. Sooo I’ll be selling mine at a discounted price of $400? Free shipping. Let me know if you want it and I’ll send it out.
