I removed my aftermarket o2 housing/downpipe and am planning on installing the stock ones. Was wondering if there are any tips when doing so. Do you recommend that I connect them before installing so it's one piece or do the o2 housing first and then the downpipe?


Thanks!

 

It’s o2 housing then down pipe. Install them separately.

 

downpipe from the bottom, radiator+ assembled manifold/turbo/02housing from the top of the engine bay
