I am still researching.
Unfortunately I know of no BMWs let alone a X5 to get some input. The best place for HP and flow benefit should be where the down pipes curve toward the back but I have to make sure that both are at the same length from the heads and I don't want to circumvent the pre cat sensors if I am going to light up the dash or lose control of the air/full mix.
If I install them further downstream any gain is more likely torque and less HP. I don't want more torque on the low end. I am where I want to be for launch. There is room to install them after the pre-cat sensors and before the cat and that may be the only option. I would rather not do that because of the loss of flow.
I think the place where I get the bottle filled will be able to answer my questions from their experience with domestic cars if I let them do the install. Bottle is almost down to where I can't heat it enough to get the gauge in the green zone so I will talk to them soon. Phone doesn't work with them.
I have spoken to a custom muffler shop in Lewisville that will do the welding if I find the only 'benefit' is lots of noise or if I become comfortable where they should be installed. I have some concern about the risk of setting myself on fire or going deaf or not liking how it sounds if I don't add a pipe to move the exit point. I don't want it to be visible and they would be able to make the pipe while I am there for the welding.
