Exhaust setup for M5x

[M-technik-3]

The factory o2 location on OBD1 is right around the output shaft on the trans.

Most of us are well aware of that. We also know it chokes the exhaust which helps a bit with torque it's not great for a higher rpm engine.

Got yah, im just saying even though I had to shorten it it's in the same general area. Probably 4-6" closer to the engine.

Then I'll keep it in the front bank. Need to figure out where my vacuum leak is.
