This is 1.5 but it gets crimped down to a inch...maybe less then goes in to the 1.25x3" flattend section..
anyhow....yeah i have a stillen race pipe thats supposed to come in today....I wanna see if it will fit the murano...I bought it used for 150 from some guy in the altima forums...It takes out the big cat at the end...so you still keep the 2 pre cats....

Actually if you have any hopes of staying emissions legal, you will need to somehow keep the stock cat. You can probably get away with losing the precats, but you'll fail emissions (esp in California) without a cat (even if they do not perform a visual inspection, your NOx CO2 will be very very high).
Really? I thought there were 3 O2 sensors on every VQ V6 engine - one on each precat, and one after the regular cat. The two sensors on the precats are called "front O2 sensors" and are distinguished by left bank and right bank. The rear one is just called rear O2 sensor. This I gotta check in the FSM...b0xdesigns said:
You know whats weird tho..is that theres no sensors after the last cat...Only at the two pre cats
