I was noticing on my x that there are 4 cats in the exhaust stream with at least 2 upstream o2s and 1 downstream o2. I also noticed the distance from the right bank to the first cat is way shorter than the distance from the left bank to that first converter. Just curious if anyone other than me thinks this could cause different backpressures on each bank? Anyone experiment with exhaust options from manifolds/headers back to muffler fairly cheaply or just buy a cat back exhaust for a little more performance and sound plus fuel economy? Thanks for the answers in advance.
