Hey thanks for posting all of this info,
Do you happen to have a picture of the filter area near the drivers side muffler with the exhaust installed ? I am in the process of putting the lines in now. Doesn’t look like you can really get the filter far enough away from where the exhaust should be.
I had to cut my old 3” exhaust off because there was not enough room with the mufflers thst were on there and the way the shop who had done the exhaust for the previous owner routed and bent the exhaust .
