that was pretty funny. yeah, the exhaust setup makes no sense. why would a guy leave a 4' section of stock exhaust?

but rather than buying a whole new catback, i was thinking about replacing that stock 4' section of pipe (between the flange and the muffler) with another 2.5" section. That way, the whole catback exhaust will be 2.5" at that point, and i can keep the dynomax muffler. i like the sound of the exhaust right now because it is completely low key, and does not have that rice-boy coffee-can attracting-cops sound.

is it best to just get a universal carsound cat and have a shop fabricate the flanges and o2 sensor bung? i was going to have a shop do that along with making a new 4' section with 2.5" pipe. and the NEW OBX header is good. do you think i should get a whole new catback instead? even if i got a new catback, i would still have to get the carsound cat separately anyway right?. and i dont want to spend a lot.

well, do you think it was the exhaust causing the "sample diluted" problem from what you've read?
