What is the deal with the tiny exhaust on the titans. I know they are imports but 2" pipes. All of the exhaust threads i have read have said to use 2 1/4" pipes, but the stock pipes measure 2" I.D., i see why 2 1/2" pipes kill low end torque. The reason for this thread is i picked up a 07 exhaust for my 04. One pipe looked bigger than the other, so i measured them, the stock side was 2 1/8" O.D. the modded side was 2 1/4" O.D. If i have a 2 1/4" mandrel bent exhaust built just like the stock 07 pipes will it out perform the JBA system?
