I am currently pulling a Cruiser Funfinder 16" camping trailer (2200 lbs dry) and want to increase my power and torque. I am going to put a catback exhaust system on my 2001 Santa Fe with the 2.7 V-6 with AWD. I am going to remove the resonator and increase the pipe to 2 1/2 and install a performance muffler. Has anybody done this to their Santa Fe? What were the results? Please let me know.
