After reviewing various catback exhaust systems on my Jeep TJ, I settled on this system for the best value for money to meet my desired goals, ease of installation, sound , performance and overall rating to achieve. Although I have Banks Torque Pipe headers, I originally gravitated towards Borla even though it was more expensive. The sound after all this was installed dispelled all hopes for fuel economy :) Easy installation of a quality kit. Great tone and exhaust sound without being too loud.
