Out came the Sawzall. Cutting the tailpipe back a few inches netted an exhaust system that's tucked out of harm's way. "The stock muffler system actually flows really well," Shawn reveals. "We were still able to get an additional 7 hp and 10 lb-ft of torque out of the engine with our cat-back system." On the road and the trail, the Gibson-equipped FJ did feel faster, but it wasn't a night-and-day difference. No problem: We weren't expecting one. The biggest difference was the engine's new throaty note. Gibson managed to tune the sound to be aggressive and noticeable without becoming an obnoxious, overpowering din. We appreciate the additional power output, dig the sound, and love the extra ground clearance.
