Alta Cat Back Exhaust
Peak wheel-hp: 170 @ 5600 rpm
Peak wheel-torque: 187 lb-ft @ 4400 rpm
Maximum wheel-hp gain: 4 @ 4450 rpm
Maximum wheel-torque gain: 5 lb-ft @ 4400 rpm
*Install process: This involves cutting the factory exhaust just behind the second catalytic converter and installing the supplied clamp-on adapter. The center and rear section are held together with high-quality V-band clamps and use the factory hangers. The entire process took less than 45 minutes using a lift and power tools to cut the factory system.
*Pros
Factory-like build quality and better-than-factory looks Makes a deeper, throatier sound without being much louder than stock-and no drone
*Cons
The catalytic converters seem to be the real bottleneck, not what's behind We'd recommend installing Alta's downpipe at the same time
Price: $729.99
*Notes: We're impressed with the quality, sound and ease of install, but to really get the full advantage in terms of power; we recommend buying the full turbo-back exhaust. It lost a couple of hp at peak power, but created a bigger surge in the midrange.
