2004 Honda s2000

Pros
The Skunk2 racing cat-back exhaust system is constructed with T304 stainless steel mandrel bent tubing to ensure maximum flow over the factory unit. Designed as a true cat-back exhaust system for the Honda S2000, the Skunk2 Mega Power exhaust features dual 110mm diameter polished tips with an acid etched Mega Power badge and a serialized nameplate.

Cons
While the installation of the new exhaust was a simple procedure, the removal of the factory exhaust required us to spray the rubber exhaust bushings with plenty of grease. The S2000's one-piece exhaust design is a mechanic's worst nightmare, if you're attempting to remove the unit on your own. Receiving some assistance when removing the exhaust can help speed up the process.

Notes
The Skunk2 Mega Power Exhaust enabled the 2.2L engine to breathe additional power into the roadster as both horsepower and torque were increased throughout the powerband. Peak output over our baseline run netted an increase of 7 hp and 5 lb-ft of torque by simply bolting on the new exhaust system. Dyno graphs show a slight loss in horsepower from 2,200 to 4,200 rpm but picks up with a gain of 5 lb-ft of torque and 4 hp from 4,300 to 5,600 rpm. Our largest margin of gain was recorded from 7,500 to 7,800 rpm with a gain of 7 hp and 5 lb-ft of torque over baseline.
