XFORCE Exhaust systems for Holden Commodore VE/VT/VX/VY/VZ Review

[Matespace]

Xforce exhaust (http://clixtrac.com/goto/?43522) systems are designed to be a true bolt-on option and power gainer. All exhaust systems are R&D in-house and dyno tested with proven power gains. 304 Stainless steel mandrel bends and flanges are used in the construction for its strength, excellent heat resistant, rust proof, high flow (mandrel bends) and finish properties. Everything in the Xforce range includes nuts, bolts, gaskets and everything else needed for a true bolt on experience.

Xforce recommends a dyno tune after an exhaust item has been upgraded (like any other power mod) to fully utilize its power potential.
