Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.
