Detailed Description

This Walker CalCat catalytic converter, part number 84281, is engineered for 2008-2015 Scion xB rear applications listed in the fitment data. The converter uses a stainless steel housing and ceramic substrate, with welded 2-bolt flanges at both ends to match the original exhaust layout.
