Product Details

AP Exhaust 7511 is engineered for the 1999-2003 Lexus RX300, front, where the OE exhaust system was built as a welded assembly. The aluminized steel construction is selected for exhaust durability and everyday service conditions. This part is used with the OE catalytic converter, and the factory system must be cut off 1-1/4" behind the O2 sensor port during replacement. AP Exhaust 7511 is a practical choice when servicing a welded front exhaust section on a Lexus RX300 and is identified by part number 7511 in catalog searches.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
