Product Description
Overview
The MBRP S6285AL 4" Installer Series cat-back exhaust is purpose-built for 2004–2007 Ford E-Series vans equipped with the 6.0L Power Stroke and factory catalytic converter. This system frees up backpressure for better throttle response and a deep, mellow tone while retaining OEM emissions equipment. Heavy-duty aluminized steel delivers strong value, and the single side exit tucks cleanly along the body for fleet-friendly ground clearance.

FAQ
Will this fit my Super Duty pickup?
No—this S6285AL kit is for E-Series vans (E-250/E-350) with the 6.0L. For F-250/F-350 trucks, see our 6.0L Super Duty MBRP systems in the 2003–2007 category.
 Does it replace the catalytic converter?
No. This is a cat-back system that keeps the factory converter in place.
 Is welding required?
Typically no. MBRP designs these as bolt-on kits using factory-style hangers. Always review the instructions for your specific van.
 What tip should I use?
Popular choices include the polished MBRP T5052 or the black MBRP T5157BLK depending on style and inlet size.
