The full breakdown.
MBRP · Cat-Back · T304 Stainless
What This Does
The MBRP S4704304 replaces your factory cat-back section with mandrel-bent 3-inch tubing routed through the factory hanger locations. No cutting or welding — bolt-on install at home with hand tools and a jack.
No tune required and no check-engine light: MBRP cat-backs leave the catalytic converters in place, so emissions stay intact while the system opens up the sound and flow path.
What It’s Made Of
Built from T304 stainless steel — the most corrosion-resistant grade MBRP offers, fully welded and sealed at every joint, and backed for the life of the vehicle.

— Why we stock MBRP
A bolt-on cat-back our customers actually finish in their own garage.
MBRP builds a true bolt-on system — mandrel-bent tubing, factory hanger locations, and every clamp in the box. Most enthusiasts have this on in an afternoon with hand tools. Prefer it done for you? Drop the car at our Thousand Oaks shop and our techs will handle the install and a fitment check.
We sell MBRP because it does what it claims: real sound, real build quality, and a warranty MBRP stands behind. No surprises.
