The full breakdown.
1999-2004 Ford Mustang GT · 4.6L V8 · 2.5-Inch Mandrel-Bent Cat-Back
What This Does
Street Profile is MBRP’s daily-friendly tune — a deeper, fuller tone a clear step above stock, civil enough to live with every day and drone-free at highway cruise.
The 2.5-inch mandrel-bent cat-back replaces the restrictive factory exhaust from the catalytic converters rearward — every section sized for flow, exiting dual split rear through 3.5-inch dual-wall tips.
What It’s Made Of
Built from aluminized steel — a durable, cost-effective build at MBRP’s most accessible price point, backed by a 3-year warranty.
Mandrel-bent 2.5-inch tubing holds full bore diameter through every bend, so flow stays consistent end to end.
On The Vehicle
MBRP’s cat-back exhaust on the 1999-2004 Mustang GT — installed and on the road.

— 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.
