FAQs
What exactly does UT4001 do?
UT4001 is the connector/mount kit that transitions your existing 4" performance exhaust to a single vertical bed stack on a full-size pickup. You add the stack (and tip) you prefer.
Will it fit my truck?
Yes—it's a universal kit for full-size pickup beds. Minor cutting/positioning is typical to route and secure the stack safely. It’s intended for trucks already running a 4" performance exhaust.
Do I need anything else to finish the install?
You’ll choose the actual vertical stack and any finishing tip. For dual stacks or 5" systems, see the MBRP cross-references above for the correct T-pipe or 5" kit.
Is it aluminized steel or stainless?
UT4001 is aluminized steel for value and durability. If you want stainless components elsewhere in the system, pair UT4001 with the stainless tips or stacks you prefer.
How long does installation typically take?
Most driveway installs are a few hours with common hand tools. Mock up the route first, then mark and tighten in final position.
