Exhaust

Three Questions Decide What Fits

• Which engine? The 1st gen Tundra came with a 3.4L V6 or a 4.7L V8. Every header kit on this page is 4.7L. Some complete systems cover both.
• Which year? The headers split at 2004/2005 — there is a 2000-2004 kit and a separate 2005-2006 kit. They are not interchangeable.
• Which cab and bed? Exhaust systems are routed to the truck, so a kit listed for an Xtra Cab short bed will not fit a different configuration. Check the listing against your truck, not just the year.

Where to Go From Here

• Headers — JBA kits for the 4.7L. The factory manifolds are the restriction worth removing first.
• Cat-back systems — complete bolt-on from the converter back.
• Catalytic converters.
• Mufflers and resonators — for setting tone on a custom system.
• Weldables — bends, flanges and tubing if you are fabricating.
• Gaskets and hardware and odds and ends.

Headers — Pick Your Year, Then Your Coating

JBA designed these around the same premise we would: the factory exhaust manifolds on these V8s are restrictive, and that is what keeps the engine from its potential. All of them are listed for the Tundra and Sequoia 4.7L.

2005-2006:

• JBA header kit, silver ceramic
• JBA header kit, stainless steel

2000-2004:

• JBA header kit, titanium ceramic
• JBA header kit, silver ceramic
• JBA header kit, stainless steel

The coating is the price difference, not the flow. Ceramic keeps heat in the pipe and out of the engine bay; bare stainless is the cheaper way to the same port design.

Complete Systems

• Magnaflow exhaust, 2000-2006, 3.4L and 4.7L — single exit, listed for Limited and SR5. The one system here that covers both engines. Mandrel bends throughout, OEM-style barbed hangers, a straight-through stainless muffler, and dyno-tested for the fitment and the gain.
• JBA exhaust, 2000-2006 4.7L, Xtra Cab short bed — note the cab and bed restriction before ordering.

Catalytic Converters — Emissions Note

The direct-fit converter here is listed as 47-state smog legal and not legal for installation on California, Colorado or New York emissions controlled vehicles. It is listed for the 3RZ and 5VZ, so it is the 3.4L V6 part. Measure before ordering, as there is more than one factory configuration.

Mufflers and Resonators

LCE Pro Flow mufflers in 2 1/4" and 2 1/2", 14" and 18" bodies, three-chamber and straight-through, satin finish — the building blocks for a custom system rather than a bolt-on kit. Exhaust wrap is on this page too.

Tell Us the Truck

Year, engine, cab and bed — with those four we can confirm a header and a system that actually bolt together. Get in touch via our contact page. The rest of the truck is in the 2000-2006 Tundra catalogue.
