Full Tilt Performance | CAT C15 / 3406 Ceramic Coated Exhaust Manifold (Peterbilt & Kenworth)

Full Tilt Performance 88002 Exhaust Manifold

CAT 3406E & C15 – The OG That Still Runs the Game

Before everyone and their cousin started casting “performance manifolds,” this was already out there making power and not cracking.

The Full Tilt 88002 CAT 3406 Manifold isn’t new. It’s proven. And in this industry, that matters.

Built by the Hummels from scratch, this is the manifold that showed the CAT world what proper exhaust flow actually looks like. Not a catalog copy. Not a rebranded casting. A purpose-built upgrade that changed the standard.

Why This Thing Still Dominates

Most factory manifolds are restrictive, heat-soaked, and eventually turn into a warped, leaking mess.

The 88002 fixes all of it.

• 3-piece design allows expansion and contraction without destroying itself
• Hand ported & polished runners move exhaust the way they should
• Chrome ceramic coating keeps heat where it belongs (and out of your engine bay)

Result?
Faster spool, lower drive pressure, cleaner power, and less stress on everything bolted to your head.

This isn’t theory. This is what guys have been running for years because it just works.

Built Like It Matters

No corners cut. No cheap hardware. No “good enough.”

• Comes standard with ARP stainless hardware
• Designed to survive real heat cycles—not dyno pulls and Instagram posts
• Proven on working trucks, not just weekend builds

You bolt this on once and move on with your life.

The Bottom Line

There’s a reason this manifold is still around.

It wasn’t built to be trendy—it was built by a trucking family to work, and it still does.

If you want something proven, durable, and actually worth your money, this is it.

And if you’re buying it from Momentum Worx, you already know how this goes:
No junk. No guessing. No games. Just parts that do what they’re supposed to.
