Manta 2.5in Exhaust - Nissan Patrol GU Y61 4.5L TB45 Petrol Wagon 1997-2001

The 4.5L TB45 is a willing motor held back by a very restrictive factory system. Whether you go cat back or take the full kit with extractors, a 2.5in Manta setup is where every TB45 build should start.

Choosing your system

• Full System — the lot, from the engine back, including extractors where they are part of the kit. This is where the real gains are.
• Full System - No Cat — the complete system with the catalytic converter left out. Off-road and competition use only.
• Cat Back — everything from the catalytic converter back. The factory cat and engine pipe stay where they are, so it is the simplest road-legal way to open the exhaust up.

The options without a catalytic converter, and any DPF replacement, are sold for off-road and competition use. Removing emissions equipment from a road-registered vehicle is not legal in any Australian state. If the vehicle is registered and driven on the road, choose an option that retains the cat or the DPF.

Aluminised or stainless

• Aluminised Steel — Manta's standard. Aluminium-silicon coated steel, pressed and mandrel-bent the same as the stainless, and it will give you years of service in normal conditions. Best value of the two.
• Stainless Steel — 409 stainless. Worth the jump if you live near the coast, spend time in mud and dust, or do river crossings. It will comfortably outlast the truck.

How loud do you want it

• Quiet — the most muffling Manta offers. Deeper and cleaner than factory, but still civil on a long highway run.
• Loud — straight through. The most aggressive of the three, and you will hear it at cruise.
• Medium — a resonator in place of one of the mufflers. More note when you get into it, without the drone that ruins a road trip.

Fitment

Nissan Patrol GU/Y61, TB45E, 1997 to 2001. Bolts to the factory mounting points and uses the standard hangers — no cutting or welding.

2.5in pipe throughout, and every bend is mandrel-formed. A mandrel bend holds its full diameter around the corner instead of crushing down the way press-bent tube does, which is the whole point of fitting a bigger system in the first place.
