Xforce 3" Turbo Back Exhaust System (409 Stainless) – Toyota Land Cruiser 80 4.2TD 1HD-T / 1HD-FT (1990–1998)

Make your 1HD-T / 1HD-FT breathe properly. The Xforce 3" Turbo Back Exhaust System is built for the Toyota Land Cruiser 80 Series 4.2 Turbo Diesel (1990–1998), delivering a major reduction in post-turbo back pressure for faster spool, lower EGT (exhaust gas temperature) under load, and a stronger, smoother driving feel.

This is a true turbo-back system (not just a rear section). It replaces the exhaust from the turbo outlet back to the tailpipe for maximum flow where it matters most.

Why a 3" Turbo-Back on a Land Cruiser 80?

• Lower restriction after the turbo = improved turbine efficiency and response
• Lower EGT under load = less heat stress when towing or climbing
• Better driveability = smoother boost delivery and mid-range pull
• Future-proof = supports common intercooler/turbo/fuelling upgrades

Key Features

• Full 3" (76mm) turbo-back exhaust for maximum flow
• 409 raw stainless steel construction for durability and service life
• Touring-friendly note with a deeper diesel tone (not harsh)
• Designed for LC80 4.2TD platforms where flow and EGT matter

Vehicle Compatibility

• Vehicle: Toyota Land Cruiser 80 Series
• Engine: 4.2 Turbo Diesel 1HD-T / 1HD-FT
• Years: 1990–1998
• Use: touring, towing, off-road and performance builds

Build It Properly

If you’re improving performance or towing capability, these upgrades help balance the build:

• Suspension Lift Kits – stability, clearance and load control
• Premium Brake Kits – better stopping under load
• Protection Equipment – underbody safety for touring and off-road

Customer Use Cases

• LC80 towing caravans or heavy trailers across long distances
• Touring builds chasing lower EGT and better response on climbs
• Intercooler + mild fuelling upgrades where factory exhaust becomes a bottleneck
• Reliability-focused setups want reduced heat stress and smoother flow

FAQs

1) Is this a full turbo-back system or only a rear section?
This is a full turbo-back system, replacing the exhaust from the turbo outlet to the tailpipe.

2) Which engines does it fit?
It’s designed for the Land Cruiser 80 4.2 turbo diesel engines 1HD-T and 1HD-FT (1990–1998).

3) What real-world change will I feel?
Most owners notice improved response (earlier spool feel) and smoother mid-range pull, especially under load or when towing.

4) Does a 3" exhaust help EGT?
Yes. Reduced back pressure after the turbo typically helps lower EGT during sustained load (towing, hills, heavy touring weight).

5) Is 409 stainless “good enough” for UK weather?
Yes. 409 stainless is widely used in performance exhausts for its durability and corrosion resistance in everyday use.

6) Do I need tuning to run this exhaust?
No. It can be fitted to a stock vehicle. Tuning can maximise gains, but it isn’t required.

7) Will I need brake upgrades if I’m towing?
Not mandatory, but strongly recommended for heavy towing or performance builds. Consider our Premium Brake Kits.

8) What’s the smartest next upgrade after the exhaust?
For touring builds, suspension and protection are usually next: Lift Kits for load control and Protection Equipment for underbody safety.
