Description
This exhaust system is part of our MIJ Performance Exhaust range — designed, developed, and hand-built in-house by our skilled technicians.
We don’t resell or rebrand generic systems — every exhaust is crafted to order using premium T304 stainless steel, ensuring a perfect fit, exceptional durability, and performance you can trust.
When you buy from us, you’re buying direct from the manufacturer, not a middleman.
Direct Fit Exhaust System For Rover MG ZR 1.4L (Petrol)
(Not compatible with estate)
Designed to fit after the cat
What you get: Middle and rear sections of the exhaust
Exhaust gaskets/fittings not included
Please note: The tailpipes may vary slightly – depending on stock
What “Direct-Fit” Means
When we say Direct-Fit, we mean this system is designed to bolt or clamp straight onto your vehicle using the original mounting points — no cutting, welding, or modifications required.
This system replaces your middle and rear sections as one complete unit.
We do not sell this system as separate parts. It is sold as a full, complete exhaust system only, engineered and tested to work together as a matched setup.
REPLACE IT ONCE — NEVER AGAIN
This is our own brand exhaust system.
We are an established exhaust manufacturer — buy with confidence.
Key specs:
- Hand built in the UK to the highest standard
- Made from T304 stainless steel
- Anti-magnetic material
- Much less susceptible to rust compared to mild-steel systems
- Full-flow mandrel bends for excellent gas flow
- Free-flow design for increased power & efficiency
Why free-flow matters
All of our exhausts are free-flow systems — meaning minimal internal restriction.
Factory/OEM silencers contain chambers & baffles to reduce noise — this slows the gas speed and increases back-pressure.
Our systems remove these internal restrictions → improving exhaust velocity & engine breathing → resulting in measurable performance gains.
Each system is built & set up to suit this exact model, based on our own research, development, and test data.
Performance gains are noticeable on all our systems.
We don’t just replace an exhaust — we build an upgrade designed to be installed once and last.
Tips When Fitting
- Professional fitting is recommended for best alignment and long-term results.
• Do not remove your existing system until your new exhaust has arrived and has been checked against your vehicle.
• Always lay the new system next to the existing system to visually compare lengths, hanger positions and pipe routing before cutting anything.
• Ensure the vehicle is level when fitting — not half-raised on one side. Fitting at an angle can cause poor alignment, tailpipe twist, leaks and stress points.
• Loosely assemble all joints first — do not fully tighten clamps until the entire system is lined up, supported and sitting naturally in position.
• Once aligned, tighten clamps from front to back to avoid twist and movement.
• After initial fitting, re-check clamp tightness after a short drive — stainless steel expands and seats itself once heat cycled.
• We ship using third-party couriers, so delivery times can vary — please do not book workshop labour until you physically have the exhaust in your possession.
