Recommended: professional fitting
Exhaust installation needs a lift and a range of tools. Incorrect fitting can cause fault codes, loss of performance or even a fire risk.

Hot sound, cold work.
This page covers the general installation of exhaust systems (downpipes and cat-backs). The product-specific installation steps are in the description on each product page. Professional fitting is strongly recommended. Whenever you get stuck, ask us on WhatsApp.

If you want to try it yourself
Cat-backs and rear silencers can be fitted with a lift and basic hands-on skills. For downpipes, we especially recommend professional installation.
Steps
The five-step general flow.
Every product installs differently. Your part's installation steps are in the description on its product page; this page covers the basics.
- 01
Let the car cool
An exhaust runs at hundreds of degrees. Let the car rest at least 2-3 hours before installation; the manifold, downpipe and pipes should be close to room temperature. Touching a hot exhaust causes serious burns.
- 02
Remove the old system
On the lift, start at the hangers and undo the bolts from front to back. Unplug the lambda (oxygen) sensor connectors carefully without straining the harness.
- 03
Check gaskets and hardware
Use new gaskets. Replace rusted bolts. A little copper paste on the lambda sensor thread makes future removal easier.
- 04
Fit the new system
Connect everything loosely first and check alignment. Then tighten the bolts front → back to the manufacturer's torque values. Pre-loading the hangers leads to wear and can let the exhaust drop later.
- 05
Warm-up + final check
Start the engine and let the exhaust warm up for 10 minutes at idle. Check for leak noise, smell or vibration. Re-check the hangers and flanges after the first 100 km.
Tool list
The exhaust installation kit.
- Lift, or a jack + axle stands with enough clearance
- Torque wrench (10-80 Nm) + socket set (8-17 mm) + extensions + ratchet
- Lambda sensor socket (22 mm)
- Copper paste / high-temperature grease
- WD-40 or similar (for rusted bolts)
- New gaskets (don't reuse the old ones)
Critical warnings
The three most common exhaust installation mistakes. Knowing in advance is cheaper than replacing afterwards.
- Caution
Touching a hot exhaust
Never touch the system within 2-3 hours of running the car. Exhausts exceed 700 °C; touching them before they cool causes serious burns.
- Caution
Lambda sensor damage
Forcing the sensor out, or removing it without unplugging the connector first, triggers fault codes and reduces engine performance. Use the sensor socket and pull straight.
- Caution
Over-tightening
Over-tightening flange and hanger bolts can tear the gasket or crack the flange. Always use a torque wrench at the manufacturer's value.
