MTC Motorsport Astra VXR/GSI Z20LET 2.5″ Stainless Steel Decat Downpipe

The Astra VXR downpipe is machined in the UK from T-304 high grade stainless steel
Tig-welded in house to deliver the best quality
Our downpipe has been engineered to fit all cars with a Z20LET/Z20LEH engine
2.5″ diameter which is more than enough to flow 290-300 BHP
Mirror polished finish

It will fit the following vehicles:

Astra VXR 2.0L Turbo 16v 2005 +
Astra MK5 SRI Turbo 2005 +
Zafira VXR Turbo 2002 +
Astra MK4 GSI Turbo 2002 +
Zafira GSI Turbo 2002 +

The downpipe will provide a sharper throttle response, making your car feel a lot more free and responsive. We have tested this product and found increases of between 12-15 BHP on test vehicles.
The decat is mendrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
It will come with the gasket for the middle section and the bolts needed to install it.
Professional installation is recommended as some exhausts sit slightly different to others and can be tight.
We recommend purchasing a 304 stainless steel Lambda sensor spacers to prevent the engine light coming on in most cases. If you search our other items you will find these.
