About this part
What it does.
The downpipe is the first section after the turbo, and the standard one carries the main catalytic converter and the petrol particulate filter (GPF). Taking them out lets the turbo spool sooner and the engine breathe out more freely.
Removing a catalyst or a GPF changes what the engine sees, so the map is changed with it: we write that on our own rolling road.
In Direnza’s words
- 4″ Diameter to 2x 2.5″
- T304 Stainless Steel
- TIG Welded
- Back Purged
- Replaces restrictive OE catalytic converter
- Improved throttle response
- Faster turbo spool
- Significantly improve engine performance when matched with a remap
For competition and off-road use. Taking out a catalytic converter or a petrol particulate filter on a road car fails the MOT and is against the law in the UK.
Fitted at MMT
We fit it at our workshop in Nottingham and map the car to suit on our own rolling road, with a printout of what it makes before and after.
Questions
About this part.
Is it road legal?
No. Removing a catalytic converter or a GPF on a road car is an MOT failure and against the law in the UK. It is sold for competition and off-road use.
Does the car need a remap with it?
Yes. Without the catalyst the engine sees different readings, so the map is changed to suit. We write it on our own rolling road.
Will it fit my car?
The list on this page is the maker's. If your car is not on it, or you are not sure, send us the reg on WhatsApp and we check before you order.
Can MMT fit it?
Yes. Book the fitting with the part, at our workshop in Nottingham, or collect it and fit it yourself.
