MTC Motorsport – Audi S4 S5 Downpipe with 200 Cell Hi-Flow Sports Cat & Heat Shield B9 3.0 TFSI
The S4 downpipe is machined from T-304 high-grade stainless steel and is tig welded in house.
Our downpipe comes straight from the turbo providing a sharper throttle response due to a faster spool of the turbo.
It will provide noticeable power gains and a much more aggressive exhaust note which sounds amazing.
It produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger.
The cylinder charge is increased which gives you maximum performance.
Finished in brushed stainless (with heat shield)
These will fit the following models:
- Audi S4 B9
- Audi S5 B9
We have tested this product and found increases of around 20-25 bhp without tuning and 120bhp+ on a tuned car.
Professional installation is recommended as some exhausts sit slightly different from others and can be tight.
If you have a later model car with OPF/PPF filters they will need coding out so you will need to find a tuning company who can do this.
These should pass an MOT emissions test when fitted. They are road legal and Euro 5 rated.
This product comes with a lifetime warranty.
