• The RS4 downpipes are machined from T-304 high-grade stainless steel and are tig welded in house.
• Our downpipes come straight from the turbo providing a sharper throttle response due to a faster spool of the turbo.
• They will provide noticeable power gains and a much more aggressive exhaust note which sounds amazing.
• They produce 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

These will fit the following models:

We have tested this product and found increases of around 40-45bhp without tuning and 140bhp+ 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.
