When I worked for a race team, we ran vortex systems and found a whopping 12bhp extra using these on a fiesta st! We did before and after RR back to back on the same day to prove!
I can't guarantee all what they say, but they did work for us!

Which race team did you work for?
i'm in quite close with silver fox racing who are about to make a comeback to st's after a year doing clio cup, and also meridian motorsport, who'll be running something special this year
The guy on the phone said they work on standard cars. I.e cars with cats etc still on.
So if you have an exhaust system with decat then im not sure how this can improve it? Because all its doing is releasing back pressure?
