Ive heard the vortex system is just a gimmick. .I believe the power gains are becasue your replacing a cat or muffler with a box with fins in it that is less restrictive. your probably better off running a straight through pipe as it will provide the same or similar noise reduction better power gains and be just a touch louder. Im just guesing though. id like to try one though to see for myself
yea thinkin about tryin one ive had a quote for 365 quid inc vat just for the race flo system it replaces the mid pipe between muffler and cat not the cat itself. I spoke to the guy this morning and reckons a gain in power and torque of around 10%. might do a rolling road before and after then see once and for all what difference it makes. bit of a dear test tho lol
