Hi guys, not been on here for a while as I've been pondering over my car and what to do with it, I have an e46 2001 325ti compact (which I quite like) but looking for more power, yes I know I've read the threads on various forums about chasing horsepower in N/A cars, some here will remember my enquiry regarding 330i engine swaps and the general opinion was yes a decent amount of extra power for minimal outlay as apparently all the ancillaries are the same etc, but apparently not, I believe the throttle bodies are a bigger bore, 68mm to the 325's 64mm, so I assume the intake pipes would be bigger and the air flow sensor, plus I thought about the implications of insurance, so to cut a long story short and a lot of research, I have decided to keep my little hatch and engine, which I like and for minimal outlay squeeze a few extra horses out of it, (sometimes its better the devil you know), so the question is, after browsing one day I stumbled on a site called Vortex Exhausts, to read it and take it at face value it sounds like a revolutionary idea and great upgrade for any car is I believe the guy who thought of it done for exhausts what Dyson done for vacuum cleaners. Basically a section of the exhaust spins the gasses, which DRAWS them out resulting in MINIMUM 10% extra BHP, torque and fuel economy, Has anyone here any knowledge or experience with one of these? Yes they are 800 quid for cat back, but then you'd pay around £550+ for say a longlife stainless system which doesn't boast any extra performance or economy of any real relevance, you are just paying for an exhaust that lasts longer and perhaps sounds better, They do claim the figures could be much better, but playing it on the conservative side so not to disappoint customers, so why hasn't every boy racer, petrol head or enthusiast heard of them??
I've drawn a blank with the engine swap thing as I can't be 100% sure about everything as I'm getting different feedback from different people, with regards the vortex thing I think how it works is that it builds it's own momentum as it spins, it works with dysons, we use the same technology in our steam boilers at work now as it's more efficient, so there must be something in it, any one know anybody who has one?
Actually no I haven't, that would be interesting, I must admit all I'm going by bis their explication and the explication from ed China as he used one on Wheeler Dealers and thought it was great and in suppose I saw the logic in how the system worked but still needed other opinions too, Ok point taken, thanks guys, what does the disclaimer say any way?

If it was this simple, why isn't it fitted by car manufacturers already? Why hasn't the company sold the idea to a big car manufacturer? If you came up with a way to improve fuel consumption by even 1%, a big car manufacturer would pay you ten figures for it, yet here they are, selling to the gullible.
Just another BS "fuel saving" device that belongs in the same bin as magnets, fuel catalysts and high energy spark plugs.
of course that did cross my mind even my missus mentioned that, but like I said there are other applications where spinning gasses or air does work so seamed a bit plausible, that's why I came on here for opinions first as I wasn't completely suckered into itJust another BS "fuel saving" device that belongs in the same bin as magnets, fuel catalysts and high energy spark plugs.
