i have a custom powerflow system on my 2.0ts an its alright, just alright tbh.
i did like the fact that i was able to get a tip that looks exactly like the standard lusso one but just marginally larger bore, also i was able to customise mine by specifying
-must be mandrel bent (this is not standard on powerflow but is on ragga etc)
-no larger than 3" as i need decent backpressure at low revs to clear the manifold with a decent vaccum effect.
-i had an extra mini muffler added as i thought they were a bit noisy rather than 'tuned' sounding (sounds sweet as a nut now).
all in all i ended up with a very decent system and im happy with it, power delivery is a bit different from standard, it seems a bit more torquey at low rpm, and the surge i had @4300 when the variator changes the valve timing isnt as apparent now but the power is definitely felt shortly after.
it sounds civil enough at low revs and when its at about 6000rpm it hits a note that is unmistakable and coincides almost exactly with peak power which is handy to mark where you want the engine running when your givin it a bit of welly
as is with most things you get what you pay for, its not quite ragga but its close enough that for my money it was perfect, i would compare exhaust choice with filter choice; the BMC CDA, its the best of the best but halfrauds do a copy for £60, an unless your intending to race your car its not worth goin for the all out super delux version when youll never notice the difference.
suspension tho id pay for the best i could possibly afford!
