I've heard this exhaust system in sydjaz's car, as both a passenger and driver before he sold it. Quick blast around the fishmarkets, Western diistributor and overpasses/tunnels.
It's got a nice note, with a fair bit of character and burble at idle and at WOT, it's quite aggressive. Definitely not a Milo tin exhaust attached to a Hyundai Excel.
From memory, he had it fitted without resonators though which produced a bit of drone around 2800 rpm. I think having the resonators would remove that.
I can vouch that the exhaust would be near new.
