You can look up other brands of the same exhaust. They are all clones. I think some are DNA motoring, Spec-D, Beluga Racing and a bunch of others.
I spoke to a local shop in my area that was selling the exhaust and asked them their opinion on it. I was told it is an "okay" exhaust in terms of if you want an exhaust upgrade on a budget. Fitment will only get to 95%-ish in terms of perfect alignment.
I see you're out in Vancouver, so you might not have an issue, but the shop told me one of their customers ran the Rev9 exhaust all winter here in the Toronto area without washing their car once
and the pipes had rusted through. I guess the quality of the stainless in these systems is a hit or miss.
