better or worse than one with a hi flow cat?

Well, way better at idle and low rpm's. With my exhaust set up it's the most bad a$$ V6 I've ever heard at low rpm's and idle. Past 3,000 it starts sounding bad and then the power realy comes on and it totally changes to a mix between a race car and a lawnmower. The worst part is when shifting gears and the rpms drop suddenly, that sounds horrible. There's also an annoying hum at about 70-75mph that you can bearly heare what the person in the passengers seat is saying, I would really hate to ride in the back seat for 5 hours. You get used to it though, just crank up the radio more.

For power though, it's a really great mod. You won't get near as much top end with a high flow cat and could possibly still have to get an o2 sim to keep away the SES light. If I had it to do over again I would have put a electric cut out before the cat so I can use it at the track and hit the button and use it on the street if I'm far far away from any cops so they couldn't hear me.
