How would you rate the fit/finish/quality of this setup?

After doing a lot of research I think the Q4/Powerbomb seems to be the best way to go for quiet power, without costing a fortune.

I'd like to give it a try on my '07 YZ450F. The stock exhaust is obnoxious by the end of the day, or at the end of a long race.

Man I agree with the obnoxious sound after riding. So I decided to do something about that little whisper/hiss. Drew a pencil line arount the outer section to eliminate that curl in the turndown...Dremel...and now she sounds good. Can totally tell it flows better and dang sure sounds more like a thumper now just not so loud like a straight through...
