well im alittle confused so i will attempt this at the best of my ability.

the cut outs will yield more hp, a figure i dont have for you.

doesnt the goat have true duals?

My 04 has two COMPLETELY SEPERATE pipes fom headers back... idk how you would run a catback off true duals... not to mention there is only one cutout in the rear bumper.

weight reduction, I'd say 30-35lbs less in metal with the cutouts. much louder exhaust system and less restrictive... in terms of hp gains vs catback, not much. a few hp...

the bad news, if you decide to lower your car, the cutouts will start scraping a lot...

Well, I have the magna flo catback & cutouts off the headers before the Y pipe. The magna flows very well. I run the same times with or without the cut outs... I prefer the open exhaust just for the noise !!!

yeah i think im gonna stick with the cutouts.. i just cant stand the interior noise and vibration sometime...and midpower acceleration sounds like poop in my opinion...but down low it sounds way better than a catback...and up top its not bad....yeah mines actually lowered,lol...
