You'll also definitely pick up some rear wheel horsepower with it open over your Flowmaster 80-series crossflow muffler...Most people do. But again, I just can't get over how much louder the cutout is as compared to the Flowmaster American Thunder system I have on the car. And I absolutely love the incredibly mean/raw tone of it (cutout) w/ my MAC headers + highflow cat.
BEST $35.00 I've ever spent, LOL.

I picked up 6hp and 3lbs with the cutout and I think it sounds better than alot of catbacks I've heard. I had it installed right before the axle and with it open it caused a little knock retard on the dyno but since I got the Lt4 km and headers I need to head back to the dyno and see how much it will really give me.

Re: cut out's
IMO an open cut-out is way too loud for the street and will vibrate the sh*t out of your interior. I only open mine at the track. My local exhaust shop fabbed up one right in their shop; no need to buy one and take it to them. The more HP you make, the more the cut-out will will add to your gains. I dyno'd with and without the cut-out open, picked up 15 HP.

Borla completely open vs a cutout? Is there a difference?

After having a $35 cutout installed on my LT1, I would never even consider purchasing a new Borla system for $600+ when the cutout gives the same gains (and sounds better/meaner to me). And like a Borla adjustable system, you can simply cap up your cutout anytime you want to run the exhaust through your muffler instead...

Re: cut out's
I had an electric cutout on mine, with the 80 flow, and I also gained about 10hp on the dyno before I did headers. and Yeah it's loud as crack.
revving sound like a Nascar.
I capped my cutout and removed the 80 and had a 40 series race muffler custom run, and it's almost to loud with just that, I did say almost.
