How much and where to cut exhaust?

I wan't to do something similar to a cut-out but more permanent, and free. I was thinking about just cutting out a piece of the exhaust. I was curious if you guys had any ideas on where to place it, and how long of a section i should remove. I want my car to be loud, I already have a 3in straight pipe in place of the cat. I was thinking somewhere past where the cat used to be, so I don't have exhaust fumes pouring out by the door or something. I was thinking maybe a 2in x 10in section, but thats just an example. I just made a rather large CAI, and figured i might as well free up some exhaust while I'm at it. Oh, and if someone has done this, and it sounded like shiiit, let me know....Thanks,

That might end up sounding like sh*t, but I don't really know. Have you thought about possibly just adding a bullet muffler and a turn down before the axle? Just an idea.

Yeah, actually I was considering playing around with how a cherry bomb sounded with a turn down...but I think I'll throw the car on the lift sometime this week, or next, and just take a look-see. If i cut out a chunck and it sounds trashy, I'll weld it back in and come up with something else...

I used to just unbolt the muffler on my hooker catback. It was louder and more obnoxious than Rosanne singing the national anthem(years ago buddy). but hey it worked...but now i have a cut out cause It kinda hurt having a muffler and tailpipes repeatedly landing on my chest

I had full stock exhaust and it was too quiet, so I decided to go a cheap route for now until I get my long tubes. Since their was no brackets holding up the pipe right before the axel and their wasn't really enough room for a turndown aka dump, I decided to cut the pipe right after it runs over the axel. I then removed the muffler, 30 lbs which is equal to about 3hp. It is VERY loud, but doesn't sound all that bad. I always have people ask me what type of exhaust I have and I just say "stock...minus the muffler" Hope this helps.
