This modification is not actually technically legal in Texas it will be considered an exhaust leak and you have do have a "muffler" most state inspectors (like myself) will look the other way tho, instead I recommend if possible just loosen the 2 bolts where your exhaust pipes meet (from your midpipe to your muffler pipe or your y pipe to your midpipe) and put a nut in between the 2 pipes on the studs then close them back up as you would normally thus leaving a gap about 1cm this will allow alot of sound through and will only cost at most $5 for the nuts and will only take up to 15 minutes, no power tools needed, can be done in a driveway, and can quickly be undone when inspection time rolls around
