Here you go buddy, maybe you can get some ideas from here: www.ls1sounds.com. I finally found what I like by go with a 3" cutout.

Install a crossover pipe and a helmholtz chamber near the muffler on each side. These will greatly reduce the exhaust noise.

Typically 26 inches long and the same diameter as your exhaust piping will kill noise around 2k rpm.
Pm me your email and I can send you a spreadsheet that lays out the math on this if interested.
