My first chevy

[New2chevy21]

Just bought a 2021 chevy silverado 2500hd duramax diesel with the Allison transmission Feb last year. Loving my first chevy!! What's a good exhaust system to make it sound mean? I'm tired of dodge trucks sounding better than mine.

Straight pipe, and tune out 2 cylinders.

you have already asked this question in another thread. without doing something illegal you aren't going to get the exhaust sound to change.
