cool thanks for the help guys

Even a straight exhaust is not really loud. I have a pipe in my muffler on my duals and is quiet to me. I lost my cat!

well got 4" cat back, and im gunna probably buy the down pipe as well. screw the emissions. Im gunna go no cat/muffler. hows the drone in the cab?? just wonderin

The drone with 4" will barely be noticable, especially with the muffler on.

oh ok thanks tyler. and im cat back with no muffler right now. is it louder with or without the muffler?? i always thought without but some of my buddys say it might be a tad louder with the muffler on.
