Im trying to figure out a light weight but still good sounding / not too obnoxious exhaust that is light weight. I currently have bbk y pipe into a cutout into a borla cat back. I was going to take the cat back off and save 40-50 pounds and just run no exhaust, but I don't want to be super loud at night. I only drive once or twice a week so I may just run no exhaust.

Any opinions ?
