hey you guys a question about exhaust do you guys perfer to have your cats in or out?? thank you

 

In most areas, it is against the law to remove the cats. If you have emissions testing in your area, the cats are a must.

 

i understand that but which one sounds better?? i dont have cats in mine but im putting some in today and im just trying to see if its the right choice because i had a copcome up to me and say my car was to loud
