Morning all, I am wanting to put a 40 series flowmaster on my 2015 Silverado 1500. I am wanting to dump the exhaust over the rear axle, when doing so I am cutting off my catalytic converter. If I cut it off, will it throw codes in whack on the computer? Any help is appreciated thanks.

 

That's not a converter at the axle, so cuttin it off won't be a problem. Have at it

 

What he said. Also, Flowmaster will sound aggressive and loud yet others experienced some drone.
