Default Axlebacks require a re tune?

Thinking about a set of loudmouth SLP's and I have a 93 Brenspeed tune...

will I have to get another tune for axlebacks?

no tune required, but it is a requirement here at MF when you install new exhaust components to do a smokey burnout, hard launch, and a screaming flyby. oh and take video and post it up.

No, a tune wouldn't be required or recommended IMO. It's just an axle back so your gains (if any), performance wise, will be minimal. A tune wouldn't change that. But please, do as onederful said

No. Any mods downstream of the O2 sensors don't require a tune.
