Nice Rumble

Really easy swap out, super straightforward and really quick. Came with everything you need (Gaskets included) Has a nice subtle burble, not terribly loud or obnoxious, looks good as well!

Sounds good not too loud tasteful the left pipe had to be bent down a little but other than that went in in the matter of 20 minutes


Thank you for the 5 Star Review! FactionFab makes great exhaust components! Sometimes loosening the flanges after installing into the hangers can help with adjustment! Rumble On!
