Hi Guys,
I'm looking to get an HMF Swamp Series slip on exhaust. This would be going on a 2017 Outlander XT. Just wanted opinions and experience if it is worth also picking up the fuel optimizer? I wouldn't want any exhaust popping after install but have also seen a few people online say it's really not even needed with a 650 and only a slip on.
Figured I would check in here before purchasing anything though.
