Default Slip-ons

Looking for slip on exhaust advice, on a stock 2012 LTD, after cat removal & open AC. Anybody using S&S Grand Nationals? What was the HP gain? Are they quieter than most?

Wow, two days and nobody jumping on your thread to tell you how much they like every kind of slip-on BESIDES the one you asked about? What is this world coming to?

Good luck. I don’t know anything about that particular muffler either.

Your askin about a specific slip on. Had he asled about any pipe that makea good power there would be replies..if all your adding is a slip on power isn't really a concern worry about something else..when you get them make sure to get it dynoed and tunes and post the gains so the next person knows the answer to the exact same question

Welcome from West Michigan. Wish I could help you out about the Grand Nationals. The combo of the intake , exhaust and tune will help out but some time on a dyno will be more precise. Even better if you knew what HP you started out with.
