New to the forum, just purchased a '17 3IS 350 F sport, looking at quad tips options, seems as if there are only a few options, I read up on the RC axleback fitting the 17 3IS, worth it to purchase a quad RC axleback as to spending 1200+ for a axleback specific to the IS or are interchangeable and fit the same?

 

RC axle back bolts on but does not line up too well with IS diffuser

Apexi makes exhaust for '17+ IS

I'm not entirely sure if this is exactly it but I saw it yesterday and thought it was pretty cool

 

Keep in mind that it didn't line up with a TRD diffuser that's slightly different than the 2017 diffuser:
