I have the dynomax mufflers with a 3rd cat/resonator delete. Getting downpipes eventually. I had my local muffler shop install some adapters on my stock mufflers so I can easily swap between them within 15-20 minutes. Love the sound of my exhaust, lots of compliments, just lots of drone. Great for cruising around town, not for road trips. Like I said though, 15 minutes and it can be super quiet so it's a nice compromise for me.
