Suggestions between two exhaust

I know they're a lot of exhaust post but I'm stuck between two axle backs which are the Slp Loudmouth Axle back exhaust and the Roush Axle back exhaust.

Any suggestions or info on each exhaust are appreciated.

Without doing any research I would assume the roush exhaust is rather tame compared to the SLP. Are you trying to decide wether you want to shred ears all the time or just WOT lol

Do you have any other exhaust mods or are you planning at any point to remove the cats or resonators?

Roush if you are planning never to change anything else, resonators, cats, longtubes ect. If you are changing anything else Borla s-type. I had Roush for 30k miles and after I removed the resonators it didn't sound anywhere near as good. Loud but not as good.

Roush sounds good with stock exhaust, I personally think it sounds good if you change other parts of the exhaust but with that being said it get's very loud. I have a high flow catted h pipe with Roush axle backs and I went high flow instead of O/R trying to keep the rasp down, although I like the way it sounds, it may start to get on my neighbors nerves lol so I may switch my axle back to something deeper and throatier but I'm not sure yet. Although the SLPs aren't necessarily quiet either, I had Pype bombs and they were every bit as loud if not louder than my Roush and SLP and Pypes are both essentially just muffler deletes.

I had the Roush AB on my 14 with the rest of the exhaust stock and while it sounded very good, it got to be too loud over time for me. I switched this out for the GT500's with resonator delete and now it sounds perfect.
