roush axleback

Looking for any help. I have a 2016 Mustang V6 and just had my Roush Axle backs and a flowmaster x pipe installed at a shop. I had a second mechanic verify that the bolt ons are tight, but I’m getting a weird rattling sound/vibration on cold starts/idling and driving at low speeds. I have some...

I know the mishimoto pro axlebacks have been spoken about a bit for the Mustang GT 15/16/17. But does anyone have an idea of volume of them with a stock resonator? The manufacturer said they do not have decibel readings for them. Does anyone have this set up, with a descriptive idea of sound...

Hi everyone, I have ordered a Roush axle-back exhaust from a Roush dealer. I have zero knowledge in axle-back exhaust until I have watched more videos to find out how loud that is... However, most of the videos are all for the ecoboost from 2015-2017 V6 engines, and my car is the 2018+ I4...

Looking to buy a used set of Roush axle backs that fit a 2015-2017 GT. Can be dual tips or quad tips. Almost any condition will be considered as long as it is priced accordingly. I will be likely welding a set of quad tips on to fit a GT350 valence. Please provide photo if possible as well...

Near new Roush axle back, only 100 miles on it. Like new condition. Didn't like the sound so replaced with borla touring cat back. Pick up in Southern California (San Clemente) $400 cash

i am looking into the roush axlebacks and have read many different things. I have a few questions for those who have it installed on their v6. Does it drone? if so how much & what rpm? Does is ever get too loud/raspy? crackling? Do you love/hate them? Would you recommend? Prefer any other...
