Todd,I have the Roush AB's and they have some good loudness to them. I am certain they are older than some of the full catbacks that are made.

I think the ford touring axle back will be pretty quiet.So can anybody rate all the after market exhaust from quiet to loud. I am guessing the axel backs are the quietest? I am looking for some thing just over the the stock volume.
Absolutely! The Corsa Xtreme is LOUD. Much louder than I expected based on the videos. I would venture to guess that the Borla ATAK is the loudest followed closely by the Corsa Xtreme.Has anyone heard both the Borla ATAK and Corsa Xtreme in person? It seems nearly impossible to gauge/compare volume levels based on video clips alone.
Installed the Roush axle back on my otherwise stock Performance Package GT (3.73 gear), and also agree that they are quieter than stock at average highway speeds (55-70mph). They are much louder than stock at start-up, have a DEEP (and arguably quieter than stock with windows up) rumble at idle, are louder than stock at sustained speeds above 70mph, and absolutely howl under hard acceleration at any speed. Overall, I'm "mostly" satisfied after a couple days around town and a 150 mile road trip, but do wish the idle volume was louder.Todd,
Surprisingly my Roush Axlebacks got quieter while cruising honestly they might be even quieter than the stock exhaust! They are still aggressive and loud under heavy acceleration but damn quiet on the highway! Just got back from a 400 mile round trip and i can say that this is the exhaust to go! By the way i averaged 25.5 mpg on 91 octane fuel cruise set to 71 mph![]()
