Exhaust loudness rating

[GigaHz]

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.

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.

The Borla Atak is the loudest Ive heard on a mustang that doest have long tubes. As a matter of fact, my 2015 with the Atak's is louder when you get on it than my friends 2014 with long tubes and straight pipes after his x-pipe.

I haven't heard any other 15 GT but mine. So hard to say. I have the MBRP street and its not that loud. I would give it a 5 out of 10. i think this is perfect for DD and no drone. I have a baby coming in a few months and this will work perfect.

Yeah I think we can all agree atak is the loudest haha

I would say corsa would be up there. Haven't heard any other in person to really tell.

Outlaws seem pretty damn loud especially the ABs

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.

BTW - per both CJPP and Lethal Performance, the Roush axle back + H-pipe resonator delete appears to be a very, very loud combination.

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

I think the ford touring axle back will be pretty quiet.

I've got the S-Type Catback and it is loud. Very much in fact. Now, I'm coming from a VW family so I'm used to a certain volume. I love the S-Type system, but wow is it ever loud.

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.

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.

My Corsa catback is loud as shit, but it's nice and clear too. It's so loud that I might not do long tubes... and if I do they're going to need to be catted.
