I did try them one time and they were LOUD beyond belief on mine under WOT (Wide-Open-Throttle).
There was simply no-way I could run them in the area I live in.
Especially if I was going to run mine at all through the gears even Semi-Aggressively.
But your question was what did I like and what would I run ?????????????
I loved the overall sound of the Borla (Magnapacks).
Now those with my Power level are so Awesome sounding at idle or under Power.
I ran those for years when my Bullitt had the stock 5-speed manual transmission in it from Ford.
I could get around the Dreaded Drone inside the Cabin by running mine in 3rd gear with the Ford-Racing 4:10 gears at slow speeds.
(Like in neighbor hoods etc)
I decided to get rid of them when the decision was made to have BRENSPEED convert my Stock 5-speed transmission to the TCI SSF (Super Street Fighter) 5-speed automatic 5R55s.
I new if I was lugging it in the Higher Gears with the automatic it would simply be UN-Bearable inside the cabin.
The only way around that would have been to have manually shift the TCI and I decided what was the point in having the automatic if I was going to constantly having to manually shift it.
So, sold the Borla (Magnapack) axle-backs and switched to the current Borla (Touring) complete stainless exhaust system.
I have now been running what it has for years and as I have gotten even older I am now enjoying the Borla (Touring) system even more.
