I managed to get the drivers side installed and the passenger side loosened before I decided to call it an evening. I installed my 12s SW long tubes the same way and I'll admit this install has been considerably easier than the 12. Even being on the jack stands I have more than enough room...
The sport axle back(extreme catback muffler) will be louder than the sport catback. If you pair the touring axle back (sport catbacks muffler) you should be at roughly the same volume if you still have the cats on he car.
I am a MAC. Been in 13.5 years now.
I have I be out there at 8 or so to set up and coming from the OKC mustang border. So I'll be leaving my place around 730. Fort thunder is right next to the warren theater off of I35 in Moore.
