I have the borla atack and love the sound and look of the system. It was a little loud inside the cabin (no drone,just loud) but after I dyno matted the rear hatc area it was perfect for I have upgraded the sound system also and I wanted to enjoy that
I have the borla atack on my 26 performance. It definitely wakes the car up . The only problem I had is that there was a lot of cabin noise so I dyno matted the rear hatch and it toned it down quit nicely. I have aftermarket speakers amp etc and I like to hear the stereo.
Ams intakes tune etc...
