I am considering the SLP Loudmouth Axleback for my 05 GT. Does it drone at any time inside of the cabin? If so at what RPM range? What is required on the install? I am wondering that if I don't like it, how hard is it to go back to the stock setup.
It took me 3 hours but i was putting the brackets on wrong. I figured it out finally and i seriously couldn't be happier, sounds awesome, not to loud though. good stuff. Going back to stock would prolly take 30 min. not bad at all to go back.
45mins or so to put on, probably could 'undo' in less time... they definitely are louder, I LOVE 'em, but you CAN hear them inside the cabin when the music is not on, at most all rpm levels if you are accelerating.
Steady speed/rpm not so easily noticed.
I love my SLPs! One of the best buys I've made. Some say you can have the same results with generic tips, but I think I'll stick with the bolt on SLPs and be happy with it.. No regrets at all..
