Hi there, here is what I have. I got a borla sido cat back with an electric cut out and hi flow cats, my personal thought is that the truck even with the cutout open with my setup is still quiet at idle. But then again I'm just a young dumb 20 year old punk. However she roars under load. If I where you I would go to summit racing and by a cutout and electric controller and install that. Because I like to talk to the people in the truck when I'm riding with them. Any throttle and you can't hear when straight piped. Plus I noticed when driving with the cutout open milage goes to crap and trust me I hardly go to wot when the cutout is open cuz it is LOUD!
Where I live (a nicer suburb of cleveland, ohio) people look at me like I don't belong with my loud monstrosity so I like to beable to quiet the noise.
