Grandprix1 Posted January 20, 2017 Report Share Posted January 20, 2017 Do any of you guys have the ZZP 2.5" Catback exhaust with mufflers? Looking into getting one and want to know peoples opinons. How does it sound? etc. Thanks Grandprix1 Quote Link to comment Share on other sites More sharing options...
Dark Ride Posted January 22, 2017 Report Share Posted January 22, 2017 I'm assuming this is for a 3800 series 2. A lot of people complain of highway drone being pretty bad with aftermarket exhaust. My gtp came with an slp exhaust and the drone isn't bad until I get over 70 mph, at 80 it drowns out the radio unless I turn it up. I can't speak for a zzp cat back although I'd assume it would be similar. A lot of people also say there isn't much power to be gained from a cat back unless you have a lot of other mods.
