cats or no cats...debate

Dfw lt's even more now lol. I think it'll just be a in the moment decision weather I want true duals or single. Depends how much more moneys the duals are. Should I wait to cut the cats for when I do headers or it really doesn't make a shit difference? Just don't want a hack job of an exhaust with exhaust leaks.

How obnoxious is the sound without the cats when going down the highway? I want to buy some llp's for my nnbs but a lot of the driving I do in my truck is highway. Jared's clips seemed really quiet when cruising, but he was also probably going 15-20 mph so I am not sure how much of a difference going 75 would make.
 
its not too bad just depends on what your rpms are at at that speed and gears are the culprit for that i have 3.23s and mines pretty quiet on the highway even with the cutout open it stays under or at 2k rpms for the most part
 
I have personally had a guage on a NBS Suburban with a 5.3(checking for a bad cat, ended up being the pump losing pressure underload) and the gauge read 0 the entire time except when you would snap the throttle fast and it only came up to .5-1 PSI long enough for the needle to come up and drop back down, just like vacuum drops and comes back when you snap the throttle. That sold me to not get rid of the cats until I do headers and that for cost reasons only because I am a cheap ass.
 
Guess it'll all ball down to price then if I keep the cats or not. I think the reason the cats on the fords suck is bc they have 4 of them lol most guys do the "rear cat delete mod"

One video I was doing 60+. The other was 50+ Speed limit is 60 and 65 on the highway, the video where I pull into my house started off at 50mph then cruising in the hood at 20mph

The bottom vid I rolled the windows up at like :30

this is also on a dumped application, if it weren't dumped it would not be as loud. It won't make a huge difference, but there is a difference when you route it out to the rear. I had it ran to my bumper before dumping, the drone was pretty much non-existent then.

Mine is infront of rear pass tire and it drones sonewhat but isn't that bad... now when I had turn downs with me being so low it was crazy loud but sounded so sweet. Drone would kill your ears at 60+ though...
