Will the sound be a noticable difference with a CATTED DP on a stock catback?

I want the exhaust a little louder, but not too much. I think Catted may be the way to go for me. Im not sure want the smell and increased emissions from my DD....thats what the catless straight pipes are for on my Vette lol, but you cant stand behind that while its idling longer than 2mins without feeling woozy lol. Plus the trouble of switching back to stock for inspections annually....

So imo, if you want just a little bit more tone from your stock exhaust, I would go with the catless hands down. If you are planning to upgrade to a full 3" exhaust at some point then maybe a catted dp would be a better fit.

The problem is personal preference. I've read threads where catless/stock exhaust is good, barely any louder...some say it's a lot louder but not overbearing. *shrugs*
Different people say it's loud while others went catted 'coz it was too loud. hell some have catless/MD and think it's not too loud. Best case scenario would be to hear it in person.
Edit: try this..AFAIK this is a zzp catless dp/stock catback. I like the sound but it's too loud for around here 'coz the cops are dicks, as i have found out recently in my cavy. https://www.cobaltss.net/forums/pictures-videos-64/tc-zzp-catless-vids-189718/

Instead of filling the top up with stickys, there should be a thread that links to other useful threads. Sort of a universal FAQ.
There's a ton of useful stuff on this site that just takes a bit of searching. A FAQ would bring it all together nicely.

The smell is definitely there however it is not overwhelming I am actually use to it now and don't notice it any more. And no it does not get into the car that's how exhaust systems are designed, otherwise people would be dying in rush hour.

Reason I ask is because my wife and I like to drive my car together on the weekends and I want to make sure that it's not going to be affecting my little girl. I guess I'm just use to my true duals on my old 01 SS Camaro (big motor, big cam, no cats = wayyy stinky).

Concerning carted dp's.. I just got one with a spun metal cat from ZZP. My MAF is messed up but after that is fixed I will see about getting some sound clips of it. Those saying there's no sound change are crazy. There DEFINITELY is. At idle and normal acceleration, no, but put a load on the engine and its undoubtedly louder.

Just FYI Cold Start up is not a very good representation of what the catless downpipe sounds like as when the car first turns on it goes into Cat Warm Up Mode which is loud as hell for 30-60sec and then the sounds calms down alot.
It would be great to have a vid of a car with a catted DP

I really like it. Cold start up is not TOO much louder than stock exhaust. It's a little louder. Warm idle and just putting around town I can't even notice a difference in sound. If I give it a little though, say... 25% throttle or more it's very noticeable with a window down. It's quite a bit louder then. Inside with the windows up, I can hear a pretty nice growl.
It's perfect for me. The only reason I didn't go catless was I was afraid it would be too loud and any louder than my catted would probably be too loud for my taste. So I'm very happy with the results. Oh I get my car back tomorrow morning. (Saturday) Had a broken wire/pin connection in the plug for the MAF.
