Long tubes catless mids for dd?

I was looking to put longtubes with catless mids stock catback on my car which I dd I want a nice sounds but nothing crazy. I feel like it might be too loud and get annoying after a while. What's some of your opinions should I go with catted mids and stock catback?

On a stock catback, longtubes with catless mids will be very mild.

Catless is fine if you don't mind the extra smellyness

I had Kooks LT's with the uncatted mids and the stock 04 catback on for about 2 weeks. Wayyyy to quiet and despite what everyone else says I thought the car sounded weak and just awful. Went with exhaust from the mids back and I DD 50 miles a day no problem with the set up.

I have pacesetter lt's and catless mids with stock catback. Not much louder at idle in my opinion, and you can't really tell a difference from stock at highway speeds. But you can really tell at wot, car sounds like it should have stock. I expected it to be a little louder honestly.

Depends on your budget and what you use the car for. If you daily drive, I would go with catted mids. Nothing worse than smelling like exhaust all day at work, or on a date. Power difference is insignificant between the two. Catted is a bit quieter, but again that's not such a bad thing. I outgrew getting attention from the police a long time ago, so having the loudest exhaust does not appeal to me.

I'm not in a hurry to put all this on so I can save up to put a catted mids. That's what most I don't want having the extra attention. I have a trans am with cam lt's and true duals dump so I'm pass the loud exhaust thing. Just want something that sounds nice and not annoying.

IMHO catted cars are the ones that stink. They smell like rotten eggs. FWIW I run LTs with just a X pipe and Borla Pro XS muffs and it has a very nice sound compared to a lot of goats that have cats and louder mufflers.

I don't find my cat-less cars to stink at all. I like the smell but I also like burnt toast so my opinion is irrelevant

I don't smell like gas at all with my catless setup..I don't know what's wrong with your cars. These GTO's smell a lot less than my old 04 GT and 03 Mach 1 did with catless setups.

On stock 04 catback it's not loud.

I was worried about the smell but went catless anyway and in my case rarely smell anything. Your stock exhaust should sound good catless.

My 06 has pacesetter LT's with catless mids going to a stolenfox H pipe and stock exhaust, and my car is pretty loud. But, I like loud.

In fact, the first thing anybody says about my car is "wow, that's loud". It also stinks. BUT, I am pretty sure I am running pig rich down low and need to get my tune cleaned up.

The smell shouldn't be an issue, especially if you lean it out with a tune. I cant wait to go catless...

My car = DD + catless mids + Kooks headers.

VERY mild around town. It sounds pretty much stock under 3000RPM as long as I don't goose it. Once I hit 3500RPM, though, those headers start a-singin'. WOT throttle is just a wicked sound, makes me pitch a tent.

It was a little louder than I had expected, but I've gotten use to it and my neighbors say it's not as bad as their cars (70's chevy truck, and 68 camaro ss).

Older cars seem to have alot deeper of a tone that you can hear better (like inside a house)
At least my car sounds more high pitched being stock manifolds x-pipe and some bullet mufflers compared to say a 67 427 with sidepipes

I did catless Mids with shorties and stock catback. I like the sound, not too loud, but deeper than stock. I'm not too sure about the smell, I always have a window down and never smell like exhaust.

I guess this is what I was looking for. Thanks everyone.

I've got pacesetter LT's and catless mids mated to a custom catback with Spintech mufflers. She sounds very nice, IMO. The idle isn't deafening, but you'll certainly know the car is running, lol. At WOT, she screams her blessed little heart out. With my setup, I deal with very little drone (if at all) and if I feel I need to be as quite as possible, I just drop the RPMs to idle and that usually quiets her down enough to only wake up only the stingiest of neighbors at 2 AM. Honestly, if you're looking for tone over volume, I'd focus on your catback more than headers and mids. Yes, they obvious play a factor in everything, but by adding headers and catless mids to mine, all it did was make her significantly louder. The tone and note stayed pretty much the same.

Ive had my Lts and Catless mids on my cars for about 40k ......... 15k of that was with the stock catback. I personally thought that was too quiet, so i went to dynomax bullets and a jegs x-pipe and i really liked the sound.

I haven't had Cats on the GTO or my Last Camaro, I love the smell and think my DD is weird cause I can't smell it, but a Mini without cats would be strange haha

I'm starting to not notice the smell as much on my catless mids. Can't wait to put on my Afterburners tomorrow for a better sound.

Gonna be loud! I have the Afterburners but I'll be adding a Magnaflow Tru-X muffler when the headers and catless pipes go on.

Magnaflows have a good tone to them while still being relatively neighbor-friendly. The thing about exhaust is you may need to mix and match a few times before you finally find what you want. I got lucky and got it right the first time, lol.

I ran kooks 1-3/4 and catless mids about 20k miles (1year) with stock cat back and cammed.

Then for a month and half I ran it with moroso spiral flow race mufflers. Stock car back was too quiet.

I sold it all and back to stock with the moroso's, due to money reasons.

I never noticed the smell, but I'm used to cammed no cats carbed vehicles. So it didnt bother me.

If you think it'll be too loud don't do it.

Sound is subjective. I hate flowmasters, but others love them. So everyone's opinion with a grain of salt.
