Default Which muffler for true duals? (opinion and Idea thread)

Ok so I recently went the tru dual route and as much as I love the new setup It did lose one thing. I no longer have that Chest thumping pop that I once did. I think thats just simply due to the larger pipe and having the muffler right at the end of the exhaust but I now want to put two bullets right off the headers and then dump before the axle like it is now. I just want to get opinions as to what all sort of bullets are out there. I know about the kooks, dynomax, borla, and SLP already but feel free to give opinions on them. I have a heavy oval track background and I have thought about race mufflers just to take that edge off that you get with open pipe but still have the hard hitting idle and screamer up top. Let me know any ideas!
Thanks in advance

Flowmaster super 10s sound good, tsp bullets, I opted for tsp sweet thunders and it sounds fking great. If I were ever to switch....I'd definetly get the super 10s, very agressive "race" sound. Couple of my friends with stangs have them and they sound really good.

You do not list what duals setup you went with for one. Another, losing that "pop" is the whole reason most people move to duals over an ORY -> Catback setup. And no matter the reason, that pop was never chest thumping unless you have an issue with your car.

Im not really following where youre going with that but my duals are completely custom. 3in all the way back with an x after the trans and two flowmaster 4x9s under the rear seats. I am just trying to get back some of the loudness at idle I used to have. Right now the rumble is insane and shakes the windows of my house but it just sounds like thunder. I want to get some of the open pipe sound back. I feel like if it was a 12:1 motor this wouldnt be an issue but being cam only I think I need to open it up more.

I looked long and hard into flow tens to start with and finally just had to opt out. I never fell in love with the tone. I definitely want to put in two bullets. I need to look into sweet thunders as well, but I have unlimited options here since its all custom

The Borla Pro XSs are not for you, they are an extremely quiet muffler. I would recommend Dynomax Bullets for what you want

What catback did you have before the duals? Any true dual system should be a lot louder than any catback. But, for what it's woth, Dynomax bullets would give you what you're looking for.
