Default Loudest Muffler?

Well right now I have a flowmaster which I'm starting to think was a bad idea from what I hear on here so thinking on replacing it, I want the loudest muffler I can get that wont lose me power like my flowmaster, I just have stock manifolds right now but plan on headers in the future, thanks for the opinions in advance!

the SLP LM1 (loudmouth 1) resonator is probably regarded as the loudest thing or dynomax bullets

Do you like the sound/tone of the flowmaster though? I would get a cutout like others mentioned.

The exhausts like the loudmouth get way too loud and raspy once you start adding headers and a cam.

I think LM1 is the loudest. If you want louder get headers and y. Not necessary with the LM1. I have obx headers and y wiith LM2 and like the sound. Dont know if its loud enough for you.

I have a loudmouth 1 with headers, ORY, and a big cammed 6.0. It's too damn loud if you ask me, I like it but it's really an inconvenience around cops. I'd rather have something quieter with a cutout now, but back when I still had cats, manifolds, and a stock cam the car had the perfect level of sound for me. Seriously at this point my wife can hear me coming home about a 1/4 mile away, if I get on it she can hear it about a 1/2 mile away, and knows it's me. I'm not talking about out in the country either, I live in an apartment complex right off of a main road. She has enough time to walk outside and open the garage for me and walk back in the house, lol.

I have LM1 with Jet Hot LT's and Catted Y. It's pretty loud, but not unbearable. I don't have a bigger cam yet, so I may change my opinion of it when it comes time for that upgrade, but for now I like it. It's definitely not as bad as some make it out to be. I have sound clips on youtube if you wanna listen. Just let me know an I'll post them.

LM1 is the loudest. As far as just the muffler goes, its not the loudest but Id recommend Hooker or Magnaflow.

If you enjoy the sound of your exhaust more than listening to the radio, then the Loudmouth and headers are definitely the exhaust for you. If you want something that is loud at WOT but quiet enough that you can hear the passenger screaming, then the Magnaflow CB may be a better option.

No muffler.

What's the point? Just to be obnoxious?

I would spend your money on something to make the car faster.

get a good muffler and put a cutout on, youll be hating yourself everytime you need to take a 15 min drive somewhere if you put on a LM1.

I have Hookers, ORY, and LM1 - I don't like it to be honest. It sounds mean as **** from the stands at the track, but driving it around its really raspy. I'm afraid to ever get on it since the cops around here are asshats.

I have nothing but a lid and LM1 cat back right now and it sounds perfect. Once I get the Y and LT's I am sure I will have to find a quieter muffler to put on it.

Well seems like the slp lm1 would be perfect, I live in a country area and our nearby town is only small, people and cops are pretty easy going we never get loud car complaints lol
