Magnaflows have a large casing. This will cancel sound waves more than a typical casing.

i know its going to be loud, im not looking to be quiet. I just want it to be as quiet as possible with True Duals. Right now ive got a Y pipe a SLP LM2 muffler and a turndown after it. It's louder than most dual setups ive heard. I just want it to be quieter than what it is now.

i guarantee that your current setup is louder then my duals with magnaflows

my previous y pipe setup was powerstick in the i pipe with a cutout, and that was way WAY louder than my current duals and 4x9s.

I wanted somewhat quiet but deep too. Cats will really tone it down no matter what muffler you choose. Without hearing something in person, it's tough to know how it really sounds. We can discuss this for the next year and it won't do much good without hearing it for yourself. Even listening to those on ls1sounds.com isn't very helpful for me. I bought a welder last year and I'm on my 3rd exhaust setup. Either it's to loud or sounds like a pickup truck. My latest experiment is duals, no cats, 2 PowerSticks and 2 Flowmaster Super 40's. I've only cranked it up once on jack stands, but now I think it's to quiet.

Edlebrocks are pretty tame. I used to have them and they sounded nice.

I bought some magnaflow bullet style mufflers for 50$ each to put after my x-pipe. 14 inches long. I hope those will tone down my duals but I still want it to be loud. Anyone heard that setup btw?

i really enjoy my spiral flows, i never knew tsp carried them until my friend told me about the options they had when he ordered his (i had mine custom made for less) i like how they are "quite" compaired to the other two and when on the freeway, it's pretty quite, you just have to talk alittle louder, but nothing some sound insulation can take care of

Quietest muffler hands down is between the magnaflow 4x9's or the Borla XR-1 ovals.

I have long tube headers, 3 inch collectors, to 3 inch piping all the way back, 3 inch x with 3 inch moroso spiral flows. Im not saying there quiet, but they sound great and i believe any one into cars could drive them around on the street without to much problem. Im dumped at the rear axle, and if im not getting on it, its not to loud at all. If im pushing it to redline then it gets loud, and sounds great. Alot of people going the td route really love the moroso spiral flows, and im very happy with my choice. There definatly quiter then the bullets, only other td's ive heard on a ls1.

oh yeah i forgot to add that i have mine run all the way to the back and it dose make it quieter than just dumping it at the rear end. to me the spiral flows have the most "uniformed" sound out of those other ones

Magnaflow 4x9's were much quiter on my X pipe TD's than the Flowtech Afterburners which I had originally installed (when I had the SS).
