Default muffler???

well i am changing my exhaust system on my s10 ls1. right now i have shortys with 1"5/8 headers, high flow cats, true dual 2"1/2 exhaust with slp loudmouth resonators. my new exhaust is going to be 1"3/4 LT no cats with 3" pipe to a flowmast Y pipe. i am not really sure what muffler i want to run. i was think about going back with slp, but i think it might be to raspy with no cats. my good buddy told me i should go with a one chamber flowmast, but i am not sure what i really want to run just yet.

heres a list of what i was thinking about running!
SLP Loudmouth Resonators " the ones with the packing inside"
Magnaflow Performance Race Series Mufflers
Flowmast one chamber
Dynomax Race Bullet Mufflers

so............... let me know what you guys think would sounds good and your thoughts on mufflers or any different mufflers!
also i have tsp 5.3L heads and ms3 cam.

*edit just seen you are asking about bullet style mufflers, pretty much they will all be the same "loud.

But if you choose bullet style still magnaflow, there's a reference of db for each of those mufflers you asked for.

Magnaflow if you want a good, mellow, not too terribly loud tone. I love it.

Go to LS1sounds.com and oyu can listen to different setups.

Yeah I like the bullet muffler sound. I really like the sound of my slp now, but just not sure how loud and raspy it will be with no cats.
I am really thinking about the magnaflow bullet. I just have not head them on anything. I had a dual in dual out regular magnaflow on the truck a year ago. After I did the heads and cam, I put a 40 Flowmaster on it. Then dynoed the truckand lost hp. After that I put the slp's on.

Yeah I have been to ls1sounds and look on there. Just wanted somemore input.

Magnaflow 4" round mufflers/resonators/bullets sound like this when dumped.

They get very raspy with a tail pipe though.

Flo-Pro twister mufflers sound pretty good too.

The loudmouth gets extremely raspy without the cats. Thought about a borla? A little on the quiet side tho.

i have an es tin with an el es juan and a big camshaft. i have the shorty 1 5/8 headers as well. with no cats and 2 1/2 inch dual. i think my magna flows sound like crap ***. i did forget to get an h pipe in it tho.. hopefully that cleans up the sound a bit when i get that done.

I had dynomax bullets dumped before the axle.. Car was loud and strong sounding...

Went to a hooker catback, its amazing what you can get used to.. Haha, i didnt realize the car was that loud before.. I can't imagine what it sounded like passing by @ 7000rpm's
