i have an 04 chevy silverado 1500 2wd. I want to get an exhaust thats as loud as i can get it. Personally i like the dumped look better, anyone got any suggestions?

 

Flowmaster 10 series would be the loudest.
Plus you could put on some new performance headers.
Puting on throttle body spacers will give you a bigger combustion and louder sound,
And puting on a cold air intake will net you more noise under the hood too

 

im tryen to figure out the same
i want loud but deep
i looked at 10 series but all the vids are crappy

this video is pretty good quality.
and the silverado in the vid is only a 4.8 litre too

 

glasspacks are pretty damn loud, but the sound quality is horrible.

 

or you could delete your muffler and straight pipe it.

 

Not so sure you want to cut out your muffler.
A lack of back pressure is gonna get your valves all out of wack

 

mile wha kinda tone does your 40series give

 

I have the american thunder series on my 2005 Silverado and its pretty loud.

 

i put flowmaster 40s, cat back, singel in, duel out on my 09 silverardo, v-6, 4.3, sounds good, not as deep as i wanted, but i think thats because of the v-6, usually had v-8. i am very happy with it .
