Hello I have a '03 Chevy single cab truck. It has the 5.3L V8 engine. The only thing I have done is put in a K&N Air Filter.I bought the truck used about 6 months ago and the first owner has already put on a Flowmaster muffler. I don't know which model it is but it sounds pretty good. I like a little louder sounding muffler and this one is not doing it for me. Do ya'll have any suggestions for me.

Thanks.

 

Depends on loud you want. Dynomax bullets are a good, loud muffler; and have excellent flow. Hooker Aerochambers are another that flow good. They aren't as loud as the Dynomax but have a good sound with little resonance.

 

I have the dynomax tube muffler, not the bullet, but the tube/round style.. Its like 70-80bucks I believe. But it has a nice deep sound and im pretty sure it flows good since its straight through

magnaflow flows good, but its not gonna be very loud

bullets will be loud

 

My Magnaflow is loud!!! Its louder thatn a few peoples cutouts

 

I'm looking at a 4.8 and i want it to sound better. I used a dynomax bullet on my Z28 that sounded great, i'm wondering how it would compare on a 4.8?

 

My magnaflow is pretty loud too! I have my cats gutted too though.

 

crewcabondubz has a SLP resonator in place of his muffler and its louder than my cutout...i havent taken a ride, but he says the resonance isnt bad at all. the resonation a cutout will drive you crazy
