    Question Flowmaster "50 Series Big Block" muffler ??

    Thinking about changing my muffler and I was looking at the Flowmaster made specifically for the 02-06 style, the 50 Series Big Block. Flowmaster rates it as mild sounding and I would like it to be mild BUT does anyone have experience with this type? Thanks!

    LOUD... I have a maganflow 12599 muffler which is dual 3 in, dual 3 out. I did a lot of research before I got it. It still has a little rumble to it, but it's more mild than any flowmaster...

    Blowmasters are terrible mufflers. You need to pay the extra and put a Corsa Touring on there. You won't be disappointed.

    I have a "80 series" on my 03 ESV.

    Love it. Sounds awesome at idle. It's not quiet though, ever. When you romp on it, it sounds really good.

    I can easily hear my wife start the truck in the driveway when I'm in our house. I can hear it coming down the street when she comes home as well.

    Some might not like that. I enjoy it though

    Ah crap, nevermind I decided to keep the Escalade all "caddy-like" and quiet. BTW, just wondering did any of you guys get any mpg or hp gain with a different muffler?? Thanks!

    caddy like? all quiet??? most of the new caddys have a stock rumble to them. my 2000 is real quiet, i would love it to sound like the 07-09 escalade. my brother had 1 and when you hit the gas it gave a nice rumble. i wanan put a muffler on but i dont want it too loud, i have a race car for that...i just want a nice little rumble, i just dont know what to put on

    Was going to post this but I will resurrect the old thread...

    Anybody else have the Flowmaster big block on there? I'm not too concerned with overall loudness but I am concerned about the drone on the highway, etc....

    I don't feel like spending a lot of sash on a cat back dual but only want to replace the muffler...

    I had the 50 series big block on my '04, and there was no drone at all. The truck sounded factory at highway speeds. Honestly, it wasn't loud enough for my taste. So now I have the 40 series on my '08 escalade, and it sounds mean.
