Maybe you just went with the wrong muffler. After I installed my cam, headers & ORY, I replaced the SLP resonator with a Magnaflow bullet muffler & it's still loud as hell, but just eliminated most of the rasp (only time is 2500-2800 RPM under light load).
before u up and waste money changing it let it be for a month or 2. Magnaflow tends to get louder as you put miles on it. I have true duals on my car and bought 2 magnapacks for it. Put em on and loved the way it sounded but it was to quiet so I put my 40 series slowmaster back on and went about my business. Eventually I wanted to lower the car back down again so i put the magnaflow back on and had the exhaust guy tuck them up good. Been driving it for a couple months now and it's louder than my flowmaster was. And it sounds tits by the way

I had the slp LM1 with my current set-up and it was VERY LOUD and VERY RASPY. I changed it to the Magnaflow CB and its a lot quieter but I dont really like the sound all that much. It sounds sorta stock but I can live with it. Here is a sound clip of my Magnaflow
Man get a dual exhaust custom made and dump it at the rear axle, I was just in your same shoes. With my cut out closed my Bassani x pipe dual exhaust felt to quiet, with dual cut outs it was so loud I would set car alarms from 100 feet away. So I had them cut the over the axle part off and weld on two glass packs and the sound is freakin MEAN and perfect. Loud all the time, but you can still hear the music.

SGM K: Sign your counseling form.
I don't want to offend you, but make sure you put the muffler on the correct way. If its backwards, it may be very quiet. I'm sure you've already checked this though.
you should look into a Hooker Aerochamber muffler sounds really really good with no droning inside vehicle but really screams @ wot. I have lt's & ory & have no rasp.
My Magnaflow took some time to break in. When I first put it on, it was very quiet and my car seemed slower. After a few days the sound really opened up and it sounded much better.
I know someone else already asked this but I never saw a answer. What cam do you have in this car? In your sig there is no sign of you having a cam but you did say that you couldnt tell you had a cam after you changed the muffler.

your problem being... you put a muffler on your car!!! hahahaha a loud mouth exhaust is pretty much no muffler.. the lil resignator they give you is nothing.. just looks like a muffler, if you look inside it there is nothig!! less than what you bolted back on hands down hence its quiter now, youll probaly see in new "muffler" theres dimples, or hell even chambers, all in all cant get louder than a loud mouth unless open headers, seeing a loud mouth does nothing to quiet exhaust noise, at end of y-pipe back
Funny you guys talk about your exhausts being so quiet you cant hear them... My flowmaster 80 on my six is freakin loud all the time. I cant imagine anything on your v8's.
I'll be going to a v8 takeoff catback next since I have an electric cutout. Its nice being loud and/or stock quiet when you wanna be.

Its loud because you dont have enough exhaust pressure to use the muffler as it was designed.
