I'm who Call911 is talking about in his post. Let me just say that our car with the Loudmouth is a head/hotcam kit w/Mac Headers/Cat setup and I LOVE it. I will freely admit that it can get raspy under certain throttle inputs, but it's music to the ears.

On the flip side, on Call 911's formula, that Magnaflow sounds outstanding too.

 

I voted loudmouth because thats what i have, it can get a little anoying on the highway, but you can still hold conversations in the car. I get nothing but compliments on it, and just the noise will turn heads, just make sure it dosen't turn too many LEO's heads and you'll be fine.

 

I own Loudmouth, an ive had it for about two months now, an enjoyed every minute of it. When looking i wanted something that was loud, a nice easy install, an iam very happy with it. My vote would be for the loudmouth.

 

I voted for loudmouth, that's what i have on my car. I like the way the car sounds at WOT, and i enjoy setting off car alarms all day long. I have mid's headers and gutted cats too, so the car is really loud, my brother has the LM 2, and my dad has LM 1, i think the LM 2 sounds better, but those car are both LS1, and i got a LT1.
