'07 GT with 3K miles...this was my first mod. I was a little worried about how loud it would be, but honestly its perfect. I wouldn't say it's too loud at all, at least from inside the car. Any quieter and I'd probably be a little disappointed. Install was very straight forward, as expected. Just wanted to let people know who might be considering, but worried about the sound!

I'm kind of disappointed. From what I have read on here, people make them out to be SUPER loud...And that's what I want...

Oh well. I'll find out tomorrow when I install mine...

Loudmouths are Sex to my ears.

I love mine, but I agree a little louder would be nice. I do get tons of compliments though, so I know it does sound really good.

Arwing...no worries! They are loud, just not too loud.

i put LMs to my old S197 and they sounded great. like old school muscle car. when you floor it, under WOT it sounds so sweet, you need to hear it!

I just put mine on, OMG do they sound NICE! They just ROAR!!!

On a cold start they are pretty loud. And at idle - stock would be like a 4/10 the SLP's would be like a 5.5/10. Yeah not that much louder...but when you jump on it.. WOOOOOOOOOOOOOOOOOOOOOOW. Man do they sound nice! and under $300!! Can't beat that!
