The loudmouths were my first mod. thought they were to loud installed a different axleback system and had tons of drone and no where near loud enough. then I heard another car with loudmouths and put mine back on the next day and loving them since

Iam about to pull the trigger on a O/R H pipe to my slps. Ride with your windows down, it sounds so much meane,the cabin is very good at blocking out sound with the windows up.

I love the sound of my SLPs when I get on it, I just wish it was louder at idle. I envy all those Fbirds and Maros with their deep, loud idle roar.... guess thats what you get from a 6 liter engine though huh?

I mean the idle isent LOUUUD but its a nice deep low tone rumble. I really hope the O/R H amplifies this. I love loud so i hope its nice.

I got mine from lm performance on monday afternoon for $299.95 and got them tuesday morning at 9:00 in the morning by FedEx!!! Wow! And no charge for shipping!! Granted, i live in GA which is close to their warehouses, but FedEx, come on now! That's incredible. Also, they sound awesome! So much better than no axlebacks at all. Plus no drone at all. Great package!!!
