SLP
I have never heard of SLP until i found a few videos of stangs on the net, is this one this loud only because of the shaker and SLP? Just very curious, i want this sound...

I have the SLP LM's but they don't sound like that video....
But they do sound ****ING awesome!
but honestly, in my opinion, they sound nothing like the videos on the internet. but they do sound amazing in real life. they are deeper then what the videos make them out to be.

I have SLPs and I just wanted to add a +1 to what Arwing said... videos dont do them justice. I seriously scare the hell out of people walking on the side of the road when I drive by, and in a parking garage, well... better get used to car alarms. SLP was always a more GM oriented company (youll find the Maro and Fbird guys with SLPs everywhere, and they even came on some sport packages) until the LM1 & 2 came out for the new edge Stangs.. Personally I think the O/R Borla setup sounds better for the new edges but for our cars SLP took it hands down. JMHO
The SLP Loud Mouth's are great. I have had them on for two years and would not change them back.
Great for setting off car alarmsand warning the kids that dad isjust around the cornerand down the streetand is coming home fast.

SLP Loudmouths are great for also having fun with Ricers...I love watching the Honda Civic rev up and you here the whining and then let out the throaty sound of the LoudMouths on them and have them look at you like "O My God" Its fun to smile and laugh at the young Ricers.
If you get just the SLP LMs it will NOT sound like it does in the video. Among other things, the car in the video doesn't have cats, which adds immensely to the sound. And although it sounds good in the video, trust me, its so loud in real life your head would probably explode.
With that said, the LMs are still the best axleback on the market.
