It sounds good and are you pleased with them. I was thinking of putting them on mine.

 

yes i am very pleased with them......they have a very agressive sound, but arent too loud when your just cruising, but when you hit the throttle it sounds amazing

 

Totally agree "vert"... I originally had these after listening to a vid on youtube on my 05 GT... when I got the GT500 it was a 'nobrainer' to put these on it as well! LOVE 'em.
It may be a little too loud for some, but for me it's exactly what I look for in sound. And as you say, not too bad when cruising, but WOW at WOT!

 

add that with the supercharger whine, and sounds like heaven to me haha

 

I just put the SLPs in my 2010 and I am very pleased! I think with the stock system they have a perfect balance of noise yet are not obnoxious.

As far as some people saying that there is a loss of low end torque, I have not noticed any change as far as power and response. My car is still very responsive and lights up the tires at the same rpm and same gears.

 

I also love them. I was surprised that they weren't louder than they are. Love your Kona Blue, excellent color combo.

 

Thank you! I am blown away at how perfect these pipes are. Only bad thing is that now I want to drive the car all the time.

 

Have these on my 500, the best axleback IMO. Still very quiet inside car, almost to quiet for me. But outside it's loud!

 

I am in the process of uploading some videos to youtube, I will post links once they are done. I agree about the sound aggressive yet level out and are quiet at lower rpms. I do like my Ford Racing Sport exhaust but the SLP is a bit more aggressive which I like.

Now if someone would buy the FR sport exhaust I am selling I'd bet set!

 

That car has a very nice rumble!

 

So this system removes the mufflers? Correct?

 

Yes, it removes the mufflers. Here is a quick drive by (my car only has the SLP loudmouths, the rest of the system is stock)

 

Next question.... No mufflers legal in Texas? I thought that would be required for inspection.

 

The loudmouths are 50 state emission legal (of course). I'm guessing Texas has plenty of trucks and cars with no mufflers, but I don't know the law!

IF you are concerned with having a muffler, you can always go with another type of axle back system which replaces the stock muffler with a louder muffler.

 

If they are 50 state legal for emissions I'm sure I'm good then. I really like how sound of that system!

 

As long as the system is cat back or axle back, you're good to go on emissions!!
