SLP Loudmouth I or II??????

[TRIBALMAN23]

I already have and off-road H-pipe, so no cats! and just have stock mufflers on my car currently, just pipe up to the mufflers and it sounds good but........

I have looked all over youtube and still can't figure out what is better.
With my O/R H-pipe is the SLP Loudmouth I or the SLP Loudmouth II better?
What are the differences between the two?
Can you post a video or explain what each combo would sound like or describe the differences?

Wouldn't be the same if I didn't do either one and just ran straight pipe all the way to the bumper? What are the Pros and Cons to this?

Any info would greatly be appreciated!!!

Again I would like to see the differences in the 05-09 mustang models, I think the results would be different on earlier models.

Thanks!!!!!!

no such thing as I and II. they have loudmouth and powerflo only.

HUUUUMMMMM OK i saw youtube vids that had them listed that way and other forum sites that described them that way also.

So what are the differences with O/R H-pipe and and the loudmouth and powerflo?

lm1's don't have mufflers, powerflos do.
my buddy used to have an o/r h and lm1's on his 07 gt, and it was INSANELY loud. sounded pretty much just like my car (i have an o/r h and lm1 catback exhaust, the only difference is lm1's come with resonators for 99-04 mustangs).
with powerflos you'll get a nice deep tone, it's not gonna be as loud as lm1, but it still will be pretty damn loud

loudmouths are just straight pipe with tips. the powerflos are round body mufflers.

It will be obnoxiously loud with O/R pipe and loudmouths. I have no idea what the powerflos sound like.

check out SLPs website for details on either setup, but i would not do loudmouth and O/R H.

I just installed the axle back power flos on a catted h pipe bullitt. This combo is plenty loud .With off roads and loudmouths you might as well just run open headers.

SLP has the "loud mouth" and "loud mouth II" resonators/mufflers, the I series are just resonators (a larger chamber, but empty) the II series are basically strait through mufflers.

I understood you. I guess a lot of people don't think you can splice mufflers into an exhaust system or that no one ever does it ...
