I have narrowed my exhaust's down to 2. Of the 2 I am unsure. I have a '05 mustang gt and am looking at either the SLP Loudmouth or the Flowmaster American Thunder axle-backs. I am trying to get that grumble sound but I don't wanna wake the neighbors up but I still love the loudness. Thoughts?

 

dont be a pussy just cut the exhaust off at the y-pipe

 

LOL, trust me I have thought about that But I am just a casual driver, I don't race or anything. Just like the great sound of that V8 ;D

 

I think the SLP system sounds more agressive, Id go with that.

 

I know slp's quality is pretty shitty as far as my 4th gen camaros went, I don't know about flowmaster. It's a personal prefrence thing anyway though I'd assume. Try to go out to a mustang meet and see what you like

 

Have you heard the loudmouths on an s197 in person? They sound "okay". They are a little too raspy/pick up truck sounding though, especially on decel. If your hell bent on those two options i would get the blowfasters. If your looking for stuff around that price range I would say take a look at the pypes mid muffler system.

On second thought I vote this

And spend money on some cams

dddooooo eeeettt!!!!

 

Of the 2, I'd say SLP, the flowmaster is too quiet in my opinion.

 

Bassanni exhaust FTW?!

 

no cats and some 1 chamber flowmasters....i think american thunders are 3 chamber, i wouldnt get more then a 2 chamber
