haha +1 ^ I ran it open headers for a day til i go my shorty h pipe.

but for the ops question...
I've tried it before it sounded pretty good to me like it didnt just sound like loud crap it had a tone to it but was a headache after driving around plus i got tailed by a cop twice the same day all the way to my driveway lol. I shifted into 5th doing like 35 haha. I had lt's and a high flow catted h pipe so that might be why it sounded a little better than the stock manifolds and h pipe with no mufflers maybe. But in all honesty it was just too loud for me at least.

I guess this is the cheap redneck way! Just put mufflers on it.

my neighbors hate me because i have no mufflers. i dont speed in my neighborhood, in fact i go slower than i do in my other car. but since its so loud they always complain to me and claim i am speeding, they have even called the police on me. my buddy lives 4 or 5 blocks away from me and he can hear me start my car every morning lol. everytime i see another mustang guy around, they always aask me what kind of motor im running lol!!

I just pulled my stock mufflers off. Stock everything else. Any way to stabilize mid pipe from bouncing around? Cheap way to make it loud. 07 gt premium
