No mufflers or o/r h and flows
 

So right now, I have no catback on the car and it sounds like complete poo.I have the stock h pipe though. Its not as loud as I thought it would be though. Anyways, I have a o/r h sitting in my trunk and i'm waiting for my American Thunder catback to come in. My question is, would the catless H and the American Thunder catback be louder then no mufflers and stock H?

Thanks.

It won't be louder per se but the catless H and Flows will sound much better
I run that setup myself

h pipe is the way to go. Had o/r h with flows and loved the sound, now have stingers and love it even more!

got an o/r h with flows and it sounds badass! of course, i have LT's as well, so that changes the pitch a bit, but i still strongly recommend. everyone has an o/r x these days, i enjoy having that distinct, more muscular sound.

im running lts, o/r h, and flows. i dont think it sounds too bad. ill be looking for bullet style mufflers in the future
