i went and had my car dyno tuned yesterday it put down 328/338 right now im running a 2 1/2 TD setup with now mufflers will i gain any power if i add bullets. im think spiral flows or twisters one place in town told me to put glass packs on it.

 

depends on what kind of mufflers you have on it now.........
most likely if you have a "performance" muffler, your gains will be minimal.

 

is that "now" supposed to be "no" mufferlers?

...straight pipes is the best performance you can get = no restrictions, free flowing

 

yea now is supposed to be no

 

Put some Powersticks or one chamber Flows. They won't hurt performance and will refine the sound...a little.

 

yeah, its gotta sound like redneck truck with straight pipes......... single chamber flowmasters sound **** and flow excellelent
