Glad to be back its been a while since my last post i hope all you are doin good. Ive been wanted to do some performance mods on my 04 LT but i am stumped as to what i should do to still keep it low profile, but still maintain great performance. With the vette servo im will it change the way the whole car feels and drives? and im not quite sure what the blackbear tune does as far as performance goes even after doing some research. Last but not least i want to change my muffler into a little more deeper sounding idle and roar but i don't want to go over the top..just a step ahead of the stock muffler..i would love any input you guys might have on this thanks alot
