Currently I am running stock headers and midpipe. I bought a SLP LMII catback and installed it. It wasnt loud enough so i put straight pipes where the mufflers go. I have heard that I am loosing power. So I was thinking of putting my mufflers back on. Then another friend said to gutt the stock midpipe. What would be best?
1. Put mufflers back on and leave midpipe alone.
2. Put mufflers back on and gutt midpipe.
3. Gut midpipe and leave mufflers off.
4. Leave it the way it is.
