I just add on new straight muffler, but the sound not loud...and i on auto tranny,
so, if remove the ori muffler, the pickup will sucks.....
any recommend beside go for S-flow muffler, since i brought and install already the straight pipe muffler...
anyway to keep the back pressure?? two bullet ? instead of 1 bullet now using..
and the piping is original diameter...
