I would agree with Brian ... you should have saved the muffler...I purchased a straight pipe for about $50 bucks... yeah the sound was awesome..but what I found was that boost pressure bled off faster.. I went back and fourth a number of times between the two pipes... the car held .8 with the muffler... the internal baffles held the pressure better while with the straight pipe I would hit .8 and then watch the pressure gauge back off a bit to .6 while still heavy on the throttle... I am not sure if this would be the case with a different WG such as a Tial.

my 2 cents.
