Thanks again guys!

Anyone know the sizes I asked about? Length of muffler and the in and out piping diameters??

 

Most of us go with the 3" inlet-dual 2.5" out, but you are in Canada and use a real measurement system. 76mm inlet, 2x63.5mm outlet i guess... Magnaflow is really popular for those who want a nice tone and good performance gains, flowmaster is louder but less performance...the FM 50 HD is a REALLY good sounding muffler on our hemi but may be louder than what you are looking for. The 40 series are even louder... I am sure people will disagree with what I just said, especially since there are no controlled tests for dB to compare, but this seems to be the consensus on the forums. I have been looking because I am about to do exhaust as well.
