Yeah right now its a toss up between a 14" magnapack, a SIDO super 10, and 12" dynomax bullet

I have a 14 inch magnapack with 3" single tailpipe and it has a good tone, not super loud but is very deep sounding. Mines a 5.4 but I really don't think that makes that much difference on these trucks as far as noise level.

If it's too quiet for me I'll just cut off the rear cats, that should open it up.
