    What muffler combo? (m30, 3" pipe)

    Im wondering what combo of mufflers to run on my upcoming m30 swap. I am thinking about purchasing a spintech street muffler (which will be loud) and was thinking about another muffler before or after this. Im looking for something that I can definitely hear and sounds good but not near as quiet as stock. The car currently has a stock m20, stock duals, catless, into a flowmaster 40 series. The car is loud and I like it but something a little quieter would be nice for cruising and with passengers.

    Would a spintech with another 'loud' straight through muffler still be real loud? As i thought about using the spintech with the current 40 series but dont know if that will be any quieter.

        You are going turbo with that 3" pipe right? If not, then 2 1/2" is probabaly better.

          I plan on going turbo down the road, so yes, that is the reason for 3"

              Nobody?? I guess my main question is, will two 'loud' mufflers be mediocre? I love my car with the straight pipes and flowmaster, but I would like to be able to carry on a conversation without almost yelling, yet still have a decent tone...Also is 3'' really to big? Im pretty sure my brothers car (that this motor came from) was running dual 2 1/4''....

                I purchased a dynomax super turbo hoping that it would be quiet enough but, its not.... Any ideas on how to quiet it down more or what muffler to use with the dynomax? I want a little tone but not to loud..

                  My Dynamax VT is going in today. I'll let you know how it is once it gets some hours on it.
