Progress once again, this time with a new exhaust. Progress may be an over statement. I changed out the dynomax X-flow with a magnaflow 5X8 dual in/out. The car is still no sleeper but I think it may be just a bit quieter. The resonance is definately better. The tone seems just a bit deeper. Jury will be out until spring and I can get it opened up a bit. Everything is loud in the garage.
The internal design of the muffler is quite a bit different. The dynomax has a full X cross flow design. Meaning the X starts at the end of the muffler at the top on one side and ends at the end of the shell on the bottom of the other side. The magnaflow has a straight entry for probably 8 inches then an abrupt X and the another straight to the exit. The magnaflow also uses rock wool for insulation where the dynomax uses fiberglass.
I only need a couple of decible breathing room to stay clean at SCCA events. I am hoping that the magnaflow can do the job without too much restriction.
