well my flowmaster muffler is back on sale due to the local jerk who was gonna buy it from me not having any dough. he wanted to install it and he wouldve paid me the following week. yeah right.
Well if your a 2.4 than ur pipe diameter is 2.25. You should be able to get a pipe adapter that has one end at ur size and the other at 2.5 diameter. That's the same diameter of the muffler. And no it ain't high pitch. It's nice and deep.
