3" muffler's for performance

I guess my thinking was that I needed to get something that would flow the number the first time. However, the engine I have now could probably run a 2.5" system and be fine.

I have the $20.00 each Summit mufflers on my work truck and I don't find them objectionable.

Just thinking aloud here. Also, trying to look to the future and make sure that I have things well planned for later.
