Is this exhaust system a good investment? I'm thinking about buying one. I heard a recording of the system installed on a Tacoma but I couldn't tell much by listening because the recording is very short. It didn't sound much different than what's already on the truck. I went to a couple of Toyota dealers and they didn't have it on any Tacomas on the lot. It's expensive so that's why I'm asking the question. Any insight would be appreciated.
