A friend of mine is running straight pipes on his 230. He's got langdon split headers and just straight exhaust tubing the rest of the way back. He drives it daily...in fact drove it out to bonneville this past year from ohio. It's loud and he likes it. You can hear him coming from about a 1/2mi away. Definitely has a distinctive sound. If it was me, I'd probably run at least a short muffler to mellow out the harsh loudness. I like to be able to hear abnormal engine noise and it's pretty hard with such loud exhaust. Guess it's what you prefer that matters.
