It ROCKS!!!! I thought about getting a muffler but decided to try the pipe first. No turning back now! It is loud, sounds like an 18 wheeler and I've had a few looks already (smiles and frowns!). On the highway it's not too noticeable unless you're on the gas or a grade. Passed the girlfriend test, she has no issues at all. Waited too long, glad I did it! I'm sure it will be a headache the first time I tow...but I don't do that too often.
