I also have a Remus Romulus on my 01 Boxster. I like it alot. It's a little louder than stock, but noticibly deeper. I especially like what it did to first gear; with the stock exhaust, accelerating in first gear turned into a really high pitch sound that seemed to be saying " shift into second NOW. PLEASE" With the Remus, the car dosen't seem to have that urgent need to get out of first gear RIGHT NOW. Just seems to lengthen it a little. I'm not sure if that makes any sense or not-but that's what it seems like to me. Overall, the Remus note is nice and low, but not too loud (although it sounds awesome in a narrow canyon!!!) I'm very pleased with it.
