It usually provokes them a little more when you pass by them going the same direction at twice their speed and WOT....

 

 

My favorite is the Megan OE-RS though, dumb quiet inside, still sounds great outside, not obnoxiously loud, decent weight savings over stock (but not nearly as much as a single). I'm also partial to the Nismo exhausts, but they're obviously harder to come by. Living in Cali, I would think you would want to keep it on the quieter side...

Just realized you have a sedan, so you're much more limited.

 

Ordered the Megan for my sedan a couple years ago and even then it turned out they didn't have any in stock, weren't able to locate any and had no idea if anymore would be made for the sedan. Ended up with the quiet but drone prone Tanabe instead.
