I'm looking to buy an 8th gen si in the spring( had one previously and regret selling it). The first thing I'd want to mod is the exhaust. I've seen reviews on the invidia n1 70mm and the skunk 2 MP r 70mm and they say the exhaust is very loud. Is this the case with all the 2.5in? Yonaka sounds good and seems subtle and fullrace seems the same. I'm looking for loud as in noticable, not loud as in annoying cop magnet.
