The 328i and 335i were 07+ models. 328i replaced the 325i while the 335i replaced the 330i. All 3.0L engines with the latter being twin-turboed.
In Canada we also had the 323i, which came with a 2.5L.
ohhh i see well damn because i heard the remus on that 325i abd it doesnt sound worth the $1300 however i heard it in a 335i and it sounds sexy as shit but maybe that could be becuase the 335i wasnt stock?

The stock exhaust is slightly different but aftermarket systems are free flow so it is all about note and style.
yea for my car exhaust is just about sound preference because performance gains are shitty with these n/a little v6 motors :/
