My car is on a 3 year lease but was wondering if it's possible to mod it (intake and exhaust).

What's the best intake and exhaust combination out there for the E90 328i. I want a deep warm sound.

I think that the intake is a void, but depending on what you mean by mod, muffler only would be okay.

I can't tell you what the best combination is because it all depends on what you're looking for.

Some people like the really loud sound, which is having both the intake and muffler/exhaust, and others like the subtle, yet noticeable sounds.

I can tell you from what I'm seeing lately, it seems like the Gruppe M Rep is pretty popular, and it sounds pretty damn mean. Also, the Rogue Engineering (RE) Ikon for the e90 sounds great too. I'm thinking about getting that myself.

From Dougman's thread for the RE Ikon:
