bmw pi and engine sound

accel · 10-03-2011, 10:07 AM

I'd like my 328i sound similar to 330i zhp. Will bmw pi help?

Pe is really loud per my taste.

I thought i've heard accounts that the PI doesn't enhance the sound much at all. I could be wrong though.

open intake, and a free-er flowing exhaust will make a sound difference, but my 330i didn't sound all that good stock...
Unless you're referring to an e46. Then I can't say I know what they sound like.

it changes the tone a little, more deeper, less high pitch wine.

never heard the e46 330i zhp sounds so couldnt tell how it compares.

If you have Pre-LCI model, you can also remove the sound insulation attached to the hood. My LCI sounds better compare to friends Pre LCI model.

Change is marginal. However, as per the above post you do get a deeper tone in the engine and you can definitely hear it from inside the cabin.

There is a pretty big change past 6000 rpm. I actually use it as an easy way to time shifts. It's a lot louder throughout the whole rpm range outside the car though.
