It won't. I recently passed CA smog with no problems.

Speaking of smog test...where did you take your for the test? I'm assuming that the test station would have to have a 4wd dyno? Thanks.

Any smog station. A 4wd dyno is not used for the test. They just rev the motor in neutral to the required RPM.

The Remus system looks really good....love the stainless steel tips with the logo!

Congrats, looks a lot better. Well done.

DKL, looks great!!!!!!! Do you have a video so I can hear the REMUS setup? Also, where is a good place to purchase the Remus setup and is there a particular model? Thanks so much!!

It may look like a 4.4i from a distance, but rest assured that most drivers on the road don't know about a 4.8 tip vs. a 4.4 tip. I think the double tips you have now project a lot more power, and are more visually strong than the previous look:thumbup: Good job!:thumbup:

Sorry...I don't have a video or sound clip. Take a look at Zerochief's video and sound; it's not as loud on the little 3.0i, of course. There are also a few clips on youtube as well.

You can pick up a set of Remus at Bavauto and a few other places. I got mine slightly used from a forum member here. There's only one Remus model for the X5.
