I'm considering putting dual exhaust on my 05 X, but I looked under my car and noticed a couple things in the way.

First, the rear sway bar. I was wondering if it it possible to exchange a later model OEM sway bar that has room for the second pipe with the stock one.

Second, a black box with fuel lines running out of it. I am not sure what this box does, and am not sure if it would be safe to move it, possibly to the trunk.

 

The black box is the fuel evap canister. A few Sedans (not Xs IIRC) have done a dual exahaust and relocated it to their trunk.

Thanks, this looks like my next project

 

do it!

 

Here's my setup:

I was able to keep the evap under the car, as I didn't want to put it in the truck because of fuel fumes. Some people seal it and stuff apparently, but to each their own, I didn't want to take the chance. The thing is though, if you want to fit a muffler in that location, you have to move the evap completely. I just put a muffler in the middle of the car and two pipes back, and there was barely room for the pipe, even after I relocated the evap and moved it vertical instead of horizontal.

 

Interesting, did you happen to snap any pics of the relocated evap? This is something I'd be interested in doing.
