New Exhaust for the BMW M

I was able to pick up a used Rogue Engineering El Diablo Exhaust for cheap a week or so ago.

 

I've finally been able to install it earlier this week and get some video of it.

 

Enjoy!

So it only replaces the Mufflers at the end? Are there still big gains to have when doing a full exhaust vs. just the mufflers? Other than that sounds good, sounds like a BMW.

 

There are no full systems for the Z4M. One company just produced one and runs in excess of $2.5k IIRC.

 

You are correct, these are just mufflers. You can buy an aftermarket X-Pipe that deletes the resonator and will make it louder. You could probably remove the secondary cats in the first section which sits before the X-Pipe and create your own full system

 

The gains would really only be from lost weight. A tune can probably help increase some power, but on a NA engine like this there is little to be gained without headers. I lost around 15 pounds on mufflers
