And the truck makes even better "popping" sounds, etc., on trailing throttle. The power is impressive, too. ;-) You ride an enormous wave of torque all the way to red line. Highly recommended, even though pricey.

Thanks for the update. I have been waiting for someone with a 50i to get this installed. I was planning on installing it in a month or two. I understand this is installed for performance. That being said have you noticed any difference in your fuel economy. I have the 50i also and did not buy it for fuel economy, just curious..
Thanks
