I just did a DPF/CAT delete, S&B Cold Air Intake, and H&S XRT Pro. I'm using the factory down pipe and the factory exhaust behind where the DPF was. It is also factory mufflered in that area. I love the sound! Not loud at all even at highway speeds plus the factory pipes in the rear make it look like no mods. I took a 75 mile trip today while tuned to the HD300HP. Wow!!! 0-60 in 3/4 of a city block! Before the mods I was running 70 MPH at 1950 RPM's now I'm running 1750 RPM's at the same speed.

The XRT Pro is an awesome tuner! Better get one before they are sold out. As gunman41mag has pointed out: THEY ARE NOT ALLOWED TO BE MANUFACTURED ANY MORE!

Fellas, here's how scarce they are becoming: I almost bought one this summer and at the time the XRT Pro was $599 (it was NOT the street model). They started going up in November and by last month they are now $1399.99. That is nuts!!!

Here's what the EPA needs:
