I just put on the MAK off road X pipe & wow is it loud . The quality is 1st rate - perfect fit. I did it myself . I also have the shorty headers. It feels like I lost a little power down low and picked up a little something in the 5-6 rpm range. for $199. well worth it http://www.makperformance.com/category.cfm

. I have a before Dyno so this weekend I'll get it dynoed again to see what gains were made - stay tuned.
