off road H-pipe on 2006 ??

Mils work on my 05, dont see why they wouldnt work on a 06. Get the Pypes off road H, very easy to install, sounds great, there are some sound clips here.

they claimed that the MIL eliminators wount work on S197s. well, they have been successfully installed on many S197s with minimal problems. a few have had to replace the MIL eliminators then it worked fine. my guess is a defective MIL eliminator to begin with. since you already have the parts, try it out and see if it works. if it does not, then buy an SCT XCAL 2 from brenspeed after you get your O/R H installed. brent is a good guy and will help you out. you can also call him and he has no problem answering your questions.

if you order the O/R H and the tuner at the same time, he ususally cuts you a little price break on shipping. i klnow he did this with the MIL eliminators, but he just had to toss those in the H pipe box.
