Most everyone here got their upgraded down pipes from ats diesel performance. You will have to give them a call because its not listed on their website.

how much of a performance diffence does the downpipe and housing upgrade give you. Its like $269 for the housing and $89 for the pipe I just want to know does it really do that much for the truck.

I have not done the upgrade myself yet but i've not come across anyone that regretted buying it. From what i understand it gives you a bit more power, truck is more responsive, and much lower EGTs. If you do a lot of towing it would be a good thing to get. Just don't expect it to make your truck feel like its got a powerstroke under the hood.
