Hey fellas, I read the previous posts regarding the aero-turbine, but the last post was June. I'm wondering if anyone is currently using the aero, and what they think about it. Is it any better than a straight pipe, or any other 4" system for that matter? This will be the only upgrade on my truck. I have a 2004.5 LLY. Thanks for the help

just straight pipe ithttp://dieselplace.com/forum/smileys/smiley4.gif.

The aero turbing people make some pretty extravagant claims for those mufflers. I spoke with someone who tested one on a diesel. Ran it up some long mountain grades and said the truck had a lot less power.

I also have heard good things about this muffler, from the shop trying to sell it to me, nothing from an actual buyer. Ive ben waiting for someone on this forum to try one and let us know.
