Quality product but don't be in a hurry to get it.
It was my fault, should have read the fine print on ebay shipping that it takes 10 working days to ship. If I had to do over would order it again.

Ordered the AFE stage 2 intake for my 2005 duramax. Received the order in 1 day. I was impressed that there were several QA inspection tags showing that the parts had been inspected and that all of the parts were there which is important because you don't want to have your truck torn apart and halfway through the install only to find you are missing a screw. The instructions were adequate except the photos were terrible quality and nearly unreadable. Got it installed with not too much trouble but with the bad photos it was a little difficult to figure out which way the inlet tube went. Overall got it installed quickly and it works as expected.

The exhaust arrived on time and was exactly what i was looking for, not to loud just right sounds good.
