Finished install this past weekend, and what difference at least 150 degree drop in EGTs turbo spool is much faster. A must have for performance enhancement.
Awesome product

Just installed this manifold on my 07 5.9. I must say a very good investment. Dropped my egts a lot and when I say a lot I'm talkin a noticeable 150 degree drop. And the turbo spool time is so much more quicker.
Tough Product

Installed this with a Banks Power Pack w/ Economind tuner and it works great. Can't comment on EGTs since I didn't have a gauge before. Only downside was Banks has a 1/4" fitting and this one was drilled for two 1/8" fittings. Drilling went ok but I broke the tap off then had to take it to a machine shop. They saved the threads and got the tap out but had to buy a new tap to finish tapping, their old one wouldn't cut. That stainless is tough, hope that is sign for future durability.
Good product

Man did this thing drop EGT'S!!! I was really shocked what this product did for me. lowered exhaust gas temp by 250 degrees pulling heavy loads. Hard to believe! installing was a bit tricking having some heads striped before I started. it was the #6 that was the worst! The turbo... Had to tourch thoses babys off. there was no breaking them loose!! I went ahead and got the BD gaskets. highly sugguest you get them! Start to finish was about 2:30 min. The blade runner is only 100 bucks more than ATS or BD but worth every cent! Im one of those that shops and reallly reads up on things before buying and I dont think any other after market product can compete with this AFE! So dont think twice about which to choose from!!! Thanks XDP!!
