Excellent product installed it on my lunch break which is only half an hour and I already ate my lunch. Instantly changed my idol to very smooth and a little quicker for a response at idle, a slight difference in throttle response while driving which is great. The cheapest and best mod you can do to any 7.3.

Great product, had it in about 4 years now. Just bought another for my other 7.3L.

This tube made a serious difference in my idle and overall performance.. thanks again riffraff

First off, its a tight fit but does not require modification.

2nd - I did not notice any noise reduction like bros talk about, though the exhaust on the truck has been modified.

3rd.- I did not notice any performance gains, though the truck is more consistant at lower throttle.(less go pedal is needed).

Lastly. The owner of the company answers the tech support phones here. And im not the first to make that statement, At the end of the day you cant beat that.

Hope this helps gentleman. Be safe. Go mgtow.

Made the engine run smoother and quieter. Unfortunately did not go in as smoothly as I would have expected. Got it in, but required some adjusting.

still working on the engine so not sure on fit and function yet but the service was very fast and the product looks and feels like a great product.

performed and installed as the reviews indicated.
Noise reduction and increase in throttle response.
i have recommend this product to others.
thanks

Noticed significant noise reduction in the cab at freeway speeds. Better throttle response, quiet enough to hear the S&B intake whistle

Made my OBS 7.3 run smoother. would buy again. Had to apply a couple of minor bends, no big deal. Great product!!
