If you want the quickest way to get exhaust out of the engine, you can't get much quicker than running a hood stack. With Grand Rock's complete kit including mounting hardware and stack, you'll have the most complete kit on the market.
Grand Rock has taken what used to be a difficult task of building your own mounting ring and stack and developed this kit. They are available in 5", 6", and 7" diameter, all featuring a 20" length, as well as in chrome or raw, and finally with a flat top or mitre / angle cut. This is a universal set up, therefore there is no turbo pipe. Depending on what turbo set-up you are running the turbo pipe will have to be fabricated. These kits come with everything you need to install except the piping to connect to the turbo.
IMPORTANT NOTE: The hood stack kit is engineered and intended for competition or off road use ONLY, and not for use on street or passenger vehicles.

Does the hood stack come with the mounting bracket too or just rhe stack??
The mounting kit is included yes.
Is it legal in Oregon/ does it stil have the emissions on it?
This is a hood stack, this would be for offroad, race, or sled pull applications only.
Do you fabricate the pipe from the turbo? What would that normally run??
We do not fabricate that part no. Not sure what it would normally cost, get 3 quotes though. SA
So for the 5 inch hood stack kit. How big will the hole in the hood have to be??
We would recommend getting the kit and using the mounting ring for a guide to mark out the hole. It ends up being about a 5.5 diameter hole if I remember correct. But wait for the mounting ring and use that for reference. -Sands
