PPE Boost Valve
 

Would I be able to put this on my truck it is stock. Would I notice anything?

yep you can put it on, probably wouldn't notice much though untill you get a tuner.

Ok thanks.What would make the turbo louder without buying another turbo?

I put a boost valve on mine stock and could not really tell that much of a difference maybe 1-1.5 psi maybe not really enough to tell though

ways of making your turbo louder are taking the resinator off of the intake, thats the thing on the top that says 6.6.
you can port the stock turbo horn to a bigger size that helped mine quite a bit.
straightpiping the exhaust helps some, but the biggest difference i did was got a metal intake from bills custom intakes, made the turbo sound like a jet lol.

yeah no problem puting it on stock

How much was the intake?

it was around $200-$250 don't remember, look up bills custom intakes. he has some good prices and you can get a turbo horn to go with it and make it scream lol.

I checked the turbo horn. How does that install?

not fun to be honest. i ported my stock one. they are a pain! if you get a 10mm gearwrench and a 1/4 inch 10mm wobley then it makes the job much easier. the bolt on the bottom is a pita!
i have heard that the new turbo horns he sells have a cutout for the bottom bolt so you can start it and then slide the horn over it. that would help a ton! i will be upgrading my stuff to one of his bigger intakes here someday lol with a turbo horn from him.
