Im thinking about getting one. Ive heard mixed opinions about them though.

I wanna know if the people that have them like them. What type of difference does it make. Tourqe, hp, sound??...

Thanks

 

They don't work on hemis.

 

What he said. They only help on TBI set-ups where the injectors are in the throttlebody.

They usually do make an annoying whistling sound though

 

they give you 500 horsepower, no lie.

 

I heard they make your truck invisible to the PoPo's......

 

One cool paper weight

 

Only if you get the on'es with the swirl design on the inside

 

i just sold mine. it whistled everyone thought i had a belt going bad. cant tell a difference without it except the whistle. they advertise gains so i guess if you bought on and did not get any you could call bs on them. i should have done my hyperpac dyno before and after

 

Well, I was going to give my opinion on this subjest but i think it has been pretty much wrapped up! They are junk!!

 

There have been many dynos by 3rd parties. This is how everyone knows they are useless.

I NEVER go by what the manufacturer says as far as dyno numbers as the law isn't strict enough to stop them from falsley advertising. If you've ever seen their asds, they say gains UP TO xxhp. While this could be true, doesn't mean that YOUR specific vehicle will see those gains. Heck, even the JBA website has it going on for the Ram page on shorty headers. I searched for 3rd party results which I did find and they didn't match what JBA had said either!!!
