Marty if there saying that with only a pipe. its a lie.
not with out other things like a full ECU change and a proper
map set up on the injection. and possably and air intake rework.
See thats where thay get you.....
you can get gains like that. but you got to have all the components
to make it work.
Horse power is made by how much air and fuel you can push in and
out of the motor. all the air moveing out means nothing. if you ant getting
more in. and you need more fuel.
I wish thay would just tell it like it is sometimes.
i just read an artical the other day that told how much power
the new muzzy exacust will give a tyrex. but you should see all the other
things you need to go along with it or its almost useless.
That would be like me saying if i put flow masters on your mustang
you would see an 8% total gross HP.....
and thats something that acualy has a little power not 40 or 50.
i dont buy it. its Bull ....
