Will a DC header decrease the low end HP ? I have read some of the other threads and have noticed that some say " it will decrease the low end HP" and others say " it will increase HP across the board".. Can someone please chime in that has a DC header. Also, what did it do for Gas Mileage - Increase/Decrease ? Is the juice worth the squeeze ??

I will be leaving the exhaust as is - and i'm going to leave the KN air filter in the factory box.

Thanks !

 

It wont decrease your mpg and if it were to decrease any hp it would be nothing you would notice and make up for it with the increase you gain as thr rpms increase.
