ok, so i DO NOT have a full exhaust.. i have headers to a 3 in. pipe following is a 18in. bullet then off to the side, thats it... if i were to put an electric cutout right after the Y pipe would it help with any sort of way with back pressure, etc. if i were to spray 175? any help is greatly appreciated. thanx.

 

what motor is it? on a 6.0 definently but on a little 4.8 you probably wont see much difference.

 

5.3....
