how big are the stockton ej1 exhaust pipping??? i went to the muffler shop they said i should go about 2 1/4 not 2 1/2 because my motor is stock with bolt ons and 2 1/2 would make my car lose power...what do you guys suggest???

 

if you dont intend on boosting or digging into the internals 2.25'' is perfectly fine

 

kool thanks...boosting future setup
