Which exhaust is better?

 

question is too broad. be specific with what your asking.

in what respect are you evaluating the exhausts

 

They are completely diff exhausts, the Injen SES is a header-back which will add some performance for sure(not sure how much, a few hp though) and has the "grenade launcher" style. The GReddy SE is an axle-back which will have ZERO performance gain and is only designed for looks/sound. The SE also has a more stock look to it except for the ti tip.

 

INJEN ALL THE WAY MAN.......... More Performance
