the Injen SES exhaust is supposed to be C.A.R.B. certified/pending certification. So, you should be able to pass California smog testing and visual inspections with the exhaust on the car. If I were to buy the exhaust, I would certainly hang onto the documentation "just in case" as it were.

 

how about canadiann buyers??

 

So it's been about a year since the last reply. Has anyone purchased this Exhaust? And is it worth it Performance wise because I am considering it? Thanks

 

Yeah it s worht it, I just put it on my car and it does make a bit of a difference. The throttle response is better at mid-high RPM, and it sounds great, not too loud.

 

Thanks Nicho

 

Also have it installed on my car, I love the sound but I do get stopped from time to time. Butt dyno would indicate a bit of hp increase but nothing drastic, definitely a lot smoother throughout the power band but I also have supporting mods.
