Test pipes are known to provide a lot of horsepower with less money.
But will all the (resonated) test pipes not pass the smog test? i live in CA.
I heard by using test pipes, one's car could be taken away.
If not, then what brands sell (resonated) test pipes that passes the smog thest and no worry in one's car taken away??

thank you

 

1) Wrong forum

2) HFC's aren't legal in CA anymore, I'm sure the same applies for TP's.

 

idk which forum to post. Drivetrain?

HFC's aren't illegal because they still do the job of a CAT.....TP's will deff be illegal specially in CALI since they have crazy laws dealing with emissions. So having a TP consists of NOT having a CAT to clean the gases. So as i am not sure what they do to you or your car when caught but most likely it will be something BAD!!!!


Remember, FnF was only a movie...lol!
