I have the Injen SES exhuast & I've been seeing a lot of people talking about using test pipes in combination w/ their cat-cat exhuast systems. What exactly are they? Where would i get them? Price? Thanks in advance.

 

Rather then having a catalytic converter... you replace that with a straight pipe (with no resistance in it) so you then essentially have a free flowing exaust system...

There are a few places to get them.. Some group buys...

What is better to get are HIGH FLOW CATS... Then you dont have to worry about emissions which are strict in chicago...

From what I have seen so far Performance Nissan has the best High Flow cats to my knowledge...
