I'm shocked
 

I have a similar situation. Can be discussed.

ill worry about that in 6 years (isnt it 6 years for a new vehicle in california?)

regardless..couldnt you just change the tune on the fly to the stock tune as per the UpRev allows, and hope the CEL doesnt go off during a smog?

or screw it..i know some places where i can pass smog :tiphat:

yes..GTM recently stated they have "cracked" VVEL. to what extent? they havent said. i believe theres a post in the forced induction thread somewhere

9,000 miles on my ERZ HFCs. No CEL after the initial one that was due to not tightening one of the o2 sensors. :)

These are 280 shipped now are they not? if so they really are a no brainer if you want HFC's ..
I ran there TP's a while back and had no complaints.

I just ordered mine!

I just installed mine this past weekend. The sound did not really increase. The exhaust is a little deeper but that is about it. The Nismo exhaust is still quiet.

Hoping for it to go back to $280 shipped.

what is the difference between the cnt resonated test pipes and the cnt high flow catted pipe? i wanna know why the resonated type is much more cheaper than the high flow catted type?

your compairing test pipes vs HFC the HFC are more expensive

but from the pictures,both of them look the same..

Test pipes don't have "packing" material...no bulged out part. The gases go straight through.

One is a test pipe, one is a high flow cat. :tiphat:

We are having a GB on these CNT HFC here is the link
