Headers and your dealership experience

So with a lot of us running aftermarket headers or soon to be (PPE group buy), what experiences have you had with the dealership and warranty issues? Was anyone bold enough to ask the dealer to install your headers?

Has anyone passed an emissions test with headers + stock exhaust?

Also, once the PPE headers are ready, I need a place in Detroit or Buffalo that can do a good install job since I doubt anyone in Toronto has experience with the car.

Thanks,

Carbon

I have sikky headers. No loss of warranties. I passed emissions. Can't speak for ppe but sikky headers are good to go.

Excellent! Those were my two biggest fears. You have an aftermarket exhaust too. Did you have cats welded in??

I run no cats. And yes I have an aftermarket exhaust. Just curious why did you choose ppe over sikky?

I'm super tempted to order the Sikky headers...I see no reason why this would effect the emissions test in CA. I just saw a video with Sikky + JoeZ exhaust...awesome!

2015 RC-F from 2008 IS-F...very happy

Is this normal or do our engines run exceptionally clean?

Getting in on the group buy was mostly the reason. I've seen PPE's work in the past and it was always quality stuff. It really is up in the air as to which header is the better product.

Can anyone recommend an installer close to the Buffalo, Detroit, or Toronto area?

In Maryland they plug into your ecu so as long as your good no CEL you'll pass unless you get someone who is a real jerk and wants you to hook up to the sniffer but that barely ever happens.

So guys, if you had headers , and the joeZ exhaust fitted, but had a cat fitted between the 2 sensors on each side, would u still need the O2 simulator? Or would I get a CEL light? I've heard the CEL light may even flash on due to increased gas flow..... ?
Thanks guys

^^^^I am running PPE headers with a Custom Dual Exhaust System. I am also running PPE Magnaflow cats right behind the headers and have no O2 simulator. The stock heaters & sensors are installed before and aft of the cats. I have had my the headers and cats installed since April 5. No CEL. See picts attached.
