I have not done them since I have not bought my car yet, but my research shows that an axleback exhaust system and an intake will give the car more power.

For smog purposes though, you'd have to take the intake off since it's not C.A.R.B approved.

Smog Test's are every 5-6 years for new cars sold in Cali.. ;)

If your going to make a statement like that, then you might as well know that there AREN'T any C.A.R.B approved aftermarket exhausts or intakes for the IS-F :eek:

Joe, I really respect you and your company, however I lived in CA for 17 years now and owned 3 modded cars. I come from a car that is heavily enforced upon when it comes to smog (WRX STI).


The 6 year role is correct (6, not 5), however once the car is sold to the second owner (which would be me, since I'm not buying a new one), the 6 role no longer applies and you have to smog the car every 2 years from there on. Trust me, I've owned 3 modded cars in CA.

I check the K&N website weekly to see when these clowns will finally get the intake C.A.R.B approved, but so far it doesn't look like it's happening.

Please tell me something I don't know.

Cheers,

P.

Thanks P.

My response was to your original post....

You probably won't ever see CARB approved intakes for such a low volume car.

What you stated was: "Won't pass smog without the 2 rear cats. I wouldn't do this on a CA car."

Right now there is not one CARB approved product for the IS-F.

So basically we shouldn't ever mod our IS-F's in Cali :confused:

With that in mind, any intake or exhaust installed on an F can fail a Visual Smog Test in CA and in most strict States..

I can tell you right now our exhuast easily passes a sniffer test with out the 2 secondary cats in place.. Along with the basic OBDII test, since no CEL lights are thrown on.

In your case, you should mod away with your IS-F..
Then you just slap the stock intake back on for the biennial smog test..


We are all just here to share information :)

I think we are on the same page Joe. And yes, I will be modding my IS-F.

I will be modding cars until my last day on the planet.

Real quick, how loud is your street exhaust compared to Borla? Sorry, can't tell from Youtube videos....

Regards,

P.

I made some phone calls today, to see where is the IS-F intake market is headed.

K&N was not really clear on wherever they are going to make this intake C.A.R.B legal and make it for other years.

AEM was much more helpful on the phone and also sent me to this link where I can register for updates for products of my vehicle. The Rep said the IS-F is on the list, but the C.A.R.B part is another ballgame and may take a little while.

Here is the link, if we can generate enough interest, it will help:
