STILLEN HFC Installed Video

[suby01]

my 07 g35x with stillen intake and stillen high flow cats video of some revs and drive byes. enjoy.

[snwbrdr435]

sounds good suby, i bet it sounds 10times better in real life tho.

[joe603]

Sounds great! You don't have a Stillen CAT-back??

[TeflonG35]

Sexy sex.

[suby01]

Sounds great! You don't have a Stillen CAT-back??

nope completely stock exhaust setup all i did was switch out the two cat converters.

[tollboothwilley]

Sounds great. Did you notice a big difference with the Cats?

I've heard good things about swapping them out.

[suby01]

actually i didnt notice any gains myself. unlike with the intake i felt the rmps reach redline a bit higher at highway speeds. but for the HFC i only notice the awesome sound. i do know that others got a dyno right after they installed it and just the cats gave out 8 whp. so i should of got just about that.

[RED_DET]

Hard to tell from the video, any obnoxious drone coming from the exhaust inside the cabin?

[suby01]

nope at all.

[G_whizz]

Yup sounds mean!!

Exhaust next??

[suby01]

Yup sounds mean!!

Exhaust next??

you keep doing this to me. and everytime i say noo. but in the long run i end up doing it anyway.

[TeflonG35]

They compliment each other.

[Triton3.5]

hey Suby,, I think it sounds real good,, like you i kinda like my stock exhaust sound,, but have been contemplating test pipes, OR HFC's also thanks for showing what ya did!!

[tollboothwilley]

I love the sound of the HFC's

The COBB tuner is supposed to work really well if you have change these out, just so you know

[TeflonG35]

Cobb tuning is still neglecting the 03 sedan

[tollboothwilley]

have you talked to COBB??

I haven't talked to them in a few months now with work that I'm doing.

I know that the 03 was a different ECU and the code was much different. They were having to redo a lot of work for it but said it would only be another couple of weeks back in April/May.

[TeflonG35]

I sent them an e-mail back then. And they said something along those lines. I also just checked their site and it still has the disclaimer for early model sedans.

[suby01]

no prob

[RShih]

With the HFC installed, does it pass inspection? Can you still use the stock O2 sensor without the ecu throwing a code?

[suby01]

will pass inspection and no code had it for 2 months and i jsut got a check engine. i dont know if its the o2. catalyst threshold below efficency.

[Gdubya35]

Sounds tight. Have to keep that in mind when the time comes for mines.

[4drmadness]

hey man, im looking for stillen HFC'S my self for a 04 sedan. your car sounds great. hows the HFC treating you right now? 02 sensor codes? any other problems with them? deos it pass smog test as well?

[suby01]

its sounds awesome i do have a mass flow code now. after like 3 months of driving. im still waiting on a response back from stillen. but def more power and sound is sexy. just ticked out the engin light on the dash.

[4drmadness]

oh ic see, so are you planning to just clear the code or just take the HFC off or just live with the code? let me know.

[tollboothwilley]

if it doesn't fix itsself, he'll probably get anti foulers

thats what most people use with test pipes

[4drmadness]

oh i see. those CEL fixes huh

[suby01]

ya im deff keeping them. just looking to get some kind of way to change out the sensors.

[4drmadness]

i just got mine installed. i love the sound, and i can feel some gains as well. def a keeper. i didnt get the cel light, so hopefully it never comes on. ill get some vids up soon

[tollboothwilley]

CEL probably wouldn't come on right away unless you installed correctly. I think it was about 3 weeks for Suby when he started getting the light...but it came on and off if IIRC.

[4drmadness]

hey let me know when you change the sensors so i can do it to when my CEL light comes on. until then im gona FLY
