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

 

Nice G and it sounds mean!

 

sweeet video

 

nice. now all you need to do is eliminate the stock y-pipe. just have an exh. company cut off the pipe at the flanges and in front of the resonators, then replumb, turning it into duals.... that'll free up that last bit of resistance in the stock exh.

Also, I love how your running around, slammin the throttle here and there but your mileage display is on.... what's it showing driving around like that....

 

honestly, i'd be happy with the sedan just sounding like the coupe. but i'd hate for it to be too raspy [fart can] if you go overboard. this is borderline badass though! you kept the stock exhaust?

 

Very nice sound! very distinct from the common mods with the exhaust replacement. That definately sounds mean.

You hear more of the engine sound too rather than exhaust. Very nice.

 

Sounds Not Bad! I really want to Install these or any other HFC! But I hear so much guy's getting the CEL, because they broke the 02 sensor upon installing the HFC's! I read that there is one bolt up top that is a real PITA to get too. And with the 02 sensors being so prone to breakage. it is what is stopping me from Installing the HFC! And I don't really want to spens $300-400 Having someone else to do it, while I can get it myself? I'm stuck, LOL

 

Sounds great!

 

how much are the stillen exhaust go for anyone can help me out with installation. Stillen HFC installed? from so cal. great video of the demo suby01

 

suby, how much did the sound change inside the vehicle, cruising around normally? can you hear the intake ALL the time or only at higher rpms under heavy throttle?

 

I would imagine with that rasp it may be a bit louder in cabin...

Nice work suby01! (you were the one to inspire me to get springs for the AWD, now you're tempting me to get an exhaust!!)

 

thanks everyone. ya i dont really feel any power gain from it. but the sound is amazing at under 4K def not raaspy. honestly none of my friends have noticed it yet until i told them then their like ooo yea its a bit deeper. but there is a G meet this Sun in CT. so im gonna see what their initial reaction is and if they will notice it. ill let you guys know.

with my driving style i get 13.2 mpg. and the high throttle was for video purposes only i swear

the sound inside car doesnt really change defiantly with the windows up no matter with high or low throttle. with the windows open as you heard its only when giving it light gas and i think it sounds soo sweet if your concerned about sound change inside the car the HCF is def not affecting anything.

yes everything else is completely stock, all i did was switch out the two cat converters.

yes the intake kicks in at 4K rpm so cant hear the exhaust unless your like driving behind me with the windows down they you can hear the gurgle.
