hey guys i posted a clip of my stillen TD the other day. this is a clip of the Stillen with ultimate racing HFC's its a tad muffled at high RPM's so hopefully I'll get a better recording tomorrow. anyway here it is

BEFORE: http://75.176.94.208/stillen.mp3

AFTER: http://75.176.94.208/stillen+hfc's.mp3

let me know if it works or not

 

ok I got up a little better of a clip but this is seriously the last one I can do tonight... The old lady next door is going to call the Friggin cops if I don't cut this **** out.

 

It sounds nice, do you have pics of the stillen on your Z by any chance

 

nah i will try to post some up later tonight

 

it works and sounds great. what a differnce the HFC's make!
i'd liek to see some pictures too.
if you dont mind me asking how much did you pay for your exhaust set up.
congrats on the purchase and the awsome sounding exhaust

 

any drone or anything while cruising? How much louder than stock is it while driving normal?

 

Sounds great! You're mods are coming along nicely daniel, and pretty fast I would add.

A little OT, were you able to find the seats that you wanted?

 

There is no drone. while cruising. Barely even audible. I paid 1250 shipped for the stillen and 550 shipped for the hfc's

 

yikes....a bit too much money unless you got expedited shipped

great cats though....3 years now on my car they work great, fit great and I'm even going to swap them onto phase 2 of my car

 

stillen exhaust sounsd sexy.

 

thanx. I have figured out though that, especially when its cold, the car buzzes between 3-5k rpm when under load (not when idling free). I got the hfc's over the tp's cuz i thought there would be no rasp. I'm not sure if its even rasp that I'm hearing its more of a metallic sound. So just beware of that. If I can't get it taken care of I may have to take these cats off.

 

Yeah I recently went from test pipes to the UR HFC's (on adam's recommendation btw). My goal was to quiet the exhaust down and clean up some of the rasp. The exhaust sounds great now, but still just a tiny bit of that rasp, but it's so much better than it was, I'm very happy with it. So mine sounds a lot like yours does when you come off the gas, maybe a little less rasp on mine. Although your stillen exhaust seems to retain more of that "Z" sound compared to my Borla TD.

Is that a single or a dual setup?

 

its a dual. did you have resonated test pipes or just regular ones. I think I went off adam also. is he the one that did that right up?
