Stillen hfc vs f.i hfc

rz34 · 04-10-2011, 07:24 AM

Hey guys
i require your assistance i know that tony's products are excellent quality and have showen awesome results. i am just about to purchase their HFCs then i saw the stillen HFCs and on their website it shows a dyno of the hfc producing GREAT RESULTS on their own. i was wondering if anyone in this forum has done a dyno confirming their numbers as they are quite high as im unable to find a thread reviewing the STILLEN cats.

would any1 know how the stillen cats compare to the F.I HFCs in terms of POWER gains and SOUND??

your help would be much appreciated guys!

Sorry dude, I clicked before I really read the thread title. There are a variety of Cat-Pipes" or HFC going around, but if I had to stick to either Stillen or Fast Intentions, I would choose Fast Intentions purely on customer service. I have the TDX cat-back and ordered Long Tube Headers.

You should also consider the other HFC / test pipes out there and surprisingly, a lot of people have the other brands. There are a lot of videos on youtube, but all you gotta do is search a bit. Also try searching google to find stuff in the forum (I have had better luck with that than using the forum search feature).

And Welcome............
