Fast Intentions Resonated HFCs info?

ArtVandaleigh · 09-01-2011, 02:44 PM

I have a set I've used for about 5K miles that im putting up for sale shortly. Ran them with the FI 18" resonated exhaust. They are fantastic cats, and did cut down a lot on drone + smoothed out the sound over non-resonated Berks. I noticed no power changes over non-resonated HFC's. If you have any q's or are possibly interested, PM me.

Will an exhaust and HFCs improve my throttle response?

You will see a big increase in throttle response throughout the entire RPM range. This combination will yield over 25-28 RWH & over 20 FT LBS of torque.

Did you get my response to your PM's? Anytime you want, please do not hesitate to call me...

Thanks, Tony

Yeah, I called you the other day already. Thanks for the info. I am looking over my finances now and thinking about it.

I just have test pipes and my throttle response has been soooooo much better so I can't imagine with the rest of the exhaust system.

One of the things people tell me about the headers is they are suprised at how fast the engine revs. Really high, really quick. But not ridiculously loud. Just clean.

I heard they were quite loud. It doesn't matter though... for emissions there is just no way I could ever do something like that without massive work every 2 years

I recently was curious about a 200 vs. 300 cell count on HFC's. Ended up reading that the difference between them is so minimal, its almost pointless to compare...

Tony told me that with an automatic, there will be some drone with the exhaust and HFCs. Anyone out there with these and an auto who can chime in with how much drone there is?
