What hfc's don't have that rasp?

[dbass]

I'm possibly looking at getting some but not sure if I want the rasp really, are there any I can buy that don't rasp?

The ARK designed HFC's with the extra canister are supposed to reduce the rasp.

Daryl just had some Invidia HFCs and he says there is less rasp. You will still get the "hiss" though.

thanks chaps

I had Rasp from my Berks & hated it.

Fast Intentions in the US do 'resonated' HFC's.

Tarmac imported some for my 370 at my request. In short.....:they are b####y FANTASTIC.

Rasp.......eliminated completely!

So there....... It can be done guys :-) :-)

Motordyne ART are fine... bit pricey though.

Yes cheers dbass....

Those are the babys. £ well spent :-)

I have read that (and although makes no sense to me) on some of the US sites that if you heat wrap tape them it will eliminate rasp, its no bad thing either, keeping the exhaust gases hotter means a quicker exit from the engine

Has anyone tried the Fast Intentions Resonated HFC on a 350Z? I'd be interested to hear a video with an Invidia Gemini exhaust.

I'm interested in the same.

 

I have the Invidia Gemini Cat-back exhaust on my 350Z -- and Want to throw on something JUST for some power before my Tune,.. and was recommended Berk HFC's -- but the reports here say they are raspy.. So,.. what HFC's (or test pipes) will not make my Invidia Gemini (and exhaust in general) WAY louder than it is.. and won't change the smooth, zero rasp tone it has?

 

I've considered Test pipes like the ART's.. but I've also heard they cause a strong odor which will come into the cabin of the car (this true).. I see a bunch of people throw on Test pipes and then have them up for sell weeks or months after putting them on.. there's a reason for that.

 

I'm at a PERFECT sound now with this catback.. so I'd like something that is for power adding only (before I get my tune) that doesn't rasp period, and if it's going to do anything I can't avoid merely makes the exhaust just a tad bit louder (be nice if it didn't change anything.)

 

I'd rule test pipes BACK IN if they don't cause the odor. As the CEL I'll get turned off with the tune.

 

Thanks!

You need the ARK HFC's then. Thats what the resonator is for, to reduce the noise

+1 to Fast Intentions. I have those on mine and no rasp at all (which is handy as I'm not a lover of rasp either)
