CNT HFC's + FI non resonated exhaust
 

Looking to pic up the CNT cats but can someone please tell me if this combo will make me raspy?

Yes, very much so.

Gonna sound like a baseball card stuck in your spokes

Contrary to what some think, it should not have too much rasp! The CNT HFC's will obviously provide more back pressure than resonated or straight test pipes. This will help keep the rasp down. Rasp is a lot like drone. They are both subjective to the ear and what does to one person may not to the other!

With that being said, if you add resonators to your x pipe this will help smoothen out your exhaust note. It will also create more depth and fullness to your exhaust note!

Call me if you have any questions.

Thanks, Tony

I have the CNT with FI 18 Resonated, and I have very little rasp if any. Like Tony said the x pipe smooths the sound out.

what about getting the FI resonated cats? Will that have a similar effect as having resonators in the x-pipe?

i had 12" resonators with Berk HFCs and there was rasp. I would go with 18's if you wanna get HFCs

ahh such a bummer. I don't really want to make any changes to my catback. Does anybody have the FI resonated HFC's with the FI non-resonated exaust?

I am trying to decide between the new resonated ARK HFC's and the FI resonated HFC's. If the FI ones have already been proven to eliminate rasp then I will get those for sure. Otherwise I guess I have to take a risk and hope that the ARK cats can live up to what ARK has promised

What about ART test pipes? Supposedly they eliminate rasp better than hfc

I would love to get test pipes but I have to get yearly emissions testing where I live. Plus I am scared of what will happen when the Fuzz smell the fumes and pull me over

BTW I live in the Atlanta area and have asked for input from other Atlanta members about this before but never feel like I have gotten a good answer. If anyone can chime in about how the get away with having no cats please let me know or send a PM if you would rather do that. Thanks!

I don't have any rasp even when cold with my Berk HFCs and FI 12" resonated exhaust. Here's a sound clip:

I don't think its the cbe, its the hfc. I have invidia cbe and have a rasp/hiss during deceleration. Nothing major, I say just go for it.

That is a very clean sound, I like it. I just wish I knew if I would sound that clean without resonators.

Which HFC's do you have?

If you are going to ZDayZ, there may be the combination of exhaust components that have what you are looking for before you plunk down any cash! I just installed the Berk CBE and I want to get the Berk HFC's but I want to hear what the final product sounds like. I've heard a ton of different ones on YouTube, but there is enough difference to hearing them in person that makes me want to wait. However, I may not have the patience to wait until ZDayZ is over before I get the HFC's :drool: :drool:!!! Patience is not one of my strong virtues when it comes to the Z.

BUMP! Does anybody have the FI resonated HFC + FI non-resonated catback combo?

I have F.I. non-resonated Testpipes and non-resonated F.I. catback exhaust. I have some rasp during deceleration but honestly i dont mind it for how loud it is...I dont think i would take any setup over what i have. It's insanely loud and it has almost an exotic note to it.

Hey thanks for posting.

Just curious: where in GA are you located? Do you have to get emissions testing in your area? If yes, how do you pass emmissions with your test pipes? Please feel free to send me a PM if you don't wanna post it here.


To get back on topic: You are saying that you don't have any rasp when accelerating? Only when decelerating? I am sure it is loud but it's not loud in Civic-loud type of way is it?

CNT HFC + Invidia. And there is only a hiss on deceleration. It isn't that bad, but its there.

I live in Savannah and no i dont get emissions tested...If i did i would just toss my stock cats on, do the test and then put my test pipes back on. No its not civic loud at all, a lot deeper and it has a g35 tone to it but a lot louder...Video clips dont do it justice
