Thanks for the great review, SRG. The comparison vids were especially helpful! I, like you, absolutely love what they do with the stock exhaust. Sounds fantastic.

 

It sound amazing with HFC and stock. Now i need to heard HFC and ARK exhaust. Anyone has a video? i'm thinking whether i should just get the HFC like OP and keep the stock exhaust or go all the way HFC and ARK exhaust. Which one will give me more performance boost?

 

Just go with the ARK, bro. The HFC's will make you loose torque at low-end RPM's. Besides, the ARK sounds perfect on its own. And if you're looking for a daily/regular driving performance boost, the HFC's won't do much but sound. Unless, that is, you're wanting more power at higher RPM's. Just my 2 cents.

 

+1 for more vids. As it stands it has too much rasp in my opinion, but I'm sure it'll sound better after a few miles.

 

Solidtude it's the other way around. Lol your cats are the most restrictive part of your exhaust system.

 

Might be most restrictive (although Y pipe is not great) but it's proven you do lose low end to gain high end.

 

That does sound mean!

 

Not any raspier than stock. Just Amplified! No other hi-flow cat will be less raspier. Can't go wrong with Berks if you want to retain the famous G tone! And if you want a new cat-back exhaust to go with it that retains the g note would be the FI exhaust. Tanabee will change the tone completely.

 

+1 Yes! I still hear the lovely, natural G sound through my exhaust. Only it sounds grown-up and a lot tougher.

 

Thanks guys... Here's another video I took... It does sound raspy but when driving it really doesn't sound like that. I'll actually take a video with the camera recording the exhaust while I'm driving.

Xcalibur, not sure what you're listening to but there is definately an added rasp w/ the HFC's. I will agree though that it is more amplified and sounds great for the most part.

SRG, instead of taking a video from inside the car, I think it would be best if you can have someone take a vid outside the car as you go by WOT? In my opinion, it's pointless to capture the sound inside because your "audience" is outside your car who will be listening to it.

 

Raspy or not raspy, that sounds amazing! I like it a lot.

 

Sounds good to me.. stock has a rasp too.. can't wait to get mines installed on my sedan!!!

 

I told you.. you'll like em! Congrats buddy.

 

so which one is the correct answer???

HFC + Stock Exhaust

or

HFC + ARK

Which one will give me more performance boost after RevUP?

Thanks
