Is it pointless to get a HFC if you want to leave the exhaust stock? I've had exhaust on all of my previous cars, but may leave it stock for a while.

My intention is just to keep the car quiet at the lower rpm's but a bit louder from the engine/exhaust at WOT.

Thanks

 

HFC will give you decent HP gains even with stock exhaust, it will be louder a bit louder though for sure.

 

Louder and slightly raspier. The gains will be at the top end.

 

Thanks guys. Any way around the raspy-ness?

 

Yeah. Add a catback exhaust. Heh. It won't be too bad with the stock exhaust though.

 

Hmm, I tried searching for vids here and youtube but nothing much to listen to. A few that claimed to have stock exhaust, but I am pretty sure it's not stock because it sounds really loud.

 

No, there's no way around it. That's the nature if HFC.

 

I had it (Berk HFC) on stock exhaust and it enhanced the stock sound dramatically. The rasp was not bad at all. I say all for it!

 

Go for it man!!! I have on FI hfc's currently with the stock exhaust, and love the way it sounds. Slightly louder and deeper, but not too much. My G feels like it pulls a bit harder off a dead stop, but can tell a huge improvement at highway speeds. Saving up for the FI catback now

 

^ Do you guys have any soundclips or can make one?

 

It's not much, but it's something...

^That first link I saw lastnight and the "stock exhaust" doesnt sound stock does it? I haven't rev'd mine like that yet, but it just doesn't sound stock. Then the 2nd part sounds like exhaust. If that's REALLY just the Berk's HFC's, I'm pretty impressed and sounds like that's all I really need.

The second link sounds pretty nice also. Since he is basically WOT the whole time, does anyone know how these sound between 1-4k rpm?

 

Also another question that comes to mind. I know an exhaust shop that does very good mandrel bent piping work. He has done custom made downpipes and catback exhausts for me in the past.

In hopes of saving some money, do you think it would sound the same if this shop basically replicates this HFC? Or would it sound different?

 

just cut the exhaust off completely after the headers...should sound close to stock but a bit louder and cheaper too

 

No offense, but that's ghetto.
