Best Sounding HFC with Stock Exhaust?

Which one do you think sounds best with stock exhaust for my 06 g coupe?

I've heard some people say to not even do HFC with stock exhaust because it sounds bad, is that true?

I've been looking at Berk or Kinetix...

Thanks

Would it sound good if I just replaced the Cats and nothing else?

You don't really buy HFCs for power...most HFC or test pipe = what 5whp at best lol

You get them to open up the flow of the exhaust better and still retain street legal driving & being able to pass emissions.

When you venture into the world of FI thats when opening up the exhaust becomes more important for gains.

That same 5whp gain on an NA vehicle (like your stock G) can = 40 or so whp on an FI (Forced Infuction) G by going from OEM cats to HFC, test pipes or straight pipes.

Iso plenum spacers on the other hand actually = some of the biggest bang for your buck gains our cars can get. I would start there first then venture into other mods.

Many of us did the same thing with our Gs when we started out

tiguy, i do know the plenum and spacer are the best bang for the buck and im definitely getting those....

im just looking more for an added sound from the car thats why Im looking for HFC first, and i know its not as much gains as the plenum and spacer but it is still a little gain plus itll make the car sound badass

Fast Intentions HFC's. It'll make it sound better/deeper, and give you better performance.

What other pipes are better than ART pipes, aside from long tube headers (which are totally impractical for the average G driver)?
