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

 

Berk bro, if you can find a used one...

 

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

 

Also would I get the gains Im supposed to get from the HFC if i keep the rest of the exhaust stock?

 

Plenum Spacer>Ztube>Berk HFC

 

Already got my stock airbox with ztube...

Kind of looking for a big sound upgrade, ill definitely do the plenum spacer after this...

 

ooh... Then go Test pipes bro..then ur good to go..lol

 

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

 

Wat he said ^ plenum first berk if u got the dough but either way those will surely improve the sound u seek

 

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

 

thats what i did...z tube/k+n drop in first...then the Mrev2 and spacer...then had to lower it on tein 350z s techs and put spacers on cuz it was dying for it...and just recently put on Berk HFC's with completely stock exhaust...love the sound and just how much smoother the car runs/idles in general...you can tell it breathes better...worth it!

 

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

OR

MotorDyne ART Pipes for the best performance.

 

ART pipes?? i dunno man not the best out there but they are really good,berk is the way to go.. found some for 383 or 351 shipped at this page.

^ WATCH OUT, got a warning from that site that it sends you malware

 

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