when i look up the 2006 coupe mid pipe from infiniti parts they only show a intermediate pipe. is that the same thing? What is the hr-y pipe called in the factory parts list?

 

Intermediate pipe is the mid-pipe. As for they HR Y-pipe, i dont know

 

Can anyone tell me the difference between the plenum spacer and kinetix plenum and which one is better.

Also will I feel and hear the difference with the kinetix hfc's?

Thanks Guys!

 

You will hear a difference with the HFC. I just installed Berk HFC and i get more drone from my exhaust when im at idle. and it did make my exhaust a little deeper and louder when im on the throttle also, but i have an HKS exhaust. I dont really feel any real gains form it im might have gained a few HP but i drive like a grandma rite now because gas is so damn expensive.

 

Yeah thats all I really want is a deeper sound without spending too much money and not sounding like a honda.... Any suggestions? I found the Kinetix hfc's for $350

 

I heard Kinetix HFC are more raspy then the Berk but i never heard them in person. thats why i spent the extra money and got the Berks because i heard nothing but great things about them. I spent $410 for the berks shipped. but if you have a stock exhaust still you should be ok I dont think you will get much rasp.

 

Are there any easy rules around wheel size and drops with respect to rubbing? I have 19" wheels on my 04 Sedan...would dropping it another inch potentially cause issues?

 

Another!

I know my G has the Aero package, but I thought that the sport suspension package was only available on 05s and up, however, I know that I have the red struts which means sport...meaning what? My 05 and up info was wrong?

Also, does the sport suspension change the ride height or was it just stiffer than base?

 

^Yes, your "05 and up" info was wrong. I've seen plenty of 04's with the sport package. It even came with special wheels.

I'm not 100% sure... but I think I've seen an 03.0 with the sport pkg.

I believe your ride-height is the same as stock, just stiffer springs and different damping on the shocks.

 

You say "dropping it another inch" but aren't you still at OEM height?
If so, a one-inch drop should give you no problem at all.

If you're already lowered, you'll want to provide specs of what you're on now, fender to ground measurement, tire size, wheel offset and width.

 

Yes, sorry, there was no need for that "another"...it's at stock height.

Thanks.

God, I have so many questions...but I know how annoying it is to ask away when there is a plethora of information on this board...will review the suspension thread!

 

^Knock yourself out dude. That's really what this thread is for.

 

What mod gives a bit better gas mileage?

 

^The "right foot mod"

 

Lol I know that already learned the hard way.

But is there a mod though?? Cai, filter, something lol??
