im right behind ya, #622!!

Haha. It really isn't as bad as people make it out to be.

i disagree. stock CBE came off in 5 min. cats took over 2 hours to get off. install of new TP and CBE took 10 min.

If you go into it having all the necessary tools, it's a breeze. It was for me, at least. The demon bolts just snapped off as soon as I started twisting them.

i was in a full garage/fab shop my buddy owns with any tool imaginable and it took 3 of us that long to get those 2 awful bolts to let go. i actually ended up slightly damaging the flange on my one of my cats because of it. damn you Nissan :shakes head:

You guys have me worried. Just got #612 after a short delay and will try install here in just a few hours. I'm worried about the cats :(

everyones seemed to have been different. most seem to have little to no problems. i may have just been unlucky. it shouldnt worry you. the only hard part is the tighter space to get in there when removing the cats.

please dont let my horror story of bad luck with my cats scare you. just sharing my experience.

24" of extensions and a universal joint for a 1/2" drive and a breaker bar (jack stand handle) and you'll be okay. Oh, and some PB Blaster.

Use a penetrating oil like Kroil or Pblaster on all 6 of the bolts and let it sit for at least an hour.

I actually let the bolts soak overnight with a coating of Kroil. I think it definitely helped as I got both demon bolts off undamaged!

I work at a Porsche dealership and one of the techs is going to help me :) Never hurts!

I am so tempted to go straight through i can just hear my boss in my head saying you idiot haha

The idea off scaring people is just to tempting.

Thanks I know what they are for however like it or not they still make some difference to the overall sound
There will be a difference between say a hfc and cbc vs a res hcf and 18" res cbe there is no way there wouldn't be a significant sound difference both inside and out.

I was simply asking what people preferred after hearing the the different combinations running, I am sure I am not the only one that’s a little indecisive at to what combination to go with.

Well i got the install done! maybe an hour and a half. The bolts sure were on there good!! I guess they dont use torque values lol. actually removed the intake tubes and got the demon bolts from the top with a long extension and bar, took maybe 10 minutes.

It is louder than i thought it would be with more drone than expected but its perfect!

I assume this is the hiss people here talk about? When i let off the throttle i hear a hiss almost like a rattle kinda.. put it in air and used my stethascope lol. Sound like its comming from the xpipe. Is this normal?? I would think its from scavenging and a vacum up at the front?

12" res and res hfc? you have exactly what ive ordered. im affraid its not going to be loud enough, tell me im wrong lol

never mind i see your post, louder then you expected? awesome then i should be happy hahaha!

Man, time flies. Just received shipping confirmation! Tony was bang on with his estimation, ordered around September 1st or so.

18" res w/carbon fiber.

I just have HFCs and I get the rattle when I let off the throttle, too; I characterize it as a rattle as well as opposed to a rasp or hiss. I only notice it when the car is cold.

A rattle and a hiss are completely different sounds though. If it's rattling, then maybe you should get it checked out lol.

What number were you?

I *think* I was #620.

That works for me! Im 621

there has been many times i come to a stop sign or red light and make people jump. i still get a kick out of seeing younger kids heads whip around for a second look whenever i get on the gas lol they always look at the car but at idle the exhaust is very tame even with the TPs like mine.

^^^^^cant wait to get mine....sigh.

we all had to go through the long wait. i'm just sad that my Z is getting park in the next couple days then it'll be a few months til i get to hear that amazing sound again :shakes head:

#621. Just got my shipping info :)

hey man a few months isnt that bad... trust me. haha trust me though guys it IS worth the wait

X2 :iagree:

Can't wait to receive mine! Just placed my order for a non res cf with non res hfcs, #677. (:

This is what a FI exhaust has in store for you all :)

Mine ships today! :eekdance: :eekdance: :eekdance: :excited: :excited: :excited:

Buy ear plugs.:tup:
That will be one loud motha

Didn't I tell you before that you're neighbors will love you :tiphat: I know exactly what you mean. My kid's know daddy's coming home.

Haha same with my dog. I've had mine for so long I'm used to the volume but I still want it louder

I need to not read this thread, the wait is killing me. Especially since when I get it I'll have to wait until spring for the install.

Maybe just staring longingly at the uninstalled exhaust will provide some comfort.

test pipes or hfcs i cant decide??!!!!

i love the TP just my :twocents:

Watch the dyno video on the F.I website. There's a noticable difference

They only have a dyno for hfc not test pipes

The first part of the video is resonated TP's. Well, exhaust w/ stock cats. Then exhaust with res. TP's and then exhaust with f.i hfc's

If you're worried about sound then watch the video and compare. If you want moar power, i believe the TP's make a couple moar whp.

Any 630's get shipped yet?
