fast intentions exhaust questions

Thanks Guys, I appreciate your input! Also plan to install low restriction intakes. I'll probably go with the shorties,won't they be better for the lower R.P.M. range? I would think the long tube intakes require higher R.P.M.s, you know, intake air inertia and stuff like that.

Nope, go with long tube, short ram is worthless in this car. Engine bay gets hot enough, you do not want to pull more hot air into it, get those filters away from the engine. Other option if you want to keep stock boxes is to look at Modshack and his DIY he did. Basically replace filter, silicone tube to replace piping, and ducts to bring in more cold air.

Also, the heat shielding on the Z, in many places, is just them covering themselves. Think of it as liability insurance, if something does go wrong they are covered, but aftermarket systems run cooler and more efficient.

But doesn't the whole nose have to be removed just to clean / replace the filters? I think that would be at least twice a year, and a couple of hours.

Yes the bumper has to come off, and no it is not twice a year.
K&N filters are good for 50,000 miles before a recharge is needed and then another 50,000 when you replace them or recharge them again. Recharge is cleaning/re-oiling them.

Also, bumper removal is around 10-15 minutes after the first time and you learn where all the clips & bolts are. We have taken mine off twice now and it is extremely easy, hardest part is getting the bolt in the wheel well area but that is a breeze now since we know where to look.

Well, doesn't seem as difficult as I'd imagined. Things are looking better, I'm sure I'll be pleased with the results, both performance and sound.Is it my imagination, or does the 350z and G35 ('08 and earlier) actually sound better?
