If you had to pick something

If you had to pick a part for your Max to buy first, would it be an intake ( if so what kind and by who? ) or something for exaust ( if so what and by who? )
Thanks

Depends on how much money you're looking to spend, if you don't want to spend much money get an intake, maybe a stillen. But if you have a little more money I'd go for a Y-Pipe :)

or jus full exhaust, but if ya have the money get an intake and exhaust

or jus full exhaust, but if ya have the money get an intake and exhaust, that way one isnt killin the other

If I would have to spend 800 bucks at once I would get a performance exchaust and TURBOCHARGER. Hardcore style man. TURBOCHARGER is the next thing Im getting.:devil: :devil:

i would get the exhaust. if you get the intake you can easily get more air into your engine but it wont go out as fast as it should. if you get an exhaust it will even improve the air flow you have now. Be careful though because nissans are high compression engines, so if you take too much of the back pressure away, you will wind up LOOSING horsepower. i'd get a young mechanics opinion about the type and set up, one thats into racing himself.

I would get the intake first, contrary to un4gvnbb. Its harder for the engine to pull air into the engine than it is for the engine to push out air. If you think about it, the air is sucek in by vacuum when the piston moves down, but gets physically pushed out with the piston when it moves up.

As for backpressure, that's not what matters. It exhaust stream velocity that matters. If you have a tube of air moving at high velocity, it has a certain momentum. If you stop applying pressure to that tube of air, it will continue to move and create a slight vacuum and by the time the next valve opens, it aids in sucking out the exhaust from the cylinder. So its great to have negative backpressure. The problem with zero backpressure arises when you don't have any exhaust velocty and the exhaust is venting right to a non moving body of air. To illustrate what I'm saying, take a piece of 12 vinyl hose that is a few feet long and blow out. In the middle of that, stick your tongue in the tube and you will feel the vacuum. You can even do this with a drink and a straw, except with the drink, suck the drink up and then stick your tongue over the straw and it will feel like it still wants to keep flowing.

Remember... exhaust stream velocity, not backpressure is the critical element when modifying exhaust. Resistance to flow is ALWAYS bad, but you don't want too big of an exhaust or else there will be very little flow even though you have low backpressure.

Go to this link for more detailed info on exhausts. A Very good read.

if you're not buying the intake and exhaust at the same time you always get the intake first. exhausts sound kinda blah by themsleves and the intake is what gives the car the growling sound and the exhaust compliments it.
