yea, ebay piping with name brand filter is just fine. a name brand piping and filter is going to be better of course, but not enough to notice a difference or for there to be much difference.
some places though, like California, require the whole thing to be a name brand with CARB approval and/or smog approval.


For the intake manifold, it all depends on what route he's going. If he wants to turbo, i'd skip the header, intake and intake manifold (which besides the intake manifold would be replaced and save for turbo parts instead). If he's going N/A or has extra money available, then yea an intake manifold would be a good idea.

 

So you're saying if you're just doing a new intake, not turbo/super, then it'd be wise to replace the manifold?
And generally if you're gonna replace the exhaust, a catback will come with a new header (even though header's before the cat), or you would probably buy a new header while replacing the rest of the exhaust anyway

You tried to clear it up, but I think I'm misreading it or something. Obviously Kurtzmann has a better grip on this than I do =p

 

If you're doing an N/A setup you should definitely eventually get a better intake manifold.

If you're turboing, then a new intake manifold isn't really a priority because your focus should be on the turbo setup. However, if you're trying to make as much power as possible or you have enough money to buy one and you want to buy one, then you should.


Superchargers don't apply to any of this reasoning because the supercharger is an intake manifold, with a compressor in it.

 

Really? would they find out if you dont have one on an emissions test, cause when i watched them do the smog test, I dont remeber them opening the hood, although it was about 6 months ago, so I could be completely wrong.

 

I'm not exactly sure. I just know that they have to be CARB exempt or CARB approved.

 

I think ill stick with magna flow.Im not really up for spending a lot of money on my car only because i cant afford to lol.Just to keep it sounding clean and looking nice. But i do want to put a good set of headers and complete new exhaust on it and then everything will pretty much be perfect for me.

 

idk how you're gonna put a set of headers on an inline engine
GL with that
