You don't need longtubes for FI. You have answers to all of your previous questions already.

You dont need a lot of things, but it is recommended. I'm sorry I didn't realize you were shutting down the discussion of this thread hahaha

The rotten egg smell is from cars that have cats,u dont get that smell when running no cats.Most states even when the rear 02,s are turned off can tell when u have no cats or a cat problem because the 02 moniter will not complete a drive cycle,if so that is a automatic fail even if the cel is not on.I have no cats,put the mak delete pipes on but will have to put my stock mid pipes back on to pass emissions.

Tommy, you are right. I just remembered that my WRX had 3 cats. Two in the downpipe that I removed when I replaced that pipe and one in the uppipe (pre-turbo) that I was unaware of for a few months (because 3 cats in a single exhaust system with one being pre-turbo makes no sense). My later version of that car got rid of this, and on my STI replaced that pipe anyway (don't remember if it also had a cat in it) to put on a up pipe with a port for an external wastegate.

So when I was experiencing that egg smell, it was the poisoning of that single cat.

Yea i dont know what it is in those cats but they can sometimes really have a bad rotten egg smell,really sucks when ur on a new date and u get into the throttle and she starts looking like what the hell is that smell lol.

Actually if your car is 2000 and newer you no longer have to pass a sniff test they just plug into your computer and make sure everything is running ok. You just have to find someone to look past the visual test ; ). Plus like you said no testing for 5 years that's why I got my catless headers on so I can enjoy them without having to worry about finding someone to "help me out" with smog visual.

Much harder to find "help" these days; Nazis are cracking down on the techs and they are running scared. I had passed several times with a BBK CAI and Morflow cats (88 GT) but time before last I ended up at the smog refereee over the cats (they finally found the exemption order on line. I had printed it for them but that wasn't good enough) and the very last time they failed me because my BBK CAI didn't have an EO sticker. Not that a CAI does anything, and not that the BBK doesn't have an EO, it does. But they started requiring stickers in 2013, which didn't do much for my 2007 CAI. What a pain in the rear.

Does anybody know if running high flow cats raises the cylinder head temperature a lot higher than without the cats?

 

[Grimace427]

I haven't seen anything that suggests the two are related.

I have a full Kooks exhaust with hi flow catted H-pipe, sounds amazing, still have a fuel/exhaust smell in my garage. Going to try catless, mostly for security purposes and hoping to pick up a few mph, but will go back to my catted pipe if it drones or smells terrible.

Headers will certainly help you get more out of your FI setup, but in all the FI threads I have read here, I don't recall anyone suggesting that headers are something you really should do if you go FI.

If FI was on the table for me, I would specifically not get headers due to the added cost (both parts and install) and the fact FI without headers makes plenty of power.

I was just curious because of the restriction, I can't see it being too terribly high.

This was from another FI thread

"Don't forget headers. You're more than likely going to get a custom tune and no point getting a tune without headers to squeeze out that extra HP."

There is no context in what you have quoted.

The discussion at hand is whether headers are suggested/necessary when running FI, not should you tune or not.

Is he is talking about FI? If he is and is saying there is no point in getting a tune without headers, I'd question the advice (but again, without context hard to know) - as with FI there absolutely is a point to to getting a tune, headers or not.

Regardless, one guy saying headers are recommended with FI, does not make it so. Just read the FI section, a bunch of people running FI with no headers and making gobs of power. Not saying headers are a bad idea or won't make you more power, but certainly not something you have to add to your FI budget.

Yeah it was a thread about the hidden cost (additional things you need to think about buying after buying a supercharger), good to know its not a game changer

I got sent to the state smog ref with a CAI that had a CARB EO number and sticker right on the part. The cop was just an idiot. Looked all around for nitrous lines that weren't there. Then said the sticker didn't count, it had to be a plate riveted to the part
