I can't wait for the long tube headers thread, I was going to buy the F.I. hfcs, but I figured why buy the hfcs when the headers would replace that anyway. I hope tony makes the, catted so its not super loud.

must have super loud!!!

^lol, usually companys make 2 versions, one thats catted & one thats not. I am looking foward to see what tony has came up with for the 370Z. The more parts the better ;)

Will the longtubes come with or without cats?

no cats...just straight headers...

how do u know that there will not be a catted version?

highly unlikely that he will make catted headers...kinda like a oxy moron so to speak...

although i beleive that the headers will have 02 bungs...

We have talked about doing a few different versions. Do not rule any option out. You must stay tuned...

Cool, thanks Tony. How's the new F.I. website coming?

Not to speak on their behalf, but it won't be too wise of a business decision to only release catless long-tubes. Take a look at how many on this forum have high-flow cats vs. test-pipes, and that will give you some indication of the market share they will be missing out on.

Every reputable manufacturer of aftermarket long-tube headers for most other cars offer cats as an option. I can't see why Fast Intentions will be any different.

We will stay tuned!

Alot of work, Between my designer, my programmer and me I think it will turn out great but it is taking longer than I would like. Hopefully it will be ready to launch soon!

Well put and just stay tuned, I think you will all be pleased with the options!

On the flipside: Headers are a royal PITA to install on our cars, and the running opinion among us that installed the Stillen short-tubes is that at least without ECU tuning, they aren't worth the expense and install effort.

Obviously the long-tubes will hopefully do better than the shorts (probably both pre- and post- ECU tuning for them), but they're still going to be a relatively high cost/pain:gains ratio compared to most other available bolt-ons. That probably means most of the market won't bother with them, and that for those that do want to go the extra mile for the headers, dealing with the lack of HFCs (using O2 fakes or ECU tuning to delete the code, dealing with legality in some states, etc) is a relatively minor issue to be concerned about, all things considered. Just my $0.02.
