When you read about them, they claim 10+ hp, but i don't see that anywhere based on posts

Long tube headers are your bets bet for decent gains after having all the other bolt-ons. It's pricey though with install so it comes down to how much you are willing to pay for it. Only other things would be pulleys (but it won't be a hp diff you can feel) and cams which are just as bad or even a worse HP ROI than headers. But it comes down to what those extra whp are worth to you and that varies from person to person.

i can agree with that, all comes down to how much you're will to spend. might be better to save the $1000+ there and invest it in something else or start an account for FI :D

go spurs

^^ best post on this forum lol

and I'm a Lakers fan, but gotta respect Pop, Tim, and the spurs organization

Thanks for all the input:tiphat:

I still don't know what I'm going to do :rolleyes:

I want the power but doesn't seem like there's enough bang for the buck

sit tight. see what the new z has to offer if you can stand to wait

Headers are definitely on the low end when it comes to price vs gain. However, if you are planning on staying NA, and want to get the most out of your motor NA, then they are a must. I've got the same exhaust set-up as you (F.I. TDX CBE w/ 18" res) and I went with the F.I. LTH's mainly for the mid-rang advantage of them over the peak whp. They are definitely a quality product and Tony, as many have said, is great to deal with. Here is a short clip of mine in the dyno in case you are wondering about sound...

Hope this helps in you decision-making :)

Yeah, I'm doing the LTHs because I am pretty set on keeping this car for a long time and use my money for things like a house rather than a new Z. If you can wait a year, I would. The next Z has to be coming out by 2016 which means an unveil sometime late this year or next year.

Not a compelling reason to install, but headers can give you that cool back-off gargle-burble kind of noise.

So can burritos, I suppose.

NA mods are kind of funny, you do a couple and you get great gains, then you do more and hardly get anything, and then if you go nuts and do everything all of a sudden you end up with a ridiculous number because you have uncorked the entire system (I'm not talking intake headers exhaust here, I'm talking strip it to the heads and start over with all race parts).

anyone know whats the highest N/A whp made?

fixed ...


it can be relatively easy to fake some pull to make it look like a very high whp.
So just saying that guy had 340whp doesn't mean much because for another reason that no dyno read the same...

I wouldn't do it. Minimal gains.
