I'm sure this subject has come up before, but I checked up to page 20 and didn't find my answer. Sorry if this is being repeated.

My mechanic tells me that the headers he put on a 5th gen had fitment problems and took him 12 hrs! He told me they don't add that much power either. I think he just doesn't want to be bothered w/ em and shot me a price of $350.

So what's the truth? Every post on headers I've seen claims around 20hp-25hp. Anyone else have fitment problems(hotshot)? Were performance gains noticeable? Is he trying to rape me or is his price on target?
Thanks Guys

 

Cattman headers have fit perfectly on most of the 5.5 Gens that I know of.... and they will give ya the 20-25 whp that you've heard... $350 sounds average to high... someone else posted not too long ago that a place in MA was gonna do it for $240.

Dynoes from Fezzik are here:

Thanks puppet. That was a perfect thread. That's the first time I've seen an increase of 30whp form headers.

 

No problemo... btw, I think ya need to brush up on your "searching".. this was on page 4; lots of headers install info there:

Go with the hotshots. I have them and The finish and quality looked great and fittment was good too. + i saved 300 dollars compared to buying the cattmans which aren't even being made as of right now.

 

Don't worry Chris, I wasn't bashing em... I just don't know enough about HS to comment... I know you and Mike (Blackbird) and others swear by em...

 

Man just do the install your self, i heard mike saying it took him like two hours to install headers, i think. Think he mentioned something about being able to swing the engine on the mounts, so that its easier to install the rear cause when looking at the engine the front doesnt look to hard to mount. Atleast on the 3.0 the 3.5 might be crammed, not sure havent spent alot of time under a 3.5. PM Mike(blackbird) about the engine swing thing. I dont think they make hotshots any more but catman is supposedly makeing more of theirs. Man i want headers too, i want the hotshots, i gonna steal Mikes muahahahhahahah j/k Mike.

 

HA you say that now. Wait till you get under there and put those b!tches on yourself and then you'll be cursing and saying "why didn't i just pay a shop to do it". Mike did it so quick becuase he had a lift, air tools, and was a nissan mechanic.

 

Oh i know, just letting the guy know there are other options available.

 

i'm going with the hotshots and apparently they make a world of a difference according to any member that has them... I was quoted 200 by a shop owner I trust so 350 seems to be too high... i'd say the median point is $250 for headers installation.

 

Yup. Crazy to do it without air tools. A lift makes a big difference.

Took a day to do mine with help without the lift. Rear bank is a biotch.

 

is there any power difference between the cattman and the the hotshot headers?

 

just wondering if nissan has the right to void our warantee w/ headers installed. I remember a nissan tech told me that an intake would void the powertrain warantee.

 

Basically they hae to prove that the mods done to your car caused a fault but with nissan unless you rich and can afford a legal battle, yep they'll say they void your warranty, hell with nissan service YOU driveing the car voids the warranty.

 

can u find a cattman headers for 02 max cheaper dan 800 buckzz

 

Well, headers are technically illegal since its considering tampering with emissions equipment (pre-cats) so I think they'll definitely have something to say with regards to that and not so much the powertrain warranty (although, I need to go look over those terms again).

 

headers shmeders u guys are just funny...Turbo is the way...

 

Not if we want to stay n/a

 

you keep your headers if you go s/c smart guy

 

ehhh he said turbo, in which case you wont be able to keep the headers smarty pants ...

 

oh how did i miss that post? i just scrolled down fast i guess, but how the heck did i miss all those colorful a33's

 

Rainbow hmmmm

 

Whatever, I still think a majority of the people here (myself included) do not have the know-how or resources to deal with turbo and the issues it brings.... N/A is more than enough... just keepin it real here...

 

Not only that but N/A feels more like an accomplishment ... I've always been a fan since I couldn't ever afford F/I, and well, to think the money I spent N/A could have gone to pressure, but now I'm just an n/a junkie ... my fix comes with normal atmospheric pressures, (590 torr) Yes, I'm high elevation ..

 

I absolutely agree with ya there... I've been trying to do my homework in the AM forums.... just lurking about...

 

do some reading here before you laugh it up.

Turbo is the way huh?

 

You guys are all wrong.....SPRAY IS THE WAY!!!!

 

Are the HS headers CARB approved? Anybody know?

 

Thats just cheating

IMO on 3.0 the only way to unlock the true pontential of the car is through FI

 

for those of you with a full cattman setup didnt anyone dyno the car to see what you got from it

 

If the guys that have both cattman and hotshot headers are happy w/ their product, the question is which system delivers the most gains? Any of you guys w/ hotshots get on the dyno yet?

 

This question will never be answered.

 

What I don't understand is why you wouldn't want to jump on the dyno to know you got what you paid for. I'd want to make sure I got at least 20whp gain.

 

Well, people have dynoed their cars with headers, ya just won't get a one to one comparison of headers on the same car because its just not feasible to buy 2 sets of headers, install one, dyno, pull em off, install the other, dyno, etc etc. You get the picture. I have dynos of a 2002 6 speed with Hotshot headers if ya wanna see em. PM me your email address and I'll send ya the files that I got from Larrio.

 

And....?

 

Ya i want to see the gains...the headers and the Techno ECU are going to be my first upgrades on my 5.5th 6 speed. I would love to see numbers.

 

Cattman told me his headers give about 25whp on a 02-03, and work much better on a VQ35 than VQ30. I haven't dynoed anything yet, but the sound is awesome.

I doubt there is a significant difference in gains between Hotshots and Cattman's. I was buying lots of stuff from him and got a 10% discount if I bought the headers too, so for me it was worth it.

 

lets say i have an hi flow intake and exhaust.. im about to put headers and ill probably take out the resonator. does my cat cause a lot of restriction?? is a high-flow cat worth it??

 

Then search for Fezzik's dynos... they're on here somewhere... it'll be well worth it...

 

No... its not... minimal gains, according to most... but then again, I've never tried it or seen dynos (probably cuz it hasn't been worth it).
