ok so the search has been down for a year and i tried my best to comb through the threads. does anyone on the board have side by side experience with the hs and cattman headers? (ahem steve at swa lol). there's a 3 hundred dollar price difference and i want to know how it's justified. i live really close to hs so i'd probably just get the set from them locally and either have them or TET install it since they said they haven't had problems with previous HS installs on the 5.5gen despite what some members are saying. Is the cattman of higher quality?? more power gains?? is it any less prone to corrosion than the hs?? heck, does it sound better?? otherwise i see no reason to buy the cattman set

how much does each go for?

Qmax03

i know cattman goes for $825 always heard good about the cattman headers and i know they can put down 30 hp easy on a 2k2 k3.

mistermax

30?! surely that is crank hp and not whp right?

hey ighettoboyi: there was a thread i read earlier, that if someone from here goes to hotshot and purchases a set of headers, they will install them for free to prove that they are a good fit. Just what i heard so i would call them and see if they are still offering to do this.

mdloops

I think the gains are both around 15 WHP (I have seen dynos for both). The difference is the fitment. The hotshot takes a little more time and effort and the cattman are pretty much idiot proof If you are willing to put the time in the I would go with the hotshot, but if you are paying a shop to do it I would buy Cattman (labor/hr costs).

Nope its 30hp to the wheels. I did a dyno of cattman y-pipe to cattman headers. It was done with dynojet and tried to dyno on days where the conditions were very similar.

It looks like cattman's are slightly better designed too. Also note that that car that gained 30whp at one point is already highly modified (compared to what is available NA).

mistermax

does anybody know what stock 2k2 autos put down on the dyno? to my understanding the dyno shown here with the cattman is stock or at least fairly stock before the headers. what is the whp difference between stock auto 2k2 and 6spd?

stock 2k2 manual - 204
"" auto - 197

HS and Cattman headers put down the same #s too, the difference between them is so small its negligible.

mistermax

anybody have a cattman vs hotshot header comparison dyno? by the way fezzik, great dyno charts! the results are amazing! VQ35 PRIDE!!

bgates1654

I cant imagine anyone wanting a dyno comparison enough to buy both sets of headers (~$1350 for both) then paying for 2 dyno sessions ($120-200) as well as installing (paying or self install) them both and giving them enough time to break in. Nor can I imagine people want to see this comparison done enough to donate to someone who was willing to do it but didnt quite have the money. Although I am sure we would all love to see it happen.

Oops on the highly modified comment. I just looked at it again and they only have an intake besides the ypipe/headers.

they made that offer to me. i don't know if it's still on the table though cuz it was a couple months ago that they said that. however, i doubt they even came up with a new batch.

shouldn't it be the other way around? if i want to do it myself i should get cattman (spend a lil more on the unit and save on install) or get the HS which supposedly don't fit taht easily and spend 150 or so on install at TET (or for free from HS i guess). Andy at TET says they haven't had problems with HS headers though so I dunno what you guys are trippin on.

and whoever said you need mods for the ecu is WRONG, i'm pretty sure it gives you nice gains stock

joebangaa

iTrader: (3)

o and the HS offer for install, they want the car for a couple days to fabricate a NEW batch so it's not just simply installing their existing one and proving to the .org taht it fits, unless of course the original fits that easily that they find no use in making a new batch...

offtopic

i wish the search function worked, the first three pages of threads are today, could be toned down to the first HALF. not complainin

mistermax

where is the header having fitment issues? is there any drilling, cutting, dremeling necessary for a proper fit? anybody have pictures of the improper fit?? oh yea and another thing, is it necessary for me to reset the ecu after the headers install to see/feel the gains?

E55AMG2

iTrader: (4)

Mister: I had no fitment issues, they slipped in perfectly. I guess it depends on what Cat and B pipe setup you have. As for the reset, yes. Otherwise the car will not run properly (too rich)

mistermax

cat and b pipe will be stock. what are u running e55? and when did u install? just recently or did u get one of those early batch ones?

E55AMG2

iTrader: (4)

I got them 2 months ago. Warpspeed Metal Sub Cat, Warpspeed B

mistermax

any word on how they fit up to stock cat back?

E55AMG2

iTrader: (4)

The cat is the same length as stock, but bigger ID so they should bolt up about the same.

^^ whats the minimum donation amount haha

claudiusmaximas

isnt it 20$

max5spd

iTrader: (11)

Dunno what the minimum is. I donated $20 and I got access.

joebangaa

iTrader: (3)

so are the differences negligible or what?? e55 do you have a set, if so how do you like it? can we engrave this in stone like the bible?

joebangaa

iTrader: (3)

ok from what i can tell, both hotshot AND cattman aren't stainless steel (someone please correct me if i'm wrong). cattman is made from a carbon steel coated with something to prevent corrosion correct? (like the hotshot set)..

if that's the case which is less prone to corrosion because I want these to last a long time. only in this case could i justify the extra price for the cattman

E55AMG2

iTrader: (4)

The HS ones are ceramic coated too

joebangaa

iTrader: (3)

ok not to be mean or anything but no **** sherlock, that wasn't the question

i had THOUGHT taht the price difference was cuz the cattman was stainless but i realize it's not, so the question again is which set is less prone to corrosion and wear etc

E55AMG2

iTrader: (4)

<---totally missed that

I believe they are both about the same when it comes to corrosion resistance and whatnot. The difference in price may be the fact that the cattmans fit both the 3.0 and 3.5. Again, I am not sure of this.

joebangaa

iTrader: (3)

hm not a bad idea, you have the HS on urs right?

quick recap: ypipes pass emissions after you warm up the cat, is this the same with headers? even in cali? yes right for soem reason i thought i read yes somewhere a long time ago..

E55AMG2

iTrader: (4)

Yes, HS on mine.

I believe if you have the stock cat (and its still working) you should be able to pass emissions. However, if you have a race cat, this will not be the case.

joebangaa

iTrader: (3)

so if my cat ever gets shot instead of buying a hi-flo just get another oem?

e55 do you have any dyno sheets with your HS?

Cutler

iTrader: (3)

Take your stock manifolds off and just run open headers....

GBAUER

iTrader: (2)

Dumb question: I want to add headers this summer. Can I justify it to my (then to be) wife by saying that it'll increase my gas milage? Long shot, but I think I can pull it even if it only increases milage by half a mile per gallon.

Cutler

iTrader: (3)

Yes it helps on gas mileage if you don't floor it all the time

NmexMAX

iTrader: (22)

Which is hard not to do when they're installed.

Or you can just say it's normal maintenance.

GBAUER

iTrader: (2)

She's blonde: maybe that will work!

Of course I NEVER floor my car. That might lead to wheel spin which would be illegal. And, no way would I ever race either!

NmexMAX

iTrader: (22)

So you're saying you just want better gas mileage out of these headers?

Hmm, smart, the will pay themselves off sometime in the future with all the fuel you'll be saving.
