Hey,

This might be a dumb question,
But I looking into for my 01, getting Cattman Headers, Straight pipe, And Cattman Catback Exhaust for my car and was wondering if By doing so should it be tuned? Should I get the JET ECU upgrade? http://www.customenterprise.com/view.../vts/design017

OR SVACII? to get the most amount of power out of it?

What gains am I looking at?
Anyone have a Full Catman System? I seen a bunch of catman and Frankencar mixes but not full.


Any Videos? Searched and cannot find Pure ones. Thanks.

 

most wont get tuned with just exhaust mods, but there are gains available, whether modded or stock, many just dont think its worth the tune until u do some serious modifications, (exhaust, headers atleast) being the minimum of mods.

 

look in the exhaust sound sticky...

You can get an Apexi S-AFC II to tune and pull more power out...

 

I thought some one pulled a 15whp gain from dyno tuning with a S-AFC II and they only really had a full exhaust.

EDIT: it was 17whp

Here is the link: post # 5....

 

VACFII or a SACFII? which is better. i already get intake, advanced timing. hyper ground. small stuff..

 

if you're getting headers, i would def tune... like upstatemax and mecca said.

except, i would get VAFC where there are more tunable points available.

not sure if you like loud exhausts, but with that setup you're looking at, you're going to be hearing it from your cabin and droning on the highway...

 

I honestly dont know much about the VACFII, I had a SAFCII in hand, but my fiance got pissed and made me dump it on ebay when she found out I had to spend a few hundred$$ more to get it installed and tuned...

 

after browsing all motor forum, i've found that ppl tend to essentially state "VAFC does everything SAFC does, but more"...

so far, i haven't read anything about anyone not agreeing with that, i dunno much about either of them.

 

Upstate, that sucks man.

Im looking at the cattman headers, and cattman catback, and catman exhaust.

so i guess everything. My goal is to bash any loud fart can honda/focus etc. on the road. Looking at gettin in January, but trying to see what I need and how much it cost. etc.

and slowly make into show in hawaii.

 

I quickly looked at Apexi's website and it seems to me that it is aimed mostly at honda owners with a vtec engine. but if it does everything a SAFC does and then some... I would spend the extra $50 it seems to cost and run it.

 

Just to let you know... the price difference between the Cattman headers and HotShot headers would pay for the SAFC or the VAFC... just food for thought, ignore it if you are dead set on Cattman.

as far as having to dump the SAFC, I guess I cannot complain; she was quite the whole time I spent $1,500 on a whole new exhaust and $800 on my coilovers... I guess it was the straw that broke the camels back. Soon enough I will get another one.

 

^^^ werd! and very similar performance gains

upstate has taught me some!

 

Yah I dead set on cattman I think i gonna be spend about 1600 for the header and full catback. w/o the SAFC, those would be later.
I guess not 1200, i was doing a rough estimate without checkin prices.


in hawaii same brandname means better for show

 

If that is what you want then go for it.

I just dont know where you get $1,200 for a full cattman exhaust.

headers-850ish
cat-back-600ish
test pipe-150ish

I get about $1,600 and that does not include shipping and install and I dont suggest doing the headers in your garage on the floor; they were a PIA on a lift with every tool you could want.

 

sorry dumb question, what is test pipe? or is that eliminating by the non cat convert.

 

good luck spending $1200 on full cattman headers...I paid $1300 shipped just to give you an idea...for cattman headers+catback from Arizona to California....and that was when Brian Catts gave me group deal pricing on his exhausts over 1yr ago....right now he's not doing any (especially for the Gen2s) and shipping to Hawaii would cost double of what I paid for shipping to Cali...

VAFC is basically an SAFC with an RPM switch....it also has 24 point tuning versus 12 point for the SAFC

 

yeah it is a cat delete... just a resonated piece of pipe that goes in place of the cat conv.

 

a test pipe is just a small pipe that replaces the catalytic converter....usually it can be made at a muffler shop for cheap...just tell them what diameter size piping you want

 

so its like those ones u get off of ebay from like 50, lol or no good those ones. does that actually make a difference going from that to a highflow cat?

Thanks,

I did not know that, with the 24 point vs the 12 point, does that mean its harder or easier to tune because of the more points?

 

I dont think it makes much of a power difference between a highflow and a test pipe... It does however have a sound effect. A highflow cat keeps it a bit quiter and it makes the exhaust "pop" less, I personally cannot stand popping.

 

I would think it takes more time, but it is more precise to pull a bit more power out...

 

Good to know, I hate the pop sound, thats too much rice for me. a lot of honda's over here pop and i hate it.

 

honestly, a test pipe or maybe even a high flow cat will only increase sound and barely performance, if anything. since you're going for a full headers to catback exhaust set up from cattman, i might suggest to keep away from any type of hi flow cat. i would stay with stock, esp if you're afraid of any popping sound.

 

I dunno about the VQ30's...but the VQ35's with a straight pipe gives off a NASTY (in a good way) @$$ pop....doesn't sound nowhere near a civic with a fart can...it sounds more like a race car exiting a corner giving off a backfire

 

i have a test pipe from warpspeed and it sounds really mellow wiht my y pipe and stock catback... similar to G35...

although it will def give a popping sound, not sure if it's going to be good or not... depending on tastes. my setup will include a test pipe, headers, and cattman catback, so i don't mind the popping.

 

anything paired up to the stock muffler will sound very mellow....whether its fully headers and test pipe...or just a ypipe alone...the stock muffler does a great job of sound suppressing while keeping the flow of exhaust...I will give nissan props for engineering such a great muffler

 

If you're not looking to spend that much money, you can always get a y-pipe instead of headers since the 00-01s don't gain that much more with headers over a y-pipe.

 

And btw, tuning with an AFC (S-AFC II, V-AFC II, eManage Ultimate, etc) is probably a good thing regardless of what mods you have, but how much you gain all depends on the AFR of your car with the mods. Gains are not the same across the board and just because someone else nets XX whp with tuning doesn't mean you will get the same.

 

safc: 12 points to tune timing and a/f ratio throughout your rpm range.
vafc: 24 points to tune timing and a/f ratio. you can change your settings for two modes, one before vias and one for after vias opens. i think its at 5200 rmp stock, and you may be able to change it to somehwat lower rpms with vafc as well. kinda like honda's vtec opening at different rpms.

 

Oh, I didnt know that

What would be the gains with cattman Y-pipe and full cattman catback exhaust

VS.

Cattman Headers and Full Cattman Cactback Exhaust.

On my 01?

 

on an 01, headers are definately worth it. with the y pipe youre only eliminating 1 precat, with headers both precats. If you are ready to invest a lot of money in your car, I'd go with the headers and not just stop half way with a y pipe. especially if you eventually want to turn it into a show car.

 

Just to point out, the elimination of the front pre-cat is not where the gains are seen, gains are mostly from going from the stock short manifolds to the manifolds with the longer tubes and equal length collectors. That is why a Fed spec conversion doesn't gain much hp even though it removes the front pre-cat, because it still retains the stock manifolds.

It is true that if you want all the hp possible, then headers is the way, but like I said, if money is an issue, a y-pipe isn't a bad option. Of course if the plan is to get headers eventually whatever the reason, then just get em.

$350 for a Cattman y-pipe for 12+ whp

vs

$850 for Cattman headers for 20+ whp

(these are untuned estimates and will vary from car to car)

I don't know anything about show cars though, I just thought they needed to look real good and have cool lights/gadgets, didn't think they'd need to be fast just sitting there in some warehouse.

 

I would love a set of Titanium anti-reversion headers along with carbon fibre intake... *drool*

 

I will be able to answer this question in about a month. Right now I have the cattman y on the car along with the full cattman catback. I will have the gen 2 cattman headers installed within the next two weeks hopefully and I do plan to dyno. I'll post up the results when I get them.

 

I aint planning to get till Jan, PM ur results when you get it done, What year is ur max?

 

His username and profile suggest a 2000....

 

what are the typical gains of an 00 or 01 max with full bolt-ons and a SAFC tuned on the dyno? I know the 3.5L's with full bolt ons gain a ton with the SAFC...but I don't think anyone with the 3.0L 5th gens have posted their results...

I to will have the full cattman setup...gen 2 headers and catback...I would wonder as well if a SAFC or my e-manage would net me any gains that are worth my time and money for the dyno tuning...I guess in the end, there is only one way to find out...maybe after I get the headers and catback on, I will head on over to the dyno and see what they can squeeze outta my 3.0L with my e-manage...

 

As puppetmaster suggested, my max is a 2000 model. The first dyno that I do will be without tuning, just as the previous one. After I pay off a little debt, then I will be able to tune the car to it's full potential, but the dyno's that I will be posting in the near future will be of an untuned '00 with a cattman ypipe and then the same car untuned with the gen 2 headers. The car runs dangerously lean now througout the entire rpm band, so I think that a good tuning will definatly result in better gains, I'll keep everyone posted as I find out myself.

 

Ask sloppymax for some input on that.

One thing you could do is hold off on the AFC until you've installed the headers etc and dynoed without tuning. If the AFR looks like it can be improved, then go ahead and get an AFC of some sort.
