And as I replied B4 when you can compare Cattman's product with other aftermarket exhaust builders his work is up there with Billy Boat (B&B), TTI, Borla, etc. Have you ever priced any of these folks exhaust systems? I'm curious what aftermarket exhaust builder you've found online for $400 and equivalent quality.....I don't think Cattman is GOD, but let's face it...He's product was artful enough to catch your eye, my eye and everyone elses.....even the performance, and exhaust note side was luring for me......So for half the money why didn't you take your ride to one of these SKUNKWORK exhaust shops and have them copy Cattman's Catback for half the money? You know for the looks........you ever priced and seen Brullen product GH17? Brullen exhaust wants $745 for a 3rd gen catback w/quality nowhere near Cattman's....Just trying to open some eyes cause the $$ we're spending on his catback is toward the bottom of the food chain... If you wanna a real custom SS setup with flanges here in Houston is starting at around $1100 on a small car....I've got a T409 SS custom catback system which cost me $550 with the cat on my DD 86.5 Hardbody pickup...It's a 1 piece system....

 

No one’s proven any ‘gains’ because no auto has dyno’d yet. And if 4AT’s have hit the track, they don’t have a valid comparison run to compare, most notably, DA for the night they are comparing to.

 

i hate when we get info the fine specifics on somethings... how about this, i went to the track with the 3" and never ran a better time (i did) i was actually .2 sec slower.... its a petpeeve how weather, DA and all the BS becomes a factor when there is no proven gains just to save yourself from looking dumb you try to throw in the slight intangibles (you- in general, not nmexmax) if so be the case there is hardly anything that can be a proven difference... when people show improvements its a big celebration and weather and DA and all the bullshyt isnt a factor but if there is no gains then here comes a million reasons why.... with all my mods and a 2.5" exhaust i ran a 13.704 and with just the 3" change and a cooler temp i ran a 13.999, how is that for comparison??? i dont post that as i've made a bunch of passes with my 2.5" setup vs 2 on the 3" and one run was messed up where i never received a timeslip... so yea... what now???, is that $850 well spent... i dont wanna hear ish about quality, as the perpose of buying a Performance exhaust is mostly because of its performance... whether thats the reason you bought it for or not, if you cant get performance from a performance exhaust then its a poor buy, you personally just prefer to still buy it

 

I thought I proved the performance point when I proved that I saw more airflow? (quantitative)

And saw less traction? (qualitative)

If anybody in here wants a quiet exhaust, it's me. I’ve been through a whole heulluva a lot of exhaust set-ups. I tried this since I liked the dyno given with Merlyn (6MT, yes). The gains from the Cattman, IMO, are too much not to enjoy, even if it is a little loud. I don't go by 1/4 mile or any other track times, so that's a moot point for me.

The car has a different attitude, does not ever keep traction in the middle of first, or on the shift from 1 to 2. This never happened before the ‘change’.

The air flow that I made a very specific effort on the Cattman thread to boast but never caught on, and if it was, it was never appreciated.

The obvious points.

1.) The MAF is seeing more air. This is obvious.
2.) The AFR got leaner, needed to add fuel. This proves #1.
3.) I do not get air flow drop off past 6000 RPM now, whereas before, I would.


If I ever make time to dyno, it will be interesting. I don’t hit the track, so that would be an invalid comparison since I have no baselines to compare against.

 

here is my thing... i know most will disagree but we are all different...

if my car dyno'd 1000000000000whp and 200000000000000tq but only runs a 13.9 then its a bust... if on paper i can see a difference but it cant show it on the street/track/wherever else then its a gain i'd rather not hear about.... i applaud you and even send you pms about setups but lets say for example i do the LR intake and i gain 12whp but somehow my powerband is shifted where i dont get any better times on the track, what good is it to me???

 

That's why NMex is so big on "area under the curve" as opposed to peak numbers.

 

and im big on seeing a difference on the drag strip... all cool we just got different things that makes us keep doing what we do

 

If that were me, I'd go in November or whenever is the latest in the season and at the latest possible time @ night.

Or, wait for a storm, and then try and go when the best possible DA's are. This is getting into the prime time of the year for that.


Members don't usually break old 1/8 or 1/4 records in May/June/July/August.

 

how about this again......... nooooooo mod changes, remember my car was out of commision for a bit... last november was my PB at 13.84@100, i previously beat that record i believe it was last month or two... its in the 1/4 section... look at the post date, im not trying to be an arsehole or play devils advocate or anything, im just telling you how it is

 

That's true, but Devils Advocate would be asking for and comparing DA's, since that's really all my point was, and there's a far better chance at better DA's in cooler months. And I did say usually.

Tire pressure ... traction ... those are Advocates too ... but all my point was that I bet if you ran in late November identically to what you ran whenever you broke your record, odds are, the November (or rather best DA) would end up as the best time.

There have been times I’ve thought of hitting the track, and I went ahead and saw that my local track holds events until Thanksgiving ... and they have the typical ricer deal that lasts IIRC, to like 1100 at night. I’d be there at 1000 on the day before they closed.

Of course I’d regret it and think that I could launch better, etc, and be pissed until April when it opens again. So maybe I should start going now so that I can actually have a chance at a decent time come late November.

 

i say you go... corrected you should have waaaay better times than me...

 

a fellow orger went from 265 with a 2.5 to 278 with the 3.....enough said

 

its not a bust...u didnt run the same way did last time when u ran that 13.7...u had a intake set up and more weight

 

jaypee........................... i'd like to see more of these auto's actually dyno... so many of them have the exhaust, i remember it started from the law who promised a dyno and he just went MIA, everybody else after just bought it just because.... our community loves to add to there mod list, thats it... its a community to show who have the better mod list... all show no go i say............

 

im not saying it doesnt make a difference, i was moreso trying to make a point to most of the ppl on here that i quite frankly dont give two ish what something says on paper, if it cant do it on the track then its a bust.... most ppl come here with a puffed chest to say i have "this and that", and with "this", i should do "this" and because of "this" then my car is now "that".... i just hate those factors... i "believe" i got gains from my 3" but i just never ran a PB on that pass as previous it was 13.7@ 100 now i did 13.9@100 what would it look like when i run a 13.7 again... what im saying is, without me saying any of this, there is absolutely no proof that there is any gains on the 3" on an auto, so for all the "quality" talk, that means ish to me

 

what intake?? what weight???

 

did you not have a ram air set up???....did you have all the crap in your trunk when you ran that 13.7? when u ran that 13.9 did you take the time to do everything u did when u ran the 13.7?

 

those crap have been in my trunk since my car was down, i've never taken em out, last time my trunk was clean, was last year november... no i didnt have a intake setup, i ran with jaypee's intake once and ran a 13.8 then i went back to my setup as he also had to run....

 

jaypee's intake is a ram air fool....lol....and on top of that neither one of your passes was clean passes ..............................

 

yes, but i never got any better times.......

 

was it on the same day? same temps? otherwise that statistic is pointless bud.
hell an exact same setup can yield diffrent numbers one month to the next on the same dyno.
and still....13rwhp MORE? just from switching to a .5 bigger exhaust? heck LS1's dont even see those kind of gains from switching to a "bigger" exhaust. i think your fellow orger may be confusing you.....or i just out right call BS.

 

Oh god, round two. We already went over the outside conditions once in this thread.

 

look at the gains.... if you believe weather was the major factor in those gains then every last auto, 5spd or 6spd in here cannot prove that they made any power with any mod... cattman and nwp lied about their products as the tests wasnt dont at the same time as im sure the weather changed by at least 1*..................... these are the small intangibles im talking about

 

Can we put it like this, 1-2whp on a dyno with different conditions means there is no real gain(for those of u that dont know Corrected numbers factor in the weather and other conditions that will alter the numbers), anything over 5whp(especially with the HP levels we are talking about) means something changed.

If a car makes 260whp with a 3" exhaust then goes back the next day with a cutout and makes 262whp, im not going to say the cutout helped, imma say it was a massive waste of money.

there my semi serious poast.

 

which is 100% accurate IMO

 

i saw that argument but i thought it was referring to 1/4 times...my bad

the green line is the 5.5gen

 

ok that makes a little more sense. meaning if he was tuned to begin with (instead of being untuned) when he dynoed with the 2.5 , i dont think he would've put down 13 more "just" by switching to bigger piping.
so i dont think we'll ever know what the TRUE gain was by switching over to .5 bigger piping.

 

that would be a fair comparison... if he was un tuned then got tuned with a 3" for all we wouldve known is that the tune gave all the gains... seeing as though he was already tuned, there was no extra hp squeesed out of the tune, just a change in piping....... perfect example if you ask me

 

have to agree, you dont even see those gains from oem to aftermarket, that is very high % gain IMO the best catbacks may see a 15 whp increase over oem, atleast in years of reading chevy,ford,import mags

 

tuned it was 265whp like i said earlier and all he did was switch to a 3" and it went to 278whp

 

the dynos are up ...see for yaself

 

U should start messing with the RWD manifolds and see how much power u can squeeze out of those. Thats next step for me now that i have the 3.5 manifold worked out on this 3.0.

 

are you agreeing just because you dont want to believe or do you have a good reason for visual evidence??? if you cant believe this, you are just out right stubborn because your mind is telling you its "impossible" for a maxima to do this

edit: so you are going to believe what you read but not what you see... so if a book says maxima's cant run 12's but you see it happen with your own two eyes you wont believe it???

 

Datdude you haven't dyno'd running your 3" yet either....I'm trying to get a day off soon since we're working a whole lot due too the continuous rain over here......I first wanna install my NWP, coilpacks and 6th gen VC, and new Iridiums +.....B4 I go to the Dyno....just can't seenm to get home 8pm, today has been the earliest in about 3 weeks.....I'll be doing my dyno hopefully B4 the end of Oct. 2010.....

 

im sure if his car was up and running the dyno wouldve taken place already...

 

I'm more mature and yes I like it on the quiet side myself!
Yes your statement regarding an increase in airflow was appreciated!
Yes my ride's attitude changed also.....almost had to put her in time out...LOL!
I'll be dynoing this 3" A/T soon!
This is to GH17....You ran a 13.704/1320Ft did you ever back up that run 1 or 2 times after that?

 

13.70 was with the 2.5" catback, i ran twice with the 3" one run was 13.9 and i didnt get the second timeslip as they messed up my times and gave me a slip with another car number....

 

Maybe we like too go but not show (you)LOL!!!.....Everyone doesn't live to beat the sh!+ out of their car and have to deal with problems like what you had to deal with when your was sidelined.....I enjoy driving my car and stepping into the throttle and enjoying it's thrust, without flooring it WOT every Friday, Saturday, and Sunday....I like going to the drag don't get it wrong....just now and then.....!

 

and for years everybody has been modding the same kind off cars and getting the same results over and over and over. the VQ35 has a lot of hidden potentail. When they put this motor into the max its held back a lot by restrictive bends,pre cats and this gay a$$ ecu. So once u start to tamper with those 3 things you get stupid amounts of HP increases. Perfect example.......15-30whp jus by changing the headers (lets not turn this into a header thread ) 350z's dont pick up power like that and we have the same motor. So that just goes 2 show that when the 3.5 was put in the max it was limited to the amount of power it can really produce. So thats a big part as to y we see the hp gains we do off of doing simple ****.lol
