Excellent!!!

The High Flow Cat that I purchased from Advance Auto Parts
cost me like $80.00. It's a very good Universal High Flow Cat.
Matter of fact it's the same size as the MagnaFlow and several
other brands out there. I'm not sure if it's the pic but it's not very
big @ all in my opinion. There is a size down from it that maybe looks
smaller because of it's circumference. Here a shot of the design that
I currently have on the maxima. Thanks again for the comments pertain-
ing to this project. I'm sure Cattman's phone is going to ringing out the hook.
Took the maxima out for a good "Get on it" drive yesterday evening. Mannn...
you can really feel the increase in power, performance, and Ohhhhh Myyyy the sound.

 

It's always good to hear another satisfied Maxima owner after a header install.

Best mod for me up to this date.

 

Very nice, I just had my car in for a cat replacement, due to the P0420 code

 

You shoulda just gone with the headers!

 

so question..., I could order cattman headers, order a different cat, then 2 mufflers of my choice and thats it? have to order aftermarket resonators too? Sorry, just really interested in chnging out my exhaust system headers back, but need some info on what all I will need to order for the shop to have for the install...I read something about O2 wireing and all that having to be extended or something...Is that common for muffler shop to already do, or are these things I also need to have ordered?

Diesel

 

Order Cattman headers, y-pipe with hi-flow cat, and either a full catback exhaust, or just mufflers (just mufflers would be cheaper, but I say if you are doing all of this, go for broke!)... catback exhausts typically come with resonators already... it just depends on what kind of sound you are looking for.

My setup: Cattman headers/catless y-pipe and a Greddy SP2 exhaust.

I posted a rev video here:

http://forums.maxima.org/6964412-post37.html

There is a drone in mid-RPM but I like it...

 

I was looking at either magnaflow or remus. I like the stock 4 pipe look and looking a little deeper sound than the greddy put out. Setup looks nice. Ok so a full catback exhaust will usually come with the resonator mufflers and piping? magnaflow or remus doesnt have this I assume though so what would be the right thing to do?

 

I'd suggest one-stop shopping, since you'd be getting the headers and y-pipe from Cattman... get his catback exhaust too, and be done with it...

The Magnaflow/Remus setup would just come with the mufflers... you'd have to get them welded on in place of the stock mufflers... attacked to the stock piping/resonator. If $$$ is an issue, I'd go that route.

 

nice pics, headers area must on any 02+ maxima!

 

Bingo! Good answer, go with this one. The Cattman catback comes with Magnaflow mufflers anyway right? (dual tip)

 

Yes, 14862's

 

Well i was just comparing the look of yours and apollos converter. His looks to be much smaller, but i guess its b/c yours have more heat shielding around it. This looks like the one i just put on my F250 pick up.

 

[quote=BLACKNESS MONSTA;6965319]Yes, 14862's[/quote


well damn, if the cattman can come with magnaflow mufflers i'm game for that. It's not money as an issue, it's sound. I like the way the magnaflow sound, so if cattman can do the full exhaust with magnaflow mufflers ending the setup, I'll give him a call on pricing for sure

Do you have a pic of the o2 sensors welded to the hi-flow cat? Brian at Cattman was offering a hi-flow cat with two installed ports for the o2 sensors for about $160.

 

The sensors will not be "welded to the cat", they will be inserted somewhere after the cat. I'm not sure how far they have to be behind it, I would expect the cat to get pretty hot, but if we go by their placement on the OEM manifolds I am just going to go a few inches past the cat and have them welded in there.

 

hey so if your gonna weld them in basically where they were stock, do you need any extra wiring or nething?

 

The car has three cats, the headers will replace two of them so it wont do any good to put the O2 sensors back in the OEM spot, we need to put them behind the 3rd cat which is being welded into the Y-pipe.

 

i see i see

 

About this far back...

 

Sweet pics!! That will help. Thanks Chern.

Good morning, I have a quick question for you guys RE:
the CATTMAN Headers. I still have to weld my o2 sensor
bung behind my new Catalytic Converter. I've extended
the the o2 sensor with the Green cap. This makes sense
to me b/c it was the only remaining o2 sensor. Why am
I seeing two o2 sensor bungs/sensors on Deus, Chernmax,
and several other maxima's. So, lets exclude the Green
color cap o2 sensor. What is the other o2 sensor that some
of you guys are running behind the new welded on Catalytic
converter? B/c the remaining three are two Air fuel ratio sensors
and the blue color cap o2 sensor.

 

Both the rear o2 sensors need to be extended past the cat... and a plug put in the open bung.

 

One of the secondary clip in plugs are green and the other is blue.. Both should be extended and plugged into the y-pipe after the high flow cat..

 

You see in the front part of the Y-Pipe 2-O2 sensor plugs hanging down (Green & Blue), these 2 need to be extended back behind the CAT.

 

yea works I have no problems with CEL light only purchased a resonator she sounds great no annoying cheap tone..

 

so are you running O2 sims with a cat-less y-pipe? how long you gone without a CEL

 

Well my car is an 06 no cel light...

 

That's good news that your 06 isn't throwing any codes or a CEL Light.
I think a few 04 & 05 owners here and on the other Org mentioned they
were code free as well. Does anyone actually have pics of the o2 Simulators
hooked up on there 2004-2008 maxima? It would great to view the finishing results.

 

That's good news!

 

Hey guys, thanks for the helpful information as well as the pics
pertaining the o2 sensor wires that need to be extended. Most
likely I'll have that done today or Saturday morning. Quick question..
can that wiring be purchase @ any hardware or Auto store? And does
anyone have pics of the o2 sims installed onto there Max or Altima.

 

nice job bro...outcome looks SICK

 

I got electrical wire that can be purchased at any hardware store. Make sure the soldered connections are solid. You have to tug on it it some and feel that it wont come apart. Use a high powered soldering iron too (the gun type, not the pencil type)

 

I really appreciate the comments guys. Dues will
this soldering gun be sufficient for the task @ hand.
Also, will I notice a difference once the ECM is reading
those two o2 sensors behind the cat?

how much total did this project cost?

 

Chris, I tackled this project along with my buddy who has
his own Auto Body & Mechanic shop. He recently just got
a new lift so he was like bring it in so we can break in the
new lift. He taugh me so much about cars over the past 7
years. Even helping me build my own little shop @ the house
to be the ultimate D.I.Y weekend warrior. To tell you the truth
the only time he works on my vehicles is if the task is out of my
league. Which in this case required a lift to make things go alot
smoother. So, in conclusion on the price... I paid $180 + beverages
and meals for the day. Which consist on breakfast for three, lunch,
plenty of beverages to stay hydrated. He basically made me do a lot
of the wrench work on this project. But he's the master mind behind
tellng me what is what and taking over when necessary. Which was alot!
The project probably would run a customer $300-500 just to do the header
install. Then there extra for the welding, wire extending, etc..... It varies.

 

Go with the higher wattage one. That O2 sensor wire doesnt take to solder like copper wire

 

Here the way i hooked up my sim, but i have to relocate the ground wire (the upper black wire, spliced with grey cable on the sensor harness) to the chassis ground instead of the sensor ground; that way the sim blink slowly and working fine (pulse between 0.3 & 0.6v on both secondary sensors)



BUT you don't need to extend wire to instal sensor behind the cat on the y-pipe AND use sim, only one of method is recommended; if you want to use sim, don't waste money on extend the sensor...

here how i set my 2 secondary sensor with my sim (on my rad fan braket) :

 

Thanks for the great pics of the o2 Sims installed. This is good news!! B/c I want to remove the small pre-cat that I installed already. So that I can just have one resonator for better sound and less restriction. The way it's set up now is Headers, Y-Pipe, small pre-cat then several inches or more back a small resonator. I would love to get rid of the small pre-cat that is so close to the small resonator to get better exhaust flow.
