Getting ready to pack up Cattman headers/y-pipe for ceramic coating of headers and y-pipe assembly, after having wideband O2 sensor bung installed and filling/smoothing inside flange area....

 

Looks like your ready to go.

 

love the look of the y-pipe.

 

post pics after they are coated.
Who is doing the coating and what did they charge you?

 

+1 if local.

 

copycat.....haha

 

very nice wizard//

 

Coated Cattman Header Bandwagon FT?

 

Nice setup Matt!! (again)

 

ok, i have a few dumb questions for u wizard...what is the flat metal piece for on the "loop" on the headers/ypipe? and what is the purpose of the flat sheet of copper (i guess thats copper, idk)?

 

Flat piece is part of Cattman's design since the loop hangs a little lower than he/we liked. It's for protection. A skid plate so to speak.

The piece of copper is a homemade heatsink to protect the somewhat fragile wideband O2 sensor from the hot exhaust.

 

Thanks James. Those will hopefully be going on my 3.5 this summer.

 

Polydyn (polymer dynamics) is gonna do this Header/Y-pipe...unlike "The Wizard" with only his shorty headers done. I'm gonna have the entire setup coated 3000 degree F. Titanium. It'll probably cost me $200-250. But oh well, I'm reducing the underhood temps, increasing heat retention in the exhaust system (higher Velocity), and trying not to melt all that plastic **** that's close by....
Also Wizard I elected to place my wideband somewhere less congested 180 degrees opposite of you, I'll need no heat shield to protect my sensor, I've got plenty of cool air flow there. I'll post pics once I recieve the package from Polydyn and I'll show you guys what gaskets I chose over the Cattman supplied stuff that wasn't heavy duty enough for my personal taste.

 

in for said above^^^^

 

I paid close to $350 for my HPC extreme coating (inside and out), so I figured I'd do it in stages. Headers are the most important as I have an aftercooler sitting right above the front header.

Your car idles doesn't it after a boosted run??? A heatsink is never a bad thing to protect an expensive wideband O2. Also, the instructions say the sensor should be between 3oclock and 9 oclock, with 3 and 9 being the minimum. I elected to do better than the minimum. And, I don't have to worry about crap hitting it. I strategically chose that location for a reason for those who are wondering.

Regardless, looks like you have a solid plan of attack.

 

OP, I wouldn't have the patience to get those coated. I would want to put them on as soon as I got them from Cattman haha. I have this setup and I love it and you will too. Everyone compliments the sound too

 

nice looking headers, for those with the 3rd gen headers how is changing the oil?

 

oil splashes all over the skid plate

 

While I am green with envy going through this thread, something tells me none of you posters have an LTB2

 

Yeah, Wizard I read the instruction with the Innovate wideband and you're correct, but I choice maybe about a 2:30 clock angle so it's upward and seems the clear any dogs, cats or children that don't get the hell out the way. I like how you did the heat shield I just didn't want mine near that steel donut from the rear blank. Yours maybe more permanent than mine since you are a forced induction car and you monitor yours on a regular basis. I'm just using for tuning and it'll be installed and removed more than likely, the same day, as well as switched between my cars and projects.
Oh yeah I see you filled in that pipe to flange void (on the interior ) as well with some welds. I didn't want to disturb my exhaust velocity with turbulence. Can't wait to see the finished product. As for the oil draining issue I'm make a special drain tool for that...no biggie!

 

For those interested in ceramic coating, PolyDyn just gave me the quotes on the CM Headers. They quoted $220 for the Shorty headers and $150 for the y-pipe...

I have the cattman set-up, but no coating. Those (all) look very nice

 

sweet, looks good

 

I heart this thread...

 

ive got the hotshot headers on the car and not only do they look great but the power increase is great. Hows the cattman headers vs the hotshot

 

Don't know! First of all never owned any Hotshot to compare it too, and I just got my Cattman's back from being ceramic coated entirely!

 

icanhas?

 

so whatever happened after you got them coated?

 

bump??.. just stumbled upon this thread.. what happened.. ever get a dyno?

 

Not sure, but ceramic coated Gen III bandwagoner, checking in...

 

i love that............ i think im gonna have to swagger jack

 

where did you get that? what website? because cattman does not have a website currently and stillen.com doesnt have any for 4th gen maximas (97) so idk what to do....i need a y pipe because my monza exhaust isnt loud enough for me....it does sound good dont get me rong i just want more noise

 

Who are you talking to?

Cattman does have a website......... www.cattman.com
His phone number is there. He's also in the Group Deal Forum.

LOL at wanting more noise...

 

question, doesnt that almost 360 degree bend affect performance compared to regular headers for the max?...

 

IMO, no. Equal length and mandrel bent=win.

 

Even if you lose a little, equal length sound = win!

 

Lookd good!!
