Whats got two thumbs and a new set of Cattman headers?

<-- This guy.

 

Got mine today !!! Can't wait to get em installed!

 

On that list for the new batch. Motor swap and a few other goodies are awaiting these headers.. Cant wait

 

Hey Guys you might wanna install those headers with some copper gaskets (between the exhaust manifold and the ypipe) and call it the day... SCE gaskets p/n 4220 available from Summit Racing, etc

http://www.scegaskets.com/Pro-Copper...-p6630142.html

 

Are the gaskets it comes with not good enough?

Also I read that there is supposed to be some type of insulation included for a coolant hose. I hope i searched the package well enough but I did not see this. Anyone else missing this?

 

Yes I didn't see the insulation in my box either . I will probably call Brian on Tuesday.

 

One time use only..while the 4220 are bulletproof reuseable copper gaskets! You'll see when you get them...they're good but not SS (Like of the Oems) nor copper!

 

Your bottleneck is that your running 2.25" header collectors/y-extensions...when you should be running a 2.5" header collector and a 3" y-pipe with 3" exhuast....GET ON IT NOW!!!!!!!!!!!

 

My Cattman headers (Gen 3)are usings a beautifully designed 2.25 header collectors and you really believe this is the absolute bottle neck?

 

is there still anyway to get these headers? and what about a full catman exhaust?

 

The list for the second batch is still up. I believe Brian needs 3 more people to start production. Give him a call, very friendly and will answer all of your questions. 1-800-759-9920

 

Got mine Friday night! I'm just waiting for more people to order the catback system so I can get everything installed and tuned at the same time!

 

For a normal bolt-on setup, no. For someone who wants to squeeze everything NA, then yes.

 

Who's going to make me a set-up like that in 3" though.

 

What are you guys doing with the rear O2 sensors? I wrapped mine in foil and used stainless zip ties to strap them to the cross member under the engine. No CELs with several drive cycles.

 

I installed a O2 sim

 

My secondaries are plugged into my primary ports and I only have primary codes because they are completely unplugged. So try and just leave them dangling somewhere but still plugged in.

 

Any word on where were at for the next batch? I thought we were close. That y-pipe thread keeps calling for me.....

 

The last time I heard, Brian needed 3 people to begin production.

 

Might be getting on this in less than a month if everything goes well...and hoping I get the Great fitment I have heard from plenty of people, but I just wonder WTF happened on the last Batch....some say good some say otherwise.....but I'll see in a couple of weeks hoping I dont miss another chance at these....

 

Don't worry, I think you can still get in with this upcoming batch. I was wondering about the fitment issues of the last batch too. I hope this batch won't have any issues. I'm just hoping there won't be any problems finding O2 sims.

 

Fitment was perfect. The real b_tch was getting the old stuff off. Nice sound. A little buzzy until warmed up. Very pleased overall but would not want to go through the process again of removing the stock stuff.

 

So you were on the last batch...with no problems of install....

 

I installed a dual O2 sim and wrapped my secondaries and stuffed them under the battery tray!

 

So you're talking possible race headers if you wanna squeeze out everything.....So do you know of a Maxima with this or are you just comparing it to the header design of the Z crowd? You got headers on your GTP?

 

Interesting that I did not install my O2 sim but I am also not getting an CELs either.

 

Guess you are one of the lucky ones how many miles has it been....

 

There's # 3.

 

I hope I can be a lucky one but probably will be on the 02 stimulator...

 

I've logged a few hundred miles..........runs like a champ. No CEL.....no complaints.........no more money

 

Just got OT at work so I should be calling Brian on Monday or Tuesday to get on the next batch......

 

Check and retorque all your hardware....after a few heat cycles things loosen up!

 

Just called today Lucky #7, on the list only 3 more to get this rolling...

 

Get Em, While You Can...

 

 

I guess the previous group of headers got everthing straight regarding the flange? I haven't seen any whining so they must have straightened out their issues?

 

Majority just had to make holes a little bigger I can't wait to get mine in my possession, like Hell Yeah...finally....

 

Come on peoples....

 

I finally got around to installing mine yesterday after work (finished around 3:00 am) but sure enough I had to widen 3 holes on each header which was a little annoying but not a big deal. I did the job on jackstands which made things a little more difficult but now that I have done the job once I know I could do it again in much less time. I can definitely feel the extra power and I love the sound of headers with the stock catback (quiet growl). Now I just need to find someone who is selling O2 sims (o2sim.com is currently not taking orders)

 

Damn 3 in the morning what time did you start at....
