Does anyone have custom maxima headers on a 5.5 gen?
http://www.custommaxima.com/product/...s/Default.aspx
I wanted to know if anyone had these headers. It says they may have fitment issues but I am pretty sure the OBX headers have fitment issues as well. They only want 179.99 too which is a steal.

The real question is: do the Custom Maxima headers make nearly as much power as the Cattman headers? If they make 80% of the power that Cattmans do at 20% of the cost, that sounds like a bargain to me.

Yeah, don't buy them... They're "shorty" headers and won't produce the same gains as Cattman or OBX, which are both the long tube style... just do it right the first time or you'll regret it...

Cattmans website is bad, you need to call. The headers have excellent fitment but are very expensive.
OBX headers are a lot cheaper but many people need to cut or modify small parts.
I have OBX headers.
Hot Shot > Cattman > OBX > other.

How's OBX's website.....Hahahahahahahaha......buy an extra flex section and keep a exhaust specialist close by, cause you'll need him/her real soon!
No Cattman's website has never been updated in a while but that's hasn't slowed the progress either.....I think it's amazing how well Cattman does thru forums and word of mouth....he products are for real!

How crappy can they be i mean if its look who really cares [ITS UNDER THE HOOD ], I want to see some dyno on this product .
Maybe someone's pre catts mite need to be changed and this could be a cheap solution and a little extra hp would be ok

That's like telling your date, "Yeah, I wear ratty old skid-marked underwear. But it's OK because its under my pants."

In that case, I guess blown head gaskets and misfires aren't a problem either. Those are under the hood and you don't see them.

Their not custom maxima headers any way thier MimoUSA sport {some sh** like that] they get rid of the pre cats and its more cost effective then buying new pre cats if their going out and you can gain a little power at the same time.

You get what u pay for, end of story. They're only 180, buy them and impress us with your overwhelming gains.

Honestly man, these threads are a guilty pleasure of mine, just for the pure entertainment factor. It's like being in HS and arguing why Georgi is as good Ketel One. " So what it tastes like donkey ****?! It's $10 for a 5 gallon bucket and you get f'ed up!"

I was hoping since you dont have headers you would try them out for us.
and do a dyno i'm sure you wont get amazing results but then again you never know

, ya your'e right some folk just like talking.....Only about $850, but these Custom Maxima (cme) are so super cheap and I would take a chance with them if I had an extra 5th/5.5th Gen to experiment with! They do make more power than stock, but they don't fit anything like Cattman's (CM)!!!!!! There was a flange not installed correctly @ the rear header collector flange.....
It wont cause any of those things im not saying that you would gain huge amount of power a lot of people doubted the obx v2's and look about everybody's got them now .

I'm sure someone will try them real soon! I hope I don't have to go get another 5.5th Gen just for that! I've got plenty of performance parts for the 5/5.5th gen....so hooking that up wouldn't be a real challenge!

No, they're not like OEM exhaust manifold which have precats! I know someone here in Houston w/ an I35 and the only bad thing was the fitment.....it was off slightly!
There was a flange not installed correctly @ the rear header collector flange.....
I'm sure you can get at 10-15 whp once it's installed correctly!

That and a 3' would be a good combo maybe cuz to go full cat man im goin to have to spend at lest around 2 grand. And i dont know if i want to go all out with mods like i did with my 95 . Try to keep the budget low the 5th gen is my commuter.

I would use the (cme) headers, stock intake or SRI, highflow cat, 2.25"-2.5" custom bpipe and OEM Rear Muffler.....

2. I HAVE headers...just didn't install them yet.
3. The aforementioned headers I have are not Custom Maxima.
Dont know why I numbered that...
It all comes down to the almighty dollar. The way I see it, if you're going through the trouble to install headers or to have them installed, either way, you might as well get the most for your buck/effort and put something that will yield the most gains.

i have those headers on my I35. yes, the fitment is not good on the rear flange it has to be cut off, turned a little and welded back on. and the y-pipe will not sit straight. it will be slanted towards the passenger side. honestly, i took the crappy way out and had a local muffler shop but some bad bends in it. but if you fix the flange issue and have a good welding shop fix the y-pipe to fit right, you'll save a lot of money and still see power gains. get these headers, the y-pipe fixed, an o2 simulator and you'll have no problems. putting a little bit of work into these headers imo is more cost effecient instead of buying cattman headers. no i don't have a dyno to show power gains and compare to cattman, but i this will remove precats and will give you more power vs stock headers. i also have a test pipe on my car.
i only have 1 close up of the flange

5.5 gen auto maxima vs I35

From everything I've heard, it can be surmised that it's not only fitment that is horrible, but build quality and design are extremely sub-par. At least with OBX you're getting a product of decent quality and design, and nothing a little crossmember grinding won't fix.
If you can't afford Cattman headers (which, incidentally, are amazing), at least opt to go the OBX route. Stay away from custommaxima exhaust products!

maybe custommaxima headers's don't have the best quality, but to me they seem pretty good. plus, if i can put some work into them and save some money. why not? i know people go crazy over cattman quality and fitment etc. but im not going to have my I35 for years to come so i chose to put on cheaper headers and make them fit. plus i can't justify spending so much money on cattman headers. i'm willing to bet that an auto 5.5 gen with the same mods as me and cattman headers won't be faster than me

The way I see it is a little more simplified: don't get custommaxima headers because they suck. It really is as straightforward as that.

What is that 1 5/8"?!
You do realize that the longer the primary's the better?
VIDEO! Please? This is gonna be funny.

From what im hearing thier are only two minor fixs the custommaxima headers aka {MimoUSA sport} need and for the price really is not bad at all.
since must of us orgers are DIYer's i dont see it being a big deal one guy i talked to on the org got them and he said that rear bracket that hooks to the header they charger him all of 40 dollars to fix and it being a two peace design easy to to hook up ..
