As the title says, my friend has an 03 Maxima. He ordered these Headers and Y-pipe.
http://www.custommaxima.com/product/...s/Default.aspx

He is now questioning whether or not they will fit on his car. Since I do not know the answer to that question I figured I would post a thread and see what you guys think. Any suggestions on if it will fit?

They look just like the SS auto shorty headers and with them being short and straight Y pipe there should be zero fitment issues.

Honestly, while most everyone here will hate on them, if you don't care about a big perf. gain, but want to get rid of the engine killing stock exhaust, it's a great, cheap, replacement.

 

man, this question has seriously been answered probebly once a month for the past 4yrs.... headers fit from 95-03, they all bolt to teh block.... where is SLCpunk with that pic with the dog covering his ears???

 

Once a month? I was gonna say once a week

 

i cant see how the search didnt work... just type in headers, search complete

 

Well.. They will fit the block. However on a 5th gen they MIGHT hit the motor mounts imo. They don't look to have that good curve to avoid the motor mounts that the cattman obx v2+ have.Anyways, definitely been answered before.

 

Take back, I missed how short they were. Shouldn't have fitment issues. Hopefully.

 

I'm glad someone finally bought some!!!! It should fit better than the OBX's originally did.....

 

I realize that just about anything will flow better than stock stuff, and that these are cheap, but is it really worth the minimal gains? I'm not hating or anything... just a serious question... I don't have headers yet, but EVERYTHING I've read says that the "shorty" headers just don't really do much...

 

Just getting rid of the precats is most of the gain.

 

Oh...oh no.

Not again.

Please God.

 

Removing precats will see good gains. But at the same time, having smoother bends and transitions will increase the scavenging effect and will net some gains, too. The sharp bends in the collectors in these headers seem like they'd kind of botch the flow of the exhaust a little.

It's basic inertia, really...

 

but...only in theory, dont shorter length headers tend to produce more lowend and longer length headers tend to produce more top end? so there for on a Dyno which is run in 4th and very fast not show as high of numbers actually gained but a 1/4mi would?

 

I put the SS auto ones (identical to these) on my old 5.5 to get rid of the stock exhaust after nissan's brilliant ******** killed the engine with their failtacular design and parts..anyway...for what they cost, you can't go wrong. The flex pipe is weak, so if your mounts are crap, it will break it after a while. But even welding in a strong piece is still pretty cheap over all. The car was definitely faster.

Also, **** emission laws. Without that useless crap, we wouldn't even being having issues.

 

Me and a buddy with same mods. His 6mt max had shorty stillen headers. Mine had obx 3.5 headers. He had spacers but no vias and I had vias no spacers. I SLOWLY SLOWLY gained on him. Just deleting your precats is almost 75% gain imo.

I'd however always say go longer for better flow. But if you find a STEAL on shortys, i'd get them.

 

My neighbor wants me to install some CustomMaxima headers on her car now!!!!!
I can't resist her!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! She makes me so freakin weak I'll do it for free....Lord help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

DAME!!!! YOUR LUCKY..

 

lulz

 

Man I would too by the way you need some help only if she is going to be there...

 

Rofl and what on earth gave HER the idea to mod a max??? :P

 

LMAO!!! there it is... post the other pic with the dog covering his ears lmao!!!

 

i have a video on a disc with my friend (4th gen) auto dynoing with these headers and iirc he pulled 189whp and 182tq, just found that dvd 2 days ago after all the years, im sure there will be gains... good gains too

 

oh lord!!! what a neighbor, i'd even tell her those the best headers ive ever seen in life, then have a friendly race and let her win, the long run win is way better, OML id build a whole car for her

 

JUST JOKING GUYS!!!!......She a whole lotta woman though, & fine as can be.....She could sit on my face anyday!

 

OMMFG LMAO!!!

 

lmmfao whoaaaaa

 

Just curious. Has anyone just deleted the precat and ran a straight pipe?And would I be able to pass emissions? Sure I would but just asking.

 

People have just gutted their pre-cats and driven and their butt dyno claims to give them power.
However the thoguht of running such a small area to a large hollow area with the collectors so short just seems pointless iimo.
