Fitment Questions on headers and piping
And why wouldn't they fit? I thought the 3.5 Altima and our 6 gens have the same Chassis and engine set up???

Yeah these have been installed on a few rides... some parts are a bit tricky... some trimming here and there... They do fit, but with a little work.
And I know they are a lot cheaper than the Cattman headers, but do yourself a favor and spend a little more for them, since they are made in the USA by a great guy, while these are just some Chinese knock-offs.

Thanks guys for the info... I looked over Cattmans prices and they're wayyyyy out of my price range. I found a couple of set ups ranging from $75 to $300 for everything, and Cattmans price is $1205.00



Even if I had to weld or bend these to fit properly, I'd still save up to $700.00....
What do you guys think??
well #1 the ebay headers your showing poics of arent even dyno proven for anything infact i was reding about a dude with an altima that used some garbage like that and dynoed lower than his baseline so id go with everyone else and support brian and buy some proven products

[QUOTE=BigRell1981;6967662]Good Morning guys, Do any of you know if this will fit our 6th gens... The kit is for 06 Altima 3.5 SER... If so, are there any extra parts or problems I should know about before I make a purchase???
I sent you a PM.

Go Cattman. Stay clear of chinese headers. The CEL stays off if you have O2 sensors before and after the cats. The ECU wants to make sure that the cat is working and thats how they do it.
... And then they're people with other headers that are happy as well..But honestly, I think that Cattmans' headers and Y-pipe are over priced... With the $1200.00 that I would spend on Cattman products, I could get my headers, Y-pipe, LED Taillights, 07-08 Back Bumper, 07-08 spoiler and still have $360.00 left over...
True enough... but in this case, you really do get what you paid for... of course I'm a fan. I have Brian's headers and y-pipe... both mods together have given me more go than all my other mods combined...
I know a couple of people that have this headers and they love it, i just got mines last week and i'm planing to install them in the next couple of weeks, i know that cattman make some good products but $1200 is way to costly right now
You could get Brian's headers and y-pipe with cat, and a Greddy SP2 knock-off exhaust... that'd lower the price by quite a bit...

I have ebay headers no problem, no cel, runnin o2 simulators no complaints so does a few members on here. Never had to trim anything just actually brought a resonator to tone down abit and factory gaskets 11$ thats it. They are all the same thing to me just my 2cents. The only situation Ive noticed on some 6gens that these headers were for Altima ser which most were manual so the clearence for a 6gen max with a 6sp,4sp auto,and CVT would not have cleareance issue at all. But a 5sp Auto the cleareance is close to starter because of its location,and also just have to weld the egr pipe since it doesnt have fittin but this is not major issue simple task.. the quality is good. So if your installer knows what he's doin you shouldnt have a problem. My car runs great and performs well . Just here to give some input but its your choice and not expensive like the other route Cattman is a great product but for some its out of our price range.

i tried these same ebay headers and had all sorts of fitment issues, not worth the trouble...better off getting cattman, at least you know you wont have issues and in the long run is better worth it.
