That type of manifold has probably 20-30 different names but they seem to be all the same. *shrugs* try it out and see how it works out. Maybe they improved the welds.
Hopefully if not oh well we win some lose some :P Im hoping the extra bars added on for support will help it's longevity though. I had seen some people selling their DNP's and some had them for three years some for less. none had cracks or anything wrong with them (supposedly) and they were selling them to upgrade I'm pretty sure. I researched them to see if their prone to cracking but so far I have found nothing I'll keep looking though (or find out for myself even though Id rather not haha)

If all else fails I still have my stock one! Which now that I have removed it I think the previous owner might have ported it because the inside is very smooth <-- I have never ported a mani but would that be sign of a ported one? If so I feel kind of silly but at least the over all appeal of my engine appearance will improve some

Finally done here is how the install went.

Taking off the header I ran into no problems, Had the heat shield and header off within an hour if not less. Putting the new header on....now that's a different story. I thought putting it on was suppose to be easier sadly I was mistaken. Due to the shape of the header I could only comfortably get about five of the bolts on with a ratchet the others I had to use a small box wrench (therefore I didn't have much torque so it was a **** to tighten) Where the header and the o2 housing connects One bolt I could just not get in I swear it was impossible I tried to remove the radiator hose to have more room to work that just resulted in me losing a bit of radiator fluid no buggy :P in the end I decided not to put that one in since I couldn't get it in all the way I didn't want it shaking out and falling in my engine bay while driving. I hoped having the others tightened extra tight would prevent leaks still. Seriously I hate half assign things I tried everything the ratchet didn't fit and neither did the box wrenches and I couldn't screw it any further down with my fingers ;(

Now when it comes to the other end of the header that was relatively easier. But not easy. The ones on the end were cake and all the ones on the bottom. But the two or three on top were so hard! I just hope I got them tight enough. One nut went missing so as you can see in the pic the one on the far left has no nut. Ill be soon fixing that next time I take a trip off campus.

MY hands were literally bleeding when I finished haha.

Ok so the start up. My car started up just as usual with it's long start haha and I was pretty much pleased. If you pat the gas in the low rpms it has a raspy sort of lawnmower sound which I didn't like to much but.... Then I took her for a spin. It is so much louder and it sounds great especially in the High rpms. I don't think I have any leaks because honestly it seemed to pick up faster than usual in those high rpms So I might have gained some minor torque nothing to brag about but my pick up didn't get worse so I'm happy. Plus my engine bay looks sexy now After the spin I took a gander at the pipes and now they have a very very light golden tint which actually looks awesome!

Now lets just hope they don't crack!!

Difficulty 6/10 (because of the how crappy putting it back on was if it wasn't for that probably a 4 if not less)

Product satisfaction for now... 8/10 1 because nothing's perfect and the other point because of the unattractive raspy sound when driving below 3000

HERE IS A PIC!!! Used my camera phone didn't have my dslr with me ;P

Did you try a crows foot wrench to get that bolt on. Over torquing the other bolts to compensate for missing one is a bad idea.

It just compresses the gasket too much and creates a better chance for leaking in the future.

Oh dang Id hate for that to happen. I hope I didn't torque them to much it was mostly with a box wrench so i might have gotten lucky. As for the crows foot wrench no I don't have one sadly. I don't think I have used one of those before might that work?

Crows foot wrenches are especially good for these type of applications. Take a look at one to see if it would work...

Mr Gasket works. If the end holes were that far off, you may have had it flipped backwards. Also you have to enlarge the last hole on either end.

I think it was just a lemon. All the wholes lined up perfect for the bolts in the middle but the ones on the very end are much to short. Plus there is really only one way to put a gasket on where those ridges push outward on the openings that side has to face away from the header. (regardless of that i did try all ways possible it seemed nothing would work unless i cut off the pieces of metal at the end, the ones on the end aren't even really holes their u shaped cuts that just slide down over the bolt)

I just used my old gaskets though they seemed to be in decent enough condition :P

Sadly lancershop won't refund my money because I had taken it out of the package

You make out with the crows foot wrench? Or you just say screw it?

and I guess your lucks the gasket I got line up fine in the middle but the bolts on both end sides were an inch to far from their designated places.
Good luck on.running the DNP. I have never been a fan... All the ones that I have ce into contavt with were almost as bad as the Megan's, just more expensive

It didn't have holes to enlarge it was slits on the ends of it (basically if there was no bolts in the middle you could slide it down onto the end bolts. Thats how the end is shaped)

And I tried every way I could think of it wasn't a placement issue but more of the length from one end to the other it was obviously not going to fit when I lined it up I just thought Id try anyways :/ Thanks for the tip though well appreciated.
