I keep going back and fourth on this issue, any help would be appreciated:

I just had Nissan drop a new long block in my car. I’ve put 1000 miles on it so far. I purchased a Cattman mine Y-pipe thinking that I should not put headers on right now because the engine is new. Was this the right choice? I was worried about the headers negatively affecting the new engine or voiding the warranty. I have not installed the y-pipe and really want to order the headers. Can someone help me what with what you think I should do?
Thanks

 

Headers for sure....shoulda gone with Hotshots since they are only $550 shipped iirc...unless you got the dough for Cattmans which are $850 or more....

Headers will not give the engine any problems unless you install them incorrectly

 

Right, but what I am trying to figure out is should I worry about the engine being new or voiding my warranty?

 

I missed this part of your response.

 

Headers will only void your warranty if Nissan can prove that the headers caused whatever damage it is you're seeking a warranty claim for. More legal information on this is in the FAQs.

 

Did you decide to get headers yet yourself?

 

I don't think you should worry about either one....the engine being new should have nothing to do with the headers...and like puppet said, you should only worry about voiding your warranty if your scared that your dealer can PROVE the headers itself caused the problem....but like I said earlier, headers installed correctly should not give any problems...

 

Thanks....

 

I would think the headers are better just because it eliminates the Pre-Cats. Last I heard some engine failures are a result of Pre-Cat failure, where the Pre-Cat material gets sucked back into the engine.

I would want those Pre-Cats off the car ASAP.

 

how are the hotshots compared to the cattmans?

 

Their awesome....

 

THats what i did, i had my longblock replaced..

THen i had them install the CATTMAN gen 2's and exhaust system ASAP, because my precats were already broken up (2nd time).

BYE BYE $hitty precats. Screw warranty, i have the 7 years 160,000 extended, but i will NOT keep going back to replace precats every 40,000KMS

 

The only thing holding me back is the engine being new. Knowing my luck I will install the headers and wind up having to take the car back in because of a problem and them telling me they can’t diagnose the car properly with the headers on. They tried to do that with the CAI I have on before they swapped my long block.

Anyway do you need to get an air fuel controller like Apexi when you install headers?

 

Wait so you had the dealer install the Cattman headers? Why did they replace your engine?

 

It depends your AF after the install.... every car is different.

 

$550 shipped? where from? i am defiantly goign to jump on this deal.

 

Power: ??? No one has done a direct Dyno compairison, however, on different cars, the HotShots have posted very similar results.

Reliability: The Hotshots have been on members cars for over a year and no problems thus far. BlackbirdVQ ran HotShots for over 2 years on his Sentra with no problems. Cattman, I dont doubt the reliability, he does good work.


Price: Well there is no compairing them in that department. HotShot-$550(shipped from SCO), Cattman-$850-$1,000(+Shipping charges).

 

That is what I thought, but wouldn't that definitely void a warranty if you install an AFC?

 

Grow a sac... to your warranty..

My warranty is great.. It doesn't require the work to be don at or by Nissan.

 

What the hell are you talking about “Grow a Sac”? Why would I want to purposely void a warranty so that a repair might not be covered? The dealer I go to has done nothing wrong and has repaired my car when needed with out giving me too much of a hassle. I'm just trying to cover all ends.

 

. So when were you planning on doing so, if not now when?

I would put them on 1st chance I got.


No negative effect on engine. The warranty stuff all relies on your personal Nissan dealership. My guys are cool, they said as long as I could get rid of the CEL(extend o2's or use a sim) they were cool with them there. But you don't use my dealership so you will need to answer this on your own, as there could be hundreds of opinions on here. Technically, but sometimes it doesn't work like this...but law states that the dealership has to prove that the headers have caused whatever problem you are having. And most dealerships will blame them regardless if they are to blame or not, simply because they are not OEM.


Sell the y-pipe, and get the headers...

 

I was planning on putting them on after my warranty ended. I am at 41000 miles and was going to wait until then. But then again if it is true about parts of the pre-cat getting into the engine when they go bad, then the sooner the better.

The reason I am acting soo precautious is because I am tired of dealing with problems with a car I just bought last December. It took me 3 months to get them to replace the engine. Thanks for your advice.

 

Does that mean you want me to --> ?

 

Are you asking me if I want you to leave? You love those Smilies, don’t you?

 

My engine was replaced because my VQ35DE was burning mASSIVE OIL for 9 months. Up to 2L of oil in 2000kms.

Finally replaced it. My dealer installed my stillen brakes, Cattman exhaust, Polyurethane ES mounts and ttranny, new clutch, cattman headers, everything...

The best part is that its NOT much more than i would pay outside as I have a very good relationship with my dealer. They even installed the O2 simulator as well. I supply all parts though.

The headers were a GREAT addition, as it is power you can REALLY feel.. And it hits in the midrange and up too.

Cattman is a great company. Brian is great to deal with and very indepth guy.
