Alright, after getting the P0420 code(even though I think I have it fixed now) and reading all the horror stories about how sand from the cat gets into the engine and destroys it. I'm thinking just to do some preventative work, bite the bullet, and just get the cats done. My question is, I can get a walker front cat, rear cat, and Y pipe for 685, or the same bosal setup for 665. Its only a 20 buck difference I know, but who hear has had luck with what? Someone in another thread said that they bought bosal and have had 0 problems. The car only has 126k on it, so I really don't think the cats are shot, but I really don't feel like replacing a motor. I looked into Cattman as well, and Magnaflow, but for the Magnaflow, it was 615 for just the front and rear cat, no y pipe. Am I being overly paranoid and shouldn't waste the money?

 

That's expensive for those OEM replacement parts. I would just get headers for way less and gain power too, that or at least gut the cats.

Of course those options may not be for you, maybe you wanna keep it stock?

 

OBX V2. 350 give or take $$$.


I've seen the entire cat set-up for less than that.

Lol, thanks for the link, but its my girlfriends car, and she has no desire for new headers, im actually quite positive she doesnt know what headers are. And i should have been more specific, that is the entire setup shipped, for some reason amazon changed the prices, but the final after shipping and taxes is 650. Thats for a bosal front cat, bosal rear cat and walker y pipe, plus gaskets. I did check out that page and it looks pretty cool, but i checked all the parts against amazons, and amazon came out less expensive. I figured i save some money with the catco, but not so much.

 

Now, those obx v2 for my car on the other hand.......

Well, for her car, ya, id like to keep it stock as possible. But after looking around 650 is about the best price i can find for 2 cats and the y pipe.

 

 

What is your motivation for that? It's a 2003 Maxima, so the Federal Emissions Warranty, 8 years or 80K miles, has expired in 2011.

The recommendation is to delete the pre-cats, not the main catalytic converter.

The purpose of the pre-cats is to clean the exhaust untill the car fully warms up. Once the main catalytic converter has reached operating temperature it cleans the exhaust properly.

So a car without precats has a bit dirtier than normal exhaust for about 10 minutes after starting a cold engine. The increased environmental un-friendliness is minimal. An exhaust without precats will save you money and increase the car's power. AND, because she might not be an aggressive enthusiastic driver, she might even see improved gas mileage too.
Also, so long as you keep the exhaust components after the main catalytic converter, the B-pipe resonator and muffler, if you keep them as original OEM components, the car will be just as quiet as before. There will be no introduction of any new racing sounds to the car.
Soooooooo.....

 

Well said.

 

I hear you, and what you're saying makes absolute sense and I agree with it. My girlfriend is, lets say, a bit particular. Things have to be a certain way or she freaks out. The other day, we were going to get ice cream, and the place we went to is literally less than 5 min away. Well, i didnt have my wallet with me, just some cash in my pocket. The whole way there all i heard was, you cant drive without your license! OMG, you're going to be in so much trouble, turn around and go get your license while we're close......and, well you get th

 

With that said, pony up the dough and replace all cats and the cat-back since, you know, it might be rusted.

 

I have a Maxima as well, and if im going to upgrade the headers in someones car, im going to upgrade them in my car.

 

So what's the issue with price then? Headers are cheaper than replacing pre-cats.

 

But dont i still have the issue of sucking the sand from the cat back into the motor?

 

Come on man! Grow some cohones!!!
I have not known many women who take an active interest in whats going on in the engine department. They couldn't care less where the windshield washer reservoir was or where you put the air filter......and thats on top of the engine. But underneath, where the y pipe is? No mans, or womans land The y pipe is practically invisible to anyone who doesn't understand cars. She would never know if it was replaced or not.
She will probably get greatly concerned with that yellow light in the dash, but that wont happen.

 

Not sure what you mean.

I've had headers for 110k, and 9 years. I think you're good.

 

Trust me, its been ten years, its far easier for me to spend the 600 bucks to replace everything than argue about it some point later. And if it were my car? No she would never know. Her car? She doesnt watch me, but she'll come out every so often to see whats up. So basically, im spending 600 bucks not to get into an argument.

 

This is maxima.org not relationships.org......so....

 

Yeah, we told you the best solution, whether it be financial or beneficial with respect to the car, as this is what we do. On the other hand, does Dr. Phil have a forum?

 

Dude, if you don't have any rattling and there is currently no CEL/SES light, leave it alone and worry about other things in life.

 

I have the P0430 code for the front precat. I am looking at either the Bosal or Eastern cat. Since I am only getting the P0430 code I assume thats the only cat I need to replace

 

That's what I would do if I'm not into headers.

best post ever

The dealership is for people like your girlfriend. You may want to recosider your girlfriend before it's too late. You'll be posting divorce crap later down the road.

 

hahahahaha, maybe so, we have a 50 percent divorce rate in this country right? And to NmexMax, I didn't look at pictures of the V2's until after I wrote that. When someone says headers, I think of these:



So when you said, just get headers, I was thinking I would still need the cats, and I was slightly confused.


I saw a pretty good deal on amazon for the front cat, it was a bosal and it was 277.43 with free shipping.


NmexMAX and dwapenyi, I didn't mean to give to much information, I just wanted to explain as to why I just couldn't do things a certain way. I appreciate your insight though, and I will more than likely getting those V2's for my car in another few months.


BTW, Dr. Phil does have a forum, and. it's. FANTASTIC.
