I am considering getting a cattman y pipe for my car in the future (probably a year or 2) but I have a few questions.

I loooked in the stickies but a few of the links are down.

Car is a 95 Maxima. I listened to all the soundclips too, just want some more info, thanks


The reason I am looking into cattman is because its been highly reccomended and ive been told you get what you pay for. I'm not 100% set on buying a new exhaust system since its not a necessity, Im mainly trying to learn a few things for the future. Thanks


1. I want a decent sounding exhaust NOT RICEY, will a cattman y pipe give a somewhat aggressive sound?

2. If i get a y pipe, do I have to change my o2 sensors? What is required to install these?

3. I dont plan on changing headers or anything else, more than likely just the y pipe and muffler.

4. Will the installation require welding?


Im sure these questions have all been asked and answered a million times, I just want to make cure of a few things.

Thanks for the help

 

2.no
3.ok your point?
4.not for y pipe

 

Sound is all opinion so I'll leave that one alone.
Why would you need to change your o2 seosnors?
No welding required.

 

i thought the same thing after i posted, im just trying to say that im not getting a full exhaust (headers, etc)

 

I read in another post that someone bought 3 new o2 sensors with their y pipe. I asked why and another member mentioned while taking the old o2 sensors out if you damaged the original ones you would need new ones.

 

I had a cattman ypipe on my old maxima and it was great.

You shouldn't have a problem getting the O2 sensors out without damage.

Ypipe alone will change the sound of your exhaust EVERY SO SLIGHTLY, no rice to it though. Slightly enough that you will barely notice it, and that anyone else not familiar with your car will not notice it at all.

No welding is required. If your car is from the north where they use salt on the roads in the winter, you will almost certainly need to have the bolts holding the ypipe to the catalytic converter cut out with a cutting torch. Being as you are in florida though, this might not be an issue for you. A four second look under the car will answer that question easily enough. If the bolts are so rusted that they are unrecognizable as bolts and they just look like little blobs of rust with no defined shape, then you will need to have them cut off.

 

thanks for the info, you think a muffler will have any effect on the noise output?

 

It will have the most effect on it definately. You've got to be careful what you get there, because some of them sound pretty bad (ricey). Honestly I hate the maxima's exhaust note for the most part, so it's hard to get a good sounding exhaust in my opinion. Best I've heard in person is the Apex'i WS which I don't believe they make anymore, and the Greddy SP. Greddy SP2 isn't bad either, but there is a brief RPM range around 2500 or so that it sounds kindof buzzy for a moment, but once you are out of that RPM range it sounds pretty good. Best I've heard a sound clip of is the Cattman.

 

thanks for the help, I appreciate it

 

just out of curiousity, what constitutes u asking these particular questions "probably a year or two" in advance? who knows wut other things happen or prices will be out in a year or two. i guess what i'm saying is get the y-pipe b4 then?? if u can of course

 

Here's my car with a Warpspeed Y-pipe and HKS Sport Exhaust. You live in Florida, just get a warpspeed Y. It's cheap, bolt-on, won't rust and it does its job. I didn't notice any increase in noise with just a Y-pipe. The muffler makes a huge difference in noise.

The HKS exhaust is deeeep, probably deeper than most maxima exhaust systems, without any ricey raspy buzzing noises.

I live in upstate NY. I am putting a highflow cat in my 99/standard tran max. Will this effect any of the o2 sensors set off any warning lights or not pass inspection now??

Any help is greatly appreciated.

 

Read some of the stickies at the top of the page and all of your questions will be answered.

 

IMO... cattman is nice, but too overpriced. look around for mandrel bent ypipes. there are a lot of places you can get one for half the price and the same quality.

 

it shouldnt. but for your car custom enterprise offers a test pipe. you should go with that. so take your car to inspection with you stock cat on, then when you pass, put on the test pipe. just keep your stock cat incase you need it because one from the factory is like 800 bucks!

i dont even think you have to worry about emissions. i went a month ago and passed with my headers, ypipe, high flow cat, and greddy sp2 cat back. i live in CT tho

 

hi-flow cats are a waste of money....i would get a y-pipe first...and as long as ur car is warm it shouldnt set off any codes for the gay NY State Inspection
