So first off I am obviously not a mechanic(disclaimer lmao). I have had several cars in my time and have raced drifted and modified several cars and all my knowledge is based off experience. This is my first CVT car(I'm all about the manual). With that said, I know the CVT can't handle too much increased power for the car. So my original plan is to get a body kit/wheels/coils(eventually AirRex suspension)/headlights&taillights so a bunch of cosmentic car stuff. However, I do plan on getting the ypipe and exhausts and possible an intake. My question is, IF and this is an IF how well will the CVT communicate with the mods if I decided to go with ypipe/exhaust(specifically racingline ypipe & motordyne exhaust), stillen intake, cxj performance throttle body/manifold spacers/BOP? I ask because apparently the ypipe alone adds roughly 10-15hp and the CXJ parts help add 10hp? the intake maybe more like 2-5hp apparently on this car intakes arent that much of a gain more for sound compared to other cars. So just with that, thats roughly 22-27hp gain on the car. and thats with the 3 mods I mentioned so far. So how will the CVT react to those mods over time? Any one have issues with response to throwing codes etc?? Or would I be in a position that those would be the most mods can do anything more would just crap out the CVT? Any assistance would be greatly appreciated!

 

I think most have a similar setup who have exhaust work done on their car and haven't had any problems so you should be fine. My only suggestion would be to stick with all motordyne for the ypipe as well since you're alreasy getting thr catback. You'll have less drone and won't require any modifications unlike the RL ypipe which will have to be shortened by an inch or so to allow the motordyne catback to bolt up properly.

 

Good advice on the exhaust. Also, stick with the OEM intake. That is unless you just want the increase in sound. I recently took my Stillen intake off, put the OEM back in with a drop in K&N, car definitely feels more responsive off the line now.

 

Thanks for the replies! I figured as much for majority of the mods. I eventually plan on getting an actual intake because I love the increased sound. However, I don't plan on that anytime soon, would like to keep my warranty on this car and once I add an intake or get rid of the cats I void warranty....so like you said for now I plan on doing a drop in K&N filter and getting the exhaust plan on going with either the highflow cat ypipe or resonator ypipe. I do like the sound of motordyne. But that price tho lol. I plan on going with Motordyne ypipe because I have a guy hear who'll put on magnaflows for REALLY cheap. He customized the exhaust on my last car. So I plan on going the cheap route first with motordyne ypipe and magnaflow setup cat-back(*quoted me $145 for EVERYTHING, original price though is $550 so its a steal lol). That way I can save up for the Motordyne exhaust. I have bunch of custom work stuff planned out so money has been tight lol...........Anyways the reason why I ask is because I've only seen people dyno the 7gen stock with estimated 225-230whp. But after mods I haven't seen anyone else dyno and if they have dyno'd they mentioned that the numbers were so out of whack they didn't even bother to post what they got. So has anyone dyno'd their 7gen after all the mods mentioned above? If so how did the CVT handle after the tune and what were your numbers?

 

Nobody has gotten consistent results because of the CVT. I haven't heard of anyone actually having success.

 

Ok I figured as much. I just thought we would at least have an estimated range for ppl to be like well its so inconsistant that the range is like 245whp-275whp. And with all the research and stuff apparently mods with this car you would need a tune....like I was thinking about the K&N drop-in but apparently you have to constantly reset or throw your OEM filter back in. So I know the ypipe/catback should be ok without a tune but that just means thats all i can do. So it'll have to be buy the intake/BOP/pulley(<--not sure about this one though from what I've been hearing). So once I install all that I can take it to go get tuned. Basically, it looks like nothing but exhaust for now.......back off to my original plan to making her look pretty=).

 

I haven't heard anything about drop in K&Ns causing codes to be thrown, anybody else?

 

I put in a drop in K&N over a month ago. Definitely feel a bit more power on the butt dyno, no codes though.

 

Ive had a few cel lights with my k&n drop in, but that is for MAF purposes ONLY. I love my k&n drop in and have had no issues with it directly whatsoever. Its much quieter and i love it. I think i need a new maf here shortly. I think with these oiled filters you should clean the maf regularly.

 

oh really? well i recently joined a maxima facebook page for a bunch of other ppl with their 7gens and several have said that for a few weeks the K&N will work but then they feel lose of power and a few other issues and the car wouldnt act right again until the OEM filter was put back in or until the car was tuned=/......hmmmm

 

I've had no issues with the drop in K&N.

 

You are wasting your hard earned money on any kind of "performance" drop in air filter. Do some research on the www. Paper filters perform just as well....amd clean the air beyter for your engine.

ANY kind of air intake will sound good, but also be detrimental to engine performance unless it is a true cold air intake. To my knowledge, the only one around is the stock intake. No one has been smart enough to mimic it yet.

 

I used a Jim Wolf Technology Pop Charger & a K&N drop in my 4th gen for most of its 230k plus miles. I never had any issues with the engine because of these filters & it saved me money over buying paper filters.

 

I'll accept the 15 dollar cost + convenience once a year of a paper filter compared to the time, maintenance and cost required of a K&N.

 

I like the convenience of not having to do anything for 50,000 miles.

The Magnusson-Moss Warranty Act states the following in regards to any Mods you apply to your vehicle:

Will using 'aftermarket' or recycled parts void my warranty?

 

Bro tell me you're from NJ, cause if you are please give me this guy's number. The only thing stopping me from a motordyne set up is the $1700. And then getting it all installed for $100 more. So K&N cold air intakes don't really do much? Are people only getting the filter now?

 

The intakes don't do much for our cars & non are true cold air intakes. The only cold air intake for our cars is the stock one. The aftermarket intakes will give your car an aggressive intake note. If you like the sound, go for it. Just don't expect any gains. If anything the car will feel a little bogged down off the line.

 

That's good to know! All I did was go off my last conversation with the Nissan dealership service manager when I would get my car worked on and had mods. Really all they did though was oil change since it was $12.95=D. Had an issue with a noise on my Sentra and they said they couldn't cover anything on the engine since the engine was modded(Injen CAI & Universal Oil Catch Can) and was lowered on coils(BC Racing). Which luckily for me it was the diff that was an issue warranty covered it. Been in Japan too long and there you can't modify unless you go through the dealership and if you do it yourself warranty was voided so I assumed it was the same since they brought that up....I know I assumed so next time I'll do my research. Thanks!

But even with that said, I won't do an intake anytime soon. Like others have mentioned the intake won't do much for the car besides more aggressive sound. Only thing I have heard is that ppl are doing the K&N drop-in filter which have had mixed reviews. Some say after a few weeks the car needs a reset or OEM reinstalled, while others say they have had no issues. The reason for me getting it is my original plan is to go more looks since the car isn't performance friendly. Which for now is ok with me. If I wanted performance I would have gotten a stick shift. I just wanted a small performance increased.....don't want to just build looks with stock performance.....exhaust(ypipe&catback)/intake(eventually)/manifold&intake spacers.....and good tires once I get nice wheels for it=). Thats really all I plan on for performance.

 

Sorry bro, I'm in Texas=/. I want the motordyne exhaust too, but I plan on importing some stuff from Japan that will be kinda pricey so I have to save up for the exhaust, prolly be another tax season purchase haha. As for the intake our cars won't have much of a gain BUT since it is an aftermarket intake that will allow more air-flow it would be considered our short-ram intake that prolly wouldnt make more then 2-4whp. Which to me isn't worth $300. My Spec V Injen FULL CAI at least gained 8-12whp after tune which can justify $250 on it and it sounded really aggressive for a Sentra. but purchasing a $300 intake that will only gain est 2-4....you will most likely see those same gains in the $50 K&N drop filter=/. So yah you would mostly be buying for sound which would be droned out once you put the motordyne exhaust on haha. This info is based off of speculation no mechanical info to prove the facts so if I'm wrong someone please chip in=).

 

Thanks for the response! You and 1996blackmax just saved me $300. I am just going to get the $50 drop filter.
