I installed a new warpspeed Y pipe and a cat that came with it almost two years ago. This setup was almost as quiet as stock for a long time.

A couple of months ago the exhaust started running louder I have since installed a new Walker B-Pipe and muffler with no real change. There is a vibrating sound or drone that is most noticable at startup or under hard acceleration. The noise/ vibration appears to be coming from the cat or flex pipe area but those both appear to be in very good shape and all the connections appear to be tight. I can feel the vibration in the floor of the vehicle. I am thinking of trying to wrap the flex section to see if that quiets it down.

Does this sound like it's Bees in the can? Does Bees in a can occur after two years? Can anyone give me some advise on how to resolve this problem. Thanks in advance and yes I did a search of bees in the can but could not find out what that really means.

 

i don't think the bees thing is a symptom of something that's gone wrong. i think it's more of an inherent sound assiciated with certain exhaust systems and setups... that ugly, raspy, two-stroke, chainsaw sound given off by almost every Honda that's got a shiney muffler.

your's sounds like something's failed.

have you been under the car? have you checked the bolts that secure the cat heat shields? if the shields are loose they'll rattle and vibrate like crazy.

while your under there, start the car and pinpoint the source.

 

Thanks, but it does not sound like a two stroke Honda it's more of a deeper droning noise. I've been under the car and it's not the Cat heat shield because I removed it. I've checked the connections and everything seems solid, no leaks. Maybe the flex section has somehow expanded or deteriorated such that it is now noisier. That is why I will probably try exhaust wrap to see if it quiets down. I'm still trying to find out what is bees in a can is and what causes it.

 

wally i need to hear what u r talking about.... btw if you wrap the flex section its only gonna cause it to rot faster in the winter...

 

that is true about the wrap. my friend did it and his **** rusted to nothing. and i don't think u have the bee's in a can. it would sound like a honda with a cherry bomb on it.
it might have jus fell apart in the inside of the cat. i hope it didn't, but that's what it sounds like!

 

I dont think u have bees....post video if you like though.

 

One thing you should check that you may not just see right away is the flexpipe, the outside may look fine but the actual flexpipe behind the stainless steel mesh can break.
Start the car up and put your hand around the flexpipe and see if its leaking that would account for the change in sound.

 

i just baught a warpspeed y pipe too..n i got a 2.5 custom piping after that..no cat no res. and it sounds just like as described..ill try to post a video and show u guys..maby i just need a better muffler?

 

arrite i finally got a video..now..can any 1 tell me wtf is wrong with my exhaust..i think its the muffler..could be the y pipe that add the raspy honda sound ..oh yea the muffler is a..darn whats the name...Xlerator.
hears the link to my video.

Yes that is definitely the bees in a can sound.

 

Mine does not sound anywhere near as terrible as nishansmaxima. My exhaust sounds great compared to that. Sorry man that sounds ricy, you probably need a resonator.

I was only going to wrap the flex section temporarily just to see if it is the cause of my problem.

My warpspeed flex section only has mesh, it does not have a lining inside of it. Is that normal? I have checked for leaks by running my hand near the pipe, nothing obvious. It's definetly the cat of y-pipe area causing the noise.

 

damn...u guys know how i can get rid of this sound other then a res.?

 

Wow you need a resonator badly. Your set-up sounds like a POS dirt bike. To the OP don't wrap the flex section, just live with the fact that you have the "bees in can sound". I have it slightly but I don't care, it isn't that bad.

 

im gonna cry now....damn man i didnt want this to happen!

 

That's bees in a can?! I thought 'bees in a can' was solved by bracing that flex section so it doesn't vibrate as much.

3rd post is what I thought people refered to as 'bees in a can' in a maxima application:

holy shiet....its beez buddy. lots of them too. Do you have a hole in the piping/muffler by chance.?

 

damn and i thought my setup had a bad bees sound...
i wrapped my flex...and it didnt do much...maybe a 10% reduction in the buzzined...i welded on a nice big resonator and it solved a lot of my problems ...i believe the the buzzing comes from the flex partially and the fact that it isn't a equal length y pipe.

 

Thanks for the feedback. My setup worked great for almost two years. I''m starting to think it's not exhaust leaking through the flex section or anywhere else but that it is a vibration problem. Think I'll see if I can provide better support for the flex section or y-pipe. If anyone has any ideas how I can accomplish that feel free to chime in.

 

just go to an exhaust shop and them weld on another hanger..thats what i did...it was like $10

 

Did that help eliminate the bees noise?

 

It did for my bro's Maxima

 

you sure you don't have a horrible exhaust leak - like even a big crack? my old y-pipe finally gave up the ghost a week or two ago. the runner that comes from the front bank has a significant crack in it. noise is most noticeable under moderate to heavy accleration. not very noticeable at idle.

 

im pretty sure i dont have any cracks or leaks in it..i just got the thing 2 weeks ago! they said its the new spiral flex section to eliminate the bees in a can noise..i called up the owner of the company n let him hear it n he claimed its not that...i have no idea wat to do now..i guess my only option is to get a better muffler and slap on a res.

 

correction, a cherry bomb is what helps eliminate the "bees in a can" sound

and I really wish people would stop generalizing this with hondas, cause there are plenty of fords (foci, 6 cyl mustangs) nissan (sentras, 200sx, 240s) and Subarus, and many more makes of cars around here with the same distaste for a decent sounding vehicle.

oh and Nopike...IMHO it just sounds like your muffler has lost some baffling and needs to be replaced. most of the time a section falls apart in there and starts vibrating up against another section of the muffler.

good luck

 

alright this is what i would do before you start throwing around money...unless your rich just humor me.

undo the muffler at the flange where it connects to the B pipe. rev it up and see how bad the bees are. if they are bad bolt the muffler back on and take off the cat and run it in N long enough to see if you hear a rattle

if there is no rattle when the muffler is off...replace that...if there is a rattle with no cat and just the y pipe...get a resonator

 

the thing with my exhaust is..its all 1 piece after the y pipe..ill unbolt it after the y pipe and see what happens...hopefully i dont hear anything

 

arrite dudez..i unbolted the flanges after the y pipe n started it up n gave it some gas n happy to say...it didnt sound like how my exhaust sounds in my video at all!! so in my conclusion..i need to change my muffler..that piece of $hi... Oh and when i started it up with the rest of the piping unbolted..it sounded like a monster! lol..
anywayz..thanks for the help everyone..

 

sorry nishan...I was talking abotu your video...I was thinking you was the op. Wonder what happened with nopike.

Anyway..from the video...it sounded like your muffler. Its actually kinda easy to tell..when the motor sucks back a bit you immediately hear some baffling slapping around. If you really want to make sure...when its still cold, have somebody start the car and rev it to make the sound and put your hand on it and see if you can feel it bang around in there. Should be pretty noticeable.

peace and good luck.

 

yeah its loud as hell without a muffler lol...i had a hunch it was muffler but that was the easiest way to check

 

this is probably not what your problem is....sounds like a metal against metal vibration of some sort, maybe an exhaust leak...u sure they mounted ur b pipe correctly?


edit..sorry just saw that it was your muffler...interesting..

 

Johnny black, the reason y everyone keeps bringing up hondas is cuz the most commonly heard car riding down the road with that sound is usually a civic, i owned one and my friend that i bought it off of had a muffler that sounded like that. it's the engines in the hondas that make the sound. yes other cars do have that but the hondas usually have that cuz people put cheaper parts on them to "rice" them out. i also had an integra, but hat had a very deep sound to it, i didn't put a crapy exhaust system on it.

My exhaust system has like droning / vibration noise. I notice it most at about 40mph at 1500 rpm. It has to be the Y-Pipe or the Cat but everything appears solid with no leaks. I put new hangers at he y-pipe to support it better but that does not help. It appears that the noise is from the way the exhaust travels through those pipes? Not sure what to do, I may look at putting a stock y-pipe back on.

Thing is the system ran just fine for the last two years until a couple of months ago. I did not do anything to it at that time.

Thanks for asking!

 

yes..I realize that, and I also realize that when this happens it demeans the manufacture and the enthusiasts that have good cars. Also if I may point out it has nothing to do with the engines that are in hondas specifically like you say, cause it can actually come from almost any motor that is N/A and doesnt have a properly constructed or possibly cheaply designed exhaust system. I have had hondas for over ten years...and nissans as well, and well a plethera of other vehicles as well that arnt worth mentioning, but the biggest difference here is that hondas rev higher to be fast..usually, and nissan make better torque and dont require to be reved to be fast. So when some idiot driving a honda with a cheap exhaust system rolls down the road at 7-8 thousand rpm....your going to hear it. It makes it quite a bit more noticeable...but..a nissan, dodge, ford, subraru, with the same bees in the can sound does it can only rev to say 6 thousand rpm...well..you cant hear him for miles like the high reving honda.

hope you get my point. My crx BTW was a 12 second car, had almost every thing done to it that you can imagine...but I made sure it could be driven daily, it handled great...but still soft enough for comfort, the exhaust consisted of 3 inch pipe from the turbo to a cat then a cherry bomb..and then exit off right in front of the right rear tire. It sounded amazing....and I had people wonder all the time why something that was so fast, and consisted of such a simple exhaust system sounded so quiet. Research, and trail and error people.

Still..it would be nice if this bees in the can thing would not be just a honda thing at a nissan website....cause it is not just a honda thing.


nopike...yes..figuring yours out is a little more difficult cause its at speed that your getting your issue. If I can ask...do you have a resonator on there at all? if you do...try this...when its cold..try hitting it with your hand..a couple of good thumps and see if you hear in glass in there moving around. I rarely see cat failures...usually at the track when some fool puts C16 fuel in there car for that extra bit of kick...haha..yes I did this..it was a spectacular fireball when my catalyst came out the rear of my car.

Its about all I got buddy....good luck with it.

Thanks, but it has a new mufler and b-pipe that did not make any difference. I notice it on start-up also and at certain speeds/rpms. I tried tapping everythong with a rubber mallet , all solid no unusual sounds like something loose, broke or rattling.

 

or is it warpspeed's Y-Pipe??

 

I'm really suspecting that but it sounded just fine for almost two years with this same set-up. The only thing that should wear on this pipe is the flex section but I just don't see any degradation.

 

sometimes inside the flex section over time the material can break down a little..and the metal might hit agaist eachother causing a rattleing kinda noise when the pressure hits it....

 

+1 flex sections of all y pipes dont last too long

 

I think you are correct, either have to get new flex section or Y-pipe. I will make sure it's a lined flex section like the OEM one.

 

i say you get the whole y pipe, i got a flex section repaird before and the weld wouldnt stay... every week i had to take it back to the shop to get re-welded... swap out the y pipe ftw..
