I just installed a new Warpspeed Y-Pipe. Now on acceleration I feel a harsh vibration coming from the exhaust where the Y-Pipe is. There is no noise at all while parked in the driveway.....all the way to redline. On the highway, the vibrations can only be felt during acceleration, and not at a constant speed. Around town at lower speeds is where the vibrations are most intense, and it seems as if there is something rumbling and vibrating until you let off the gas.

I have attached a video here that is compiled from several sound clips taken with my cell phone today. Turn up your speakers a little, and you can definately hear the rumbling and vibrations that I am referring to. The clips don't nearly do the vibrations justice, as they feel and sound much more intense when you are actually in the car. My phone has a crappy mic I guess, but the video definately gets the point across.

I'm sure that someone has run into this problem before, What exactly is doing this, and what do I have to do to fix it? Any help is greatly appreciated....

Here is the video.....

 

weell i recently bought (iirc) a warpspeed ypipe for my 4th gen from a local seller.
i also noticed the rumbling/rattling. the link below talks about the rattling i experienced while launching/accelerating from a stop. But it has been about 3 months since i had the ypipe and the rattling has dramatically decreased from what it was before.

Thanks, I found something there that definately soinds like my problem:

Under the 95-99 Maxima:
"Some have complained of the pipe hitting the cross member under the car when launching hard, which makes a rattling noise."

How would I fix this? I guess that I would have to get a bushing to go up there, then hold it in place.....That would be a big pain, and would probably still rattle. I wonder if WARPSPEED would do anything to help....Probably not???

 

Had the same problem, it was the pipe behind the cat hittin the cross member. I did two things to get rid of the problem:

1 - I reshaped the hanger to pull it up a bit higher
2 - used a hyd. jack with a block of wood - placed under the the pipe and jacked it up to try and bend it up.

It has helped-the rubbing has gone.

 

Thats why you shouldn't have cheaped out and bought the warpspeed. Should have spent the money right the first time and bought a cattman.

 

The cattman would have still provided a generic bracket that would have needed to have been replaced (Or so I am told by a guy on the Nico Forum that's been installing them since the beginning of time for Max Y-Pipes ~ '98)

I actaully did the same thing to fix the problem. The supplied bracket was pushing everything back & down, which was causing it to vibrate on the cross-members due to flex on acceleration. Now everything is fine......

 

Thanks for the constructive reply. Some of us do have to work around a budget and for the $100 I saved bending a hanger and a quick jack was no big deal. But again thanks for your knowledge and wisdom, it is what I am coming to expect from the "senior" members of this forum.

 

I wasn't trying to sound like an a'ss as it was my opinion. Plus I would never give a penny to WS as they are a shady a'ss company. They are pretty much hated (not hated but I don't have another word for it) by quite a few members on this forum. If you don't want smarta'ss answer then don't ask questions that have been beaten to death. Thats why there is a search button.

 

I have never heard of that prob from people that I know with the cattman headers.

 

I have purchased and installed both a warpspeed and multiple Cattman Y-pipes. Both of the warpspeeds I installed had fitment and rubbing issues the required modification to fix. I have NEVER had a problem with a Cattman product fitting exactly as advertised.

Sure you might save some money, but you also get what you pay for.

 

dont listen to what half of these people are saying. they quickly blame the brand. i have had a WSP y for 3 years no problems. there is a metal bracket right near the cat convertor, you need to take that off and then the vibration goes away.

 

 

I helped organize one of the first Warpspeed group buys back before you could even drive. QFT .

Are you referring to the cross member?

Since when do you have a 5th gen? Hmm, I guess I have a 4th gen so I can comment too.

I had a Stillen 1st gen Y, and it never gave me any issues over 3 years/~70k. I had a WSP for the same amount of time and it bangs on shifts and vibrates under acceleration. But I paid 160 USD brand new for it, whereas I paid 250USD used for the Stillen.

Stillen also sounded much better. Again, this was on an A32.

 

lol I just noticed this but I guess he bolded the letters to try and distract people from reading our comments.

 

Apparently he needs bold letters for recognition because otherwise, people would rather not read his posts.

 

I concur

 

The Law-thanks for your explanation, it just came across very sarcastic.

But I do find it a bit funny that when I did search and posted a tread asking about the any problems with either pipe how one had much to offer, think I had 9 replies to my thread. Now when someone has a legit issue/question so many people are out to "own" them, rather than be helpful. Is that not what this forum is about?

 

No one owned the OP. We have had related issues, so we're relating common issues, another item this forum is good for.

 

Well if it was a legit issue/question that hasn't been beaten to death then people are willing to help. But if people ask about stupid questons like intake threads or "how can I get my car to sound like a g35" thread then it gets old. Plus nobody ever searchs which makes things like 10 times worst since more than likely the thread could be found in less than 10 seconds after the search.

 

I can understand, a lot of the threads are duplicate and some are down right stupid. Like I mentioned, when I searched I did not come up with any issues regarding the rubbing (though that was before I became a donating member).

Maybe it is just me, since I had the same problem, that I felt it was legit.

That's my 2 cents worth, have a good evening guys.

 

what does that have to do with anything. did i target any of your posts?

 

Yes, you said most people on here don't know what there talking about, and not to listen to them. You even put it in bold. You called out everyone who had posted before you with that comment. I've been dealing with there product since it came out, and have been turning wrenches for the better part of the last 12 years, but please, feel free not to listen to anything I have to say, I'm just interested in spending too much money for stuff, it's that cool money tree I have growing in my back yard you see, they grow great with all the rain we get here in Seattle.

 

exactly........

here an example of the type of person i am talking about....


completly irrelevant to the issue. yet he is quick to throw in a smily




in my 6+ years of browsing the org, i have never quoted any of the mods/admins as uninformative people.
