Hey everybody,

I posted here a couple months back when I first had my Budget (LSS) Y-pipe installed. After installation, my Y-pipe would give off a hissing air sound under WOT, at any RPM. It sounds almost like crickets chirping. I thought it might go away as things settled into place, but the sound is as bad as ever.

I checked under the car and everything looks tight. The only thing that concerns me is the mechanic hammered the rubber gaskes into the new y-pipe while it was off the car, then installed it under the car.

Has anyone else experienced this before? Think it's a bad ypipe or a bad install, or just normal?

 

i think u just need a set of gaskets. there are 2 total metal crush ring gasket attaching to the exhaust manifold and the gasket on attaching the ypipe and the cat, not sure if thats rubber, might be a metal one..i dont remember.

so when its on idle, it still makes that hissing sound still?

 

My Stillen Y-Pipe makes that hissing noise at WOT. My gaskets seem alright. It has made the sound since I installed it, 1 year ago.

 

it is probely the exhust ecaping form one of the gaskets or it is a hole in your flex section, check those out as well

 

The hissing only occurs at WOT, so daily driving or idle doesn't sound bad at all. Accelerating through a tunnel though is embarassing, it sounds like an army of invading crickets.

Anyway, I'd like to replcae the gaskets but the ypipe only came with the two needed. Does anyone know the specific size / material of the gaskets, or of any replacement parts?

 

I'd love to hear this.

 

A friend of mine has a Cattman and has this sound. It would make sense if it is the gaskets because his was bought used.

I know that sound though, it is pretty crazy.

 

I used headerwrap on mine and the hissing diminished greatly. I've had it on there for a while now. I also live in Southern California where the weather is not really an issue...

 

Yup, you ever try the drive-through at McDonald's or a bank?

 

I remember that.....

 

My budget SS y pipe makes that exact noise. Mines been on for about 5 months and has made the sound since day 1. I always compared the sound to a rattlesnakes tail but a horde of crickets might actually be a better description. It doesn't do it at idle or when I'm really easy on the gas. Press too hard and it gets pretty loud. I'm wondering whats causing this too. It came with the 3 new gaskets that are needed and I had a muffler shop put it on. Everything looks right under there. I was starting to lean towards putting header wrap on it too.

 

I would say to take the wrap off during the winter.

 

lmfao @ all of you, I almost died reading this thread (still laughing like an idiot). "An army of invading crickets" hahahahaha.

 

Atleast you don't have bees in a can from a STOCK one

 

Before I wrapped it I thought about going back to the stock one...

 

im getting my wrap put on 2m...did it really help or should i not bother?

 

It's prolly a leak in the pipe, call budget back and ask them to ship you another and ship back the old one.

 

I had a click-click-click in my Budget Y when I first put it in, I called it the 'VW Karman Ghia Sound'. Turned out to be a bad weld on the inside of the Y, not vivible on first inspection but visible after 200-300 miles of driving. Called Budget, asked to have a new pipe tested and cross-shipped, installed and all is quiet now.

 

Same problem here. It really does sound like a rattlesnake...

 

For those who tried the headerwrap, did you wrap the whole thing or just the flex section?

Sending back the pipe to budget would be a hassle, especially since I don't have gaskets for my old y-pipe. Does anyone know the specs for the gaskets used, or where you can get replacements?

 

If I wrap the flex section in header wrap, will that affect its ability to flex when the engine torques back? I'm in the same boat as the other guy.....taking this off and sending it back to budget would me a major hassle. I didn't install it myself so I would have to pay to get it taken off and have the old one put back in. I would need to get some extensions for my socket set plus some other stuff to do it myself like gaskets, o2 sensor sockets ect.

 

If you guys have a leak, that needs to be fixed.

If you want to reduce the noise that is associated witht the pipe itself, the headerwrap works. I wrapped it from right under the front O2 sensors all the way back to the catalytic converter. I tried just doing the flex section, and was not happy with the results. Wrapping the whole thing did the trick. It really helped reduce the noise from the pipe.

 

Advanced auto parts has the correct gaskets for the ypipe. I just don't remember the part #.

And yes I have a slight hiss noise from my Budget pipe as well since day one. Now I have a hole in the flex section due to my car was so low. Will be getting wrap for it soon to cover the flex section up.

 

Im planning on buying a budget y-pipe soon, and I want to be able to aviod this hissing sound that seems to have evolved itself from the ominous "bees-in-a-can" noise threads a year or so back....
So everyone is using gaskets to fix the problem or what? If its the flex joint shouldn't you be able to exchange it? From what ive read; header wrap only deafens the sound....it doesn't completly fix the issue..

 

The hissing is nothing like "Bees in a can".

I have a question for you guys with hissing Y-pipes. Does your's make any other noises? When I rev to about 4k in Park I hear like a metallic rattleing. I was wondering if it could be related?

 

I did get the metallic rattling sound -- usually at slow speeds under mild acceleration. Turns out it was the heat shield rattling below the Cat. I used some high-temp oven tape and taped everything where the heat shield might touch the cat.

That fixed it no prob.

As for the hissing, I think headerwrap will be the solution, unless you have a leak.
