Hello!

As the topic says, my box makes a strange noise when accelerating from 0-25mph.

It sounds like an old Volkswagon bus engine.

Im sure it is just a part but I dont know much about under the hood.

any insight would be great!

Thanks,

I see you added an exhaust to your car , take a look at the gasket/donut , does it happen to be bad?

 

a vw sound would promt me to think a bad exhaust manifold to down pipe gasket.

 

Sounds like the rear gasket has gone bad. I had to replace mine when I added the Strup axleback. They are like 10 bucks or so at the dealer.

 

Wow, thanks for the quick responses. Where is the gasket??
I appreciate the help!
I will def look into the exhaust.

Thanks guys!

 

It's located between the rear section and the rest of the exhaust. After several exhaust changes mine just fell apart. You only need to remove the clamp. Pull the pipes apart. Slip on the new gasket and reassemble. When the gasket is bad it will leak and allow the muffler assembly to move around and sometimes get too close to the bumper opening and melt the hole. Center the tip in the opening before final tightening of the clamp.
No problem on the quick response That is why we are here. To help fellow Scion Nuts.

 

easiest way is to open your hood, start the car and listen for the noise ( getting a buddy to help is great).

one gasket is between the head and header ( exhaust manifold), second is where the header connects to the pipe w/cat converter,resonator, the third ( which is one that maybe the problem ) is just over the rear axel ( when you added the new exhaust this is the most likely one to get damaged )

hope this helps

 

thanks! I will check it out this week and get back to the post!

There are worse things than sounding like a Vdub........LOL

 

Yes, but not when driving an xB!

 

I brought the car in a few months ago. They replaced a "doughnut" in the exhaust. So far it has sounded better than what it was. Thanks for the advice everyone!
