First time hearing rain squeal and I have the EST Sport exhaust!

Driving through some heavy rain I heard the annoying rain squeal, sounded exactly like the painful sound in this video:


I have the EST Sport exhaust, so no resonator. Why would it still squeal?

Here's the exhaust install thread with pics, had the JRL mod done as soon as I got the R never heard this in the rain before!

Any idea what it could be?

You are going to have to inspect your drive shaft to see where it is being contacted and what is contacting it.

Yea that was the first thing on my mind. Even without a resonator I wonder where it would be contacting.

Here's the deal fellas
When I had my EST with a resonator on, I got rain-squeal once. The Drive-shaft rubbed on the edge of the resonator.
Now, after I swapped out the resonator for a straight pipe, I pushed the exhaust up too high and one of the exhaust bends rubbed on the area where the drive-shaft goes into the rear dif. (think of it as right under the rear-seats in the middle. There's a rusty-round coupler thingy there at the end, which sticks out, and that's what was rubbing.

I suggest you don't drive a lot with it because you will rub through the exhaust and will have a leak, which will require welding. So get under there ASAP, or simply just lower your exhaust. Get under the car and bend it down - you'll be fine.

an update on the dreaded squeal:

found that one of the exhaust clamps were way too close to the drive shaft. repositioned the exhaust clamp and bent the rear exhaust mount brackets for some added clearance.

When i installed my EST exhaust I used pricier band clamps.
That wat the clamps don't crush the piping and it allows the tubing to still be a slip fit.
Hope you found the source of your noise.

Glad you found the cause. Don't worry about the mark on the drive shaft, the mark on mine is way worse but it's been fine for over 90K miles since I "cured" my squeal.

I used the flat style clamps and the problem was fixed with my est system.
