The exhaust is made with Aluminized steel and shouldn't rust. The only problem I had with the exhaust is where one of the hanger brackets rusted off. I just welded it and it is fine. The only issue is the whistling.Mine makes some noise. I want to replace everything from the CAT back though. Car came from up north, so the exhaust isn't in the best shape.
Yeah? Tell that to the holes rusted through the flanges. It’s not falling apart. But it will need to be replaced at some point.The exhaust is made with Aluminized steel and shouldn't rust.

It could be the actual drive belt. Try spraying water onto the inside of the belt while you're hearing the whistling. If the noise goes away you've found your problem. Let us know.This happened after I swapped belt, air filter before a long road trip in 2015.
Recently swapped air filter, belt and belt tensioner hoping it would eliminate the problem. No joy.
Also had some exhaust rattles which were fixed by just using a stainless clamp to put the parts back. Perfect fix, no welding needed. (not the right way but learned that trick on an old Jetta exhaust).
Just heard another 05 or 06 CR-V passing, screaming under acceleration: Same noise.
If it's just something in the exhaust I guess we can live with it. Looked for a vacuum leak but couldn't find one.
Hi I’m having the same issue. Same model and everything. Have you resolved your problem?hi I was wondering I just brought a 05 cr v se and when the rpm round 3-4k it makes a whistle sound, it stopped when I let go of the gas pedal. I asked my friend he say its like that, and its say because of the oem cone shaped air filter that making the noise. I don't really know why would a cone air filter make a whistle sound when it hit 3-4k. any1 have this problem before and know a fix for it or if there something wrong with the engine or something.
I am going to replace the muffler with a honda factory one and see if the whistle goes away. I am also going to dissect the old muffler and see if it has restricted the flow.Yeah?
