I've been noticing this jingling sound that is similar to loose bolts after I installed my test pipe the other day... The sound is only noticeable at really low speeds and you have to listen for it to hear it; but now that I know it's there it really annoys me (mostly because I'm worried it's causing some kind of problem).

I originally installed the testpipe with 2 bolts that were not fully threaded so I thought that was the problem. I took them off and put fully threaded bolts and tightened the other end down with some nuts, have some spring type washers in between them too.

Does anyone know what is causing this sound? Nothing seems to be loose when I'm down there, and I tightened everything...


and it's really quiet so I can't record it for anyone to hear... just wanna know if anyone has experienced the same problem or knows how to fix it/what it is

Do you still have the heat shield on there? Could be rattling

most likely the heat shield. I had a similar problem before

isnt the heat shield on the cat? i took the cat off...

theres another shield above that. Just bend it up a little so it cant touch the test pipe if its vibrating

after about an hour of trying to get that stupid ****ing heat shield off I finally got it off (had to undo like 6-7 different bolts that were connecting it to that steering column thing)... got the damn heat shield off... put the test pipe back on

AND THE JINGLING/RATTLING IS STILL THERE!!!!

leaving the heat shield off, hope the evo doesnt mind


does anybody have ANY IDEA why the car is making that noise? or should i just accept the fact that the evo is a NOISY CAR

did you use gaskets when installing the test pipe?
does it look like the o2 is hitting anything?

I did use gaskets for the testpipe

Doesn't look like the rear o2 sensor is hitting anything

so far the possibilities I have are :

the o2 bung plug I put into the test pipe (got an M18X1.5 oil drain plug and used a ratchet to tighten it)

could be that the whole exhaust system is somewhat loose (hanger problem?)

downpipe hitting the 2 crossbars is the most logical thing... they seem pretty close


solutions : heatwrap?
remove crossbars?

we all know how noisy the Evo is, I just got used to it from day 1.

I just fixed this on my IX. Have a stainless 3" downpipe that was hitting the front sway bar.

It was so close, that it was pressing against the bar all the time. I couldn't even slide a piece of paper between it, it was so hard.

So I used a floorjack and jacked up the downpipe, that was enough force to lift it off the swaybar. I folded up a piece of fiberglass exhaust wrap so it was a thick cushion, and wedged that between the pipe and swaybar.

Then I used two stainless high temp locking ties to secure the fiberglass.

False knock issue gone, car pulls much harder, and no more loud rattle at certain speeds.

I had the low speed jingling noise just like you describe. I couldn't figure it out either. I also had a buzz/rattle in the dash by the driver's A pillar. i went to work on the dash and got the buzz gone. This killed the jingle noise too.
