Hey guys, this is probably a stupid question, but I'm not sure of the answer.

How do I take the baffle out of my Akrapovic exhaust? There is a rattling noise coming from the exhaust and the Honda dealer said that the baffle is the culprit.

Thanks in advance!

Should be a screw underneath the exhaust outlet you need to remove.

Then you pull it out as evenly with everything you can find that can grip the inner baffle without destroying it. It’ll come, you gotta want it.

Once it’s out once it goes in and out much easier.

I just did some googling. There is a spot weld on the side of the bolt. Gonna have to figure a way to get it off.

Can you post a pic? I’ve not seen that before and I’m surprised they’d do that unless it’s a Euro 4 or other emissions/noise thing.

I’d have to pull it off again. I’ll try and do in next few days.

It’s slightly off to the side of it you can see a partial hole that they’ve put a spot weld to the screw. I’ve read you can get a tiny ass file and just file it apart.

Wish I knew before Hand cause I basically stripped the bolt already trying to get it out before I noticed it.

there was a spot weld on my bolt, I just broke it by giving it a tap with a mallet while twisting it loose. Job done! That is the easy part.

Getting the baffle out is a pure struggle, I gave it to Honda at the end and they came back saying "never again!", but they got it out.

Once out sand the collar down a little at a time till it sits well and get outs without much effort. then put the bolt back if you want the baffle back.

Some say use a lot of WD40 or similar products to loosen up the collar.

Best way is to get something through one of the ports on the baffle like a spring hook tool or something and then start pulling it, usually a mallet and tapping it may help.

These are some ideas. Let us know how you get along.
