Invidia q300 mod
 

So my q300 has gotten louder. This is known as the packing breaks down. I recently did some custom exhaust mods with a local muffler guy on my 981 and I was thinking about opening up the q300 and repacking.

Any thoughts? Any one have a pic of what the inside might look like?

I love experimenting but I don’t want to destroy that exhaust either or ruin the sound.

I have also bought a few other exhausts and they were all too loud.

You may need to spearhead this. But if you don't want to destroy the exhaust you could either find a new muffler, or honestly, buy a whole new one.

Bought a new one and honestly it was louder. Maybe I’ll do some sound proofing instead. Let’s see if anyone else has any ideas. Thanks.

The reason I got rid of my Q300 way back was because the packing broke up after only a year or so. Switched to the HKS Legamax Sport and it sounded the same the entire time I had it. Same with the TRD Ver R muffler I have now.

Growing up as a motorcycle guy, I was always surprised car exhaust systems were not built to be serviceable. Repacking cans was a regular thing for me.

I have a guy who can cut it open for me and repack, but I have no idea what the inside looks like and don’t want to spend 2-300 without having an idea what to do. So I told him let me do some research.

No reason you can't mess around and try some different things, it's really up to you. I would say cut a panel out, make new panel slightly oversize. Repack with stainless and fiberglass packing. Seal back up with silicone and rivets. Have a beer or 3.

Thanks for the vid. I may give it a try or just live with a loud exhaust.
