Sound tube mod? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I kind of tried to see if this sound tube worked like the mustangs do. I pulled it apart starting at the big tube between the airbox and throttle body. There wasn't any sort of filter or screen there. Next, I moved to the apparent baffle that necks down to the small hose. I pulled it off, and there weren't any filters or screens. It seems that the only thing that does any muffling is that one canister. I now just need to find a piece of pipe that necks down and see if getting rid of that canister amplifies the sound.

Yay! First post.

I've revved up into the 6k range the other day.. I'm still being careful with my break-in, and I only did it because I needed to pass a car on a two-lane road and needed to be quick about it.

I was very dissapointed with the sounds I heard coming from the car.. Reminded me of a Dodge pickup truck... tons of sound with no corresponding acceleration.. .sound purely for the sake of sound.. and it was a bad sound.. all rumble and mess with no melody or tune.

I will definitely be removing the sound tube. what a stupid idea that was!

I would not recommend doing this. That canister is what separates the clean intake air from the "noise side" that goes to the firewall. If you remove it, you would effectively be creating a vacuum leak and allowing unfiltered air into the intake.

Just received our first batch of these.

There is very minimal cabin noise change but cleans up the engine bay.
