Default What is this part?

Can someone identify this part and tell me if it does anything or if it can be removed? I’m putting in IPD Y-Pipe and Plenum and I’m not sure what it does! Thanks for the help as always

Looks like the Sound Symposer.

You could plug the ports and remove it. Less noise transfer into the cabin.

Yes it's real and yes I have deleted it.

Get a heavy duty cap that fits the bung on the y-pipe and secure it with a strong clamp, not the simple spring clamp that holds on the symposer. Add a small piece of duct tape to cover the hole that goes into the cabin.

Cleans up things nicely.

awesome, thank you for the heads up. I guess I need to find a rubber cap strong enough to hold the boost

My buddy had some he purchased, I think on Amazon, I'll see if I can get a link to it. I think they were heavy duty silicone reinforced caps...

With just the spring clamp, I detected air leaks. A stronger worm drive clamp and all is tight.

Here's a couple of pictures from when I was pressure testing everything (soapy water spray everywhere). You can see the capped off port that normally goes to the symposer on the left side of the y-pipe. Some y-pipes don't even have these ports, and I guess some have welded a cap over it, but my flexible cap solution has worked great so far.

Home depot rubber chair leg caps and clamps. Either 3/4" or 1" I forgot what it was exactly.

so I just mic’s it and it measures 33.4mm at the tune end and there is a tapered lip that is about 37mm so a 32mm is the ticket! Also the inside of the rubber tube that was on the original Y-pipe is 33mm ID so 32 should work perfect.
