yes those are the reverse flow glass packs, I have those. There are reports of people blowing out U joints after swapping something better flowing on Like sts baffles

Hello,

I just saw a photo of side pipe mufflers you posted.
I have the same mufflers in my hooker side pipes and are trying to identify what kind they are.
You say these are reverse flow glaspacked ones so that means they are the most restricted ones right ?
I took them out but can't see any glass around them but the inside looks like yours


Thanks for your help
