Have you seen these termi's before?

[duke8]

Hi everyone

I have scoured the web and cannot find any info on what I'm looking for, so I thought I'd ask the knowledgable folks that frequent this site.

I have just got some low mount cf termi's which originally came from an s4. I bought these knowing that they had what the previous owned referred to as non removable baffles.

Anyhow I decided to shorten the cans and whilst at I'd remove the baffles. When I opened them up I was surprised by what I found.




From what ive heard, although can't confirm, other termi's are straight through with a removable baffle however mine have 3 separate compartments (you can see where rivets hold two of the plates) with pipes linking the top and bottom, all within the perforated oval frame.

my questions are

1. Are my pipes some sort of euro spec pipes or EPA type approved? ( previous owner Believed this was the case) they have an "e" number on the end cap

2. How are normal oval  termi's constructed? Ie is the perforated oval frame the actual pipe or is there a smaller pipe that runs through the centre of the frame, or is there usually no frame? I haven't seen any oval termi's disassembled, so I'm not sure.

If anyone has any info or pics, it would be most appreciated.

Thanks guys
