Chambered Magnaflow catback and H-pipe?

Just checked Magnaflow's website. The standard catback which I have has chambered muffs. Magnapacks are straight through.

Anybody else out there running an h-pipe with the standard magnaflow catback?

A prochamber maybe?
 
ok just double checked and they have regular mufflers that are straight through and they have chambered mufflers also. I guess I have the straight through? Can anybody tell me what the heck I have. I always thought the magnapacks were the only straight throughs. Geez told you not the first time I was wrong

do you have a p/n? i thought they all were straight through. i can see through mine if i hold it at the right angle cause it's not installed yet.
 
They must have just started using the cheapo non-welded Magnaflow XL's in their catbacks because thats the only chambered mufflers they have. My Magnaflow catback has their welded stainless mufflers with straight-though cores.
