Unless I'm mistaken... You're offering two styles of muffler, both Magnaflow...
Option #1 XL Turbo, 3-chamber, SS, no packing:

Option #2 Straight through, Satin finish SS, w/packing:

Option #3 Straight through, Polished finish, w/ packing:Same as #2 only polished.
Is this correct?
Also please confirm: The "Magnaflow sound bite" is the straight through design, NOT the XL Turbo design?
I used to have the straight through design on my single out system and it rasped some around the opening of the secondaries, about 3 months ago I switched to the XL Turbo... No Mo Rasp!
I'm just saying...
