Mine are the universal Magnaflow cans that you get at a local muffler shop (straight through design). I think they are PN: 11226. I didn't add them until after I put on the headers... so I can't compare them to stock. I can tell you that out of the 4-5 setups that I have had, the best sound with the least amount of drone was LT headers and stock mufflers. I blew out a baffle in the stock mufflers and it was rattling, so I had to get the Magnaflows.

Hi, what mufflers did you use where QTP are mounted ? axle back ? sound
level equal to stock? any drone? Thanks Bobby
