3" ultra flow stainless on atr ???

[Mike70gtx]

I've got the atr 3" dual system. was going to use my ultra flo welded on them. But mine are offset and won't work. Is anyone using the round stainless ultra flo? (only one in 3") If so would I get the 12" or the 16" to replace the pit bull? Will it sound like the welded? They have a $75 rebate on the stainless and $50 on the welded at Jegs.
