I'm thinking about buying a flowmaster delta 40 to give my 2010 sxt that much needed aggressive growl. I've been hearing a lot of different info & need to know which way to go. @ amazon I was told that the delta flow 40 would fit but how would I run my needed 2nd pipe? Its a single in / single out. I was told by someone else that I would need a single in/dual out muffler but was then told that the muffler wouldn't fit. Can anyone here point me in the right direction?
