Exhaust question ?

[blacktruck]

I have a 2005 tahoe with the one in two out muffler.I replaced it with a flowmaster super 44 one in and one out.Are there any disadvantages to doing it like this?

Not really. is it 2.5" or 3" inlet? single 3" out? or 2.5" outlet?
a lot of people chose to go single in and out. it will still flow better that the OEM.
