Any issues with a 2 in 2 out exhaust system?

[Brewcity]

Hey guys...sorry if this has been beaten to death, but couldnt find a real answer. I am looking into a 2 in to 2 out dual exhaust system for the 99 Tahoe...any known issues with this set up like back pressure or anything that would actually hurt performance over a single out?
I plan to run high flow cats as well.
Please let me know...just gt my Tahoe, and am new to the truck, so dont know much yet.
Thanks so much for the advice and help with this!

Nothing bad about it, only good... Kinda like H pipe, helps with scavenging and more flow then 1 out...

Thanks a lot guys for the help and advice!
I was just a little worried...I did read about it hurting performance from back pressure...glad to have your input. It really helps a newbie like myself!
Looks like I am going with a dual out! WOOOOO HOOOO!!!
Take care!
