Mufflex 3.5 spintech dual vs. hooker catback

I vote for one of the Mufflex setups but with the single out turndown.
Gives a clean rear appearence and flows better over a dual out setup.
Of coarse I'm Biased because I have the 3.5" SOTL setup with the 30 series Flowmaster.
Well maybe not everything but it is one of the best flowing catbacks made for these cars, so if you have a good setup like Kooks 1 7/8 LT's with a 3" y-pipe that has a flowmaster 4" merge and the hooker it will defidently flow like a ****.
But like you im biased since I run a Hooker catback, I showed over 10 rwhp on the dyno vs my old slp dual/dual which is supposed to flow really well?
Anyways heres a little info on pipe sizes

when i got on the gas however, the tone was awesome and nice.
its a different thing with a full exhaust, any louder now and i will have to put cats on.
