Default what us the best exahust system for a LB7

Hello everyone, I've googled and done general searches on this subject and just figured I'd ask yall. Is a bigger exhaust worth it or could I just straight pipe the factory one?

MBRP 4" turbo back will do you right!

does that mean a straight pipe system or muffler?

What the quality or difference in using a Flo Pro system vs MBRP

I found these:

Flo Pro:
Flo Pro 801 4" Aluminized Turbo Back Exhaust With Muffler
Flo Pro 801NM 4" Aluminized Turbo Back Exhaust w/o Muffler

MBRP:
MBRP S6004P 4" Aluminized Turbo Back Exhaust With Muffler
MBRP S6004PLM 4" Aluminized turbo back Exhaust w/o Muffler

From what i've read, i believe MBRP makes flo pro.

As for the sound. If you like it louder, no muffler. If you don't, get the muff.

I run no muffler, but i have a CCLB and can't even hear it in the cab. But it's sure loud outside when i romp on it.

Nothing wrong those and a damn good price too.

Pipe is pipe. Don't let anyone tell you different.
