Some people may argue differently, but a 4in exhaust is a 4in exhaust The sound isn't going to be much different from each other when comparing straight to straight basically.

But yes, MBRP is a good quality exhaust from my experience. I've installed a couple sets myself and they're not bad.

I've got a set of Diamond Eye 4in duals on my LB7 and I won't lie-good exhaust, royal pain to install...

My last two exhausts I have put on my own trucks have been MagnaFlow 5in. By far the easiest installing and best fitting out of the box I have ever installed.
