Restrictions from mufflers

jcain · Jun 13, 2019

My truck had a slight hum/drone at 2800rpm for about 20 rpm. Full 5inch exhaust no muffler/resonator.

Just sayin

I guess we'll see what the new set-up does. I bet it has absolutely zero drone

I can tell you this though, with the last setup, the gutted *** and factory resonator was a HUGE restriction. I took it off after growing some nuts, went to the Rudy 5inch straight, and my God the truck woke up. Quicker spool, cooler egts and a ton more power everywhere.

I have some real world data- i think my truck is super sensitive but i put on a flo pro muffler and a aero turbine resonator- the truck lost its spunk in it no doubt and cruising egt temps were 100-200 degrees higher.. illl deal with the noise, straight pipe back on and truck is not back to its snappy self.
