Thread: Does a resonator could choke the exhaust?

Here is the thing, I got a VE'd B14 and I'm running a 2.5" mandrel bent exhaust using 2 Magnaflow 4" resonators so almost thel whole straight line is occupied by this bad boys, also I have a muffler

My exhaust system is pretty quiet and absolutely love it because of that but, besides the extra pounds of the second resonator do you think that would steal me some power?

In theory there must be no power loss but who knows.

Is really that quiet that you could not tell easily when cams kick in but they both do

The magnaflow resonator's a perforated core, so very little flow is being hindered, now if you were using louvered core resonators, then they would disrupt flow a lot more and rob you of power.
