Hey im just wondering how much risistance is in the stock muffler. And also what size diametar is the stock muffler? Is it a good muffler for being stock? Im doin the custom axle back conversion and possibly droping the res to see how it sounds, if it sounds too ricy then im goin to upgrade the res. Opinions?

 

i heard it is pretty restrictive

 

the exhaust diameter... starts out as 2.5 OD and then changes to 2.25 ID
