Yet another Cheap exhaust mod
Hi guys,i came across a very simple yet glorious sounding exhaust mod while playing around with my car,i cut 4 square openings(about 10cm by 10cm)on all four rear cans and removed the silencer material,then i closed the openings with some mesh wire,the resulting sound is toxic,at startup and idle its very deep and bubbly but as you pick the revs it changes to a high pitched wail.I have headers,decats,oem h-pipe and oem resonator,Picture is shown below.For those of you who have spare oem cans lying around you better try this!
What i want to know is that does this have any negative impact on the Engine,Power and fuel economy?
