Hi guys,
I have what may sound like an odd question: if you put your hand at the exhaust pipe, and you have dual pipes, should the pressure coming out feel the same on both sides? I am going to do a leakdown test to verify, but I find it someone weird that one side seems to push the exhaust out harder than the other side.
Any thoughts? Is that normal at idle?
