Twin exhaust but only one side really blowing
Discussion
lads you mite shed some light on this for me... i just noticed the other day with the cold weather, when i started the car from cold most of the exhaust fumes are coming out of the right hand side and very little pressure from the left... car is going great and engine sounds spot on ... is this something serious or normal ??? ( cats romoved from full system with headers )
I've had this before on other cars.
It depends if there's any shared part of the exhaust at any point or if the left bank of cylinders is compeltely separate from the right side.
If theres a common bit (say an exhasut box) used by both exhasut pipes then the gas will alway take the path least resistance so will in general appear to only come out one side. This usually happens at very low engine loads and once the engine is up to speed both sides are used.
However, if the two exhasut pipes don't share any common components then you'd expect both sides to have pretty equal emmissions.
