They are in the exhaust flow
It depends on what engine you have but the 02 is in the exhaust pipe or exhaust manifold and the EGR is a round disc shaped thing on the rear of the engine.

where is the mass air flow sensor located in the 2003 Honda civic
free flow exhaust with reducing bends
6.5 seconds, on a bad day....with a nice cold air intake and high flow exhaust.. 5.8
Check your exhaust. C converter for exhaust flow issues
no
as hot as the exhaust manifold there are exhaust gases passing through it
angle of the exhaust is to produce more power like the toyota supra almost all the exhaust are angled out so they get better flow which means more power the inlet is for different types of pipes like 2 inch inlet for a civic and 3 inch inlet recommended for turbo performance cars. inlets are to fit multiple different types of cars
