Re: Exhaust cutout/Exhaust Gas education please.
What you looking to find out? My cutout basically replaced the test pipe/cat.
Its awesome 4 seconds to open and close, DMH performance with 4 year warranty for less than $200 even with flowtech.
I love it. Plus all my car has now is rims and a FMIC to anyone that see it, not even exhaust.
