tsudo 4-2-1 header
so i finally installed my tsudo header onto my 2.2 ecotec.
my first thoughts were, didn't do much, but my o2 sensor wasn't plugged in.
but now i've been driving on if for about 2 weeks, no leaks from the header yet (fingers crossed for a long time) and i can say i'm glad i installed it.
installation wasn't very hard. getting it in without taking the valve cover off is a pain, but possible.
and the performance, i can feel it pull a little more low to mid rpms, but not a whole lot different. i believe this is because i have it crudely attatched to stock exhaust.
and i do believe this has helped gas mileage. i'm going to keep tabs on it, but from what i can see from this 500+km trip i took today, it did infact help
so my final opinion. glad i bought it, but be sure to install it properly so you dont have exhaust leaks
