Thats good to hear. I just realized that you are 2ZZ.
The Magnaflow downpipe although a replacement for the stock is too small of a diameter and probably restrictive to keep it 49 state emission compliant to get the most form the 2ZZ. It will actually be more restrictive than a stock exhaust system made for a 2ZZ application.
There is a good amount of horsepower left off the table and if I would have known I would have recommended going with the PPE downpipe or the Che with a modification to get it to fit like mine.
I have a 1ZZ motor.
Sorry About that. I mistakenly thought that because you bought a 2zz pulley and now I figured out you adopted a 2zz water pump to fit a 1ZZ engine.
I suppose you are good to go with the Magnaflow downpipe.
Good to hear. Generally on other cars the cooling will come into question when the cooling capacity is saturated. Fortunately the pump was designed for a front engine car with less coolant capacity where we have more so it’s possible you will not see the effects of coolant overheating issues on the street.
