I have seen a few good deals with the SS manifold for IS300, and wonder if it will add pressure to the fuel consumption?
Many thanks in advance for helping.
Wow, reply from seller about this"the megan one is brand name version of the same header/downpipe. It come with 1 year manufactory warranty(directly from megan only). For the generic one, there is no warranty issue for that. This is the only difference. Both fit the same car and model."
Checked installation and everything correct, also the led indicator is on. Reset computer, and then engine light still came on after about 10km.............
Due to the engine light is on, gas consumption has increased about 20%.
