Hi fellow TOCAU members,
I have been doing some research on headers availible for our 2ZZGE corollas, thought I would just post up what I have found including pictures for anyone that is interested.
TRD: Similar to the stock headers, just with longer primary pipes. Gains expected in top end power
CONE: Im not to sure about these. Im looking at rollamods for answers in regards to these headers, I think they are a 4-1 design from the picture.
CES: These items are just the stock headers ported and polished with HPC coat. Gains expected in low to mid range power
Just a quick question to those with the TRD headers, is that little square hole in the headers for air injection?? I cannot see one in the C-one headers.
If someone has a picture of the CES headers please post them up so I can add it. I cannot find the old CES thread with the pictures.
