fyi in the car world the term "header(s)" should not be used unless referring to multiple "headers" such as,
"I am selling my next batch of headers"
"I just ordered a pair of headers for my 71 mustang mach1(it is a v8 and has 2 exhaust manifolds aka header(s)"
The term headers is to imply we have more than one header.
So your in the market for a header for your 4 cylinder car, since we have only one header.
Make sure you get it right because anyone with automotive knowledge will laugh at you if you say "headers."
right now on modded celicas(Intake
, exhaust, pfc) the Trial header, and the DC header seem to make about the same amount of power which is 1-2 peak hp.
Trial costs about 880 shipped in 5 days
DC costs about 260 shipped when the batches are made.
All our hopes are left with TPR, and that they design a good header that produces good gains on a modded celica.
