exhaust is supposed to give you the best performance for the celica, but isnt the Kazuma "THE" TRD
exhaust or is it just another type made by TRD
Assuming the first question is yes, i want good performance but i dont want it loud, which exhaust?
Last question is about headers, when you buy headers do you still connected the bottom header pipe to the Cat converter? or does it go straight to your CAT back system?
