the search didn't work for me either so i'll ask my question here....what is the best exhaust to run with a t rex? right now i have it dumped right after the headers with 3" dynomax bullets..just like the sig says. some people tell me to run full exhaust or at last an x pipe to gain some back pressure...others, including thunder racing say that back pressure is a myth and to run what i have if not open headers.

they said the sluggishness down low is probably due to the 4.10s with that radical of a cam and to bump to 4.30s..which are getting put on thursday
