like i was saying bro, the only header that i would stick on my car is the gmpp header cuz i know that one fits with out a doubt, and the CTI header. I regard the CTI header as a true upgrade. Im not trying to say that the other headers are inferior or anything, its just personal tastes.
that 4-2-1 setup looks pretty siq though, and i have been waiting for sombody to come out with one for us
only problem with 3" on an na motor.... your going to lose all bottom end power for minimal top end gains... and the c/a one I have is enough to keep some low end and now with the 3" d.p. and 2.5 catback, car def hauls through all ranges of rpm's
This is exactly what i was thinking since im N/A I probably dont need a 3" exhaust........ BUT the Vibrant header shouldnt be too bad, ya think?
Id have the vibrant header/DP combo going into my 2.5" Thermal exhaust.... i shouldnt loose much backpresssure eh?

Should be fine... as long as you have an intake or something to balance off the air intake and air going out of the motor... you should see some nice gains
