I was wondering, after the downpipe, what are the exhaust sizes you guys are running? currently im having 2.5" downpipe with 2" all the way back to muffler. wondering should i upgrade it

Hm... based on his spec, he is using 2.5". Does it affect alot on his low end? I do have impression that the low end is going to suffer alot

i have a turbo auto 7afe and if you are running a turbo i would not run any thing less than 2.5" as your turbo wont be able to spool right , it is like trying to push air through a straw the bigger the straw the easier it is , as far as the loss down low your turbo will make up for that as it will give you boost sooner
the smaller pipe will give your turbo a little more back pressure than what it would want
