first dyno soon need advice
 

my brother/superdooty and I are hitting the dyno in a week and were talking smak, i was wondering if id be worth the $60 for a muffler delete pipe and possible a cat delete pipe $130, maybe the egr plate, boost fooler,ect? any ideas welcome. I already have a AFE intake, 4inch exaughst system, edge attitude (wifes buying me the unlock code) meth injection, newer injectors. thanks in advance

if you already have a 4" exhaust you wont gain much by putting in a delete pipe

do you actually have a Catalytic converter on your 01? thought that was a california only option

ya the 1st owner replaced the system with an aftermarket one but it came with a cat and muffler, it is origanly from cali and im the second owner
