Need some help
So i have had my focus for 2 years now and i love it... i have been slowly modding it and i am at a cross road...
it is my daily driver and i do 20-25k miles a year... i had cai and race exhaust but it droned bad in the cabin and my girlfriend was ready to kill me... so i added a 30'' x6'' round muffler and everything was going great but i hit a wall with modding
i picked up a f2 header and fswerks auto flex pipe and am getting ready fo the install... i think
for my birthday my parents gave me a tune for my car... i was thrilled
my plan was to get 93 oct tune with rear 02delete but not im not sure
with driving so much i was rethinking doing the header install and just getting the tune
i have read that tune with just cai and exhaust is worth it but the header makes the whole package
so i either install the header and then tune or seller the header and flex and do the tune and get tint?
