i was wondering if i could get a hp estimate

1) 12 plate ff, afc ff, afc modded, air filter , and 4" cat back straigh pipe

2) same as above but with a 5 plate

thanx so much in advance ... i am building 2 trucks and wondering how much hp to expect from them

 

when i put the 5 plate in my truck in the middle there was a lil notice of power increase but not to bad with the 12 plate slid all the way. but with the 5 slid all the way it would be a good jump up after i get my tc im going to slide my 5 plate ff
