ok im not sure i know what i want to do and i think if i knew a few answers i would know more

ok i want to order a down pipe cti or zzp my main problem is i have stock exhaust with just a muffler only. id like to change to a 3" exhaust someday and don't want to waste my money on a 2.5 outlet down pipe..is there a big difference between 3" exhaust and 2.5" exhaust?

also since one day i want to get headers but cant afford to now am i wasting my money buying a down pipe? since some are combos?

next question will i have more power going cat less or is sound the only difference?
Same thing with 3" exhaust is it just sound or is it power as well?

sorry if these are common questions i searched for a bit and didnt find my answer.

 

get a cia header or ottp long tube going catless will yeild some power make it louder 3in is yhe best way to go if your going to mod in the future but i would suggest you do all the cooling mods first then worry about exhaust

 

ok well like i said i dont have money for header now i have a 200 dollar budget and was just going to get something small. i thought id get downpipe now then save for the headers. but whats the best cooling mod for under 200?
