speed daddy headers on n/a engine

i bought some zzp mufflers from a guy on craiglist and thought it would be a good idea to do whole stainless exhaust. my question is i currently have a n/a 3.8 but i plan on doing a engine swap some time into the future would there be any drawbacks with a 3 inch exhaust on a n/a engine for the time being
 


real quick second question besides the speed daddy headers and mufflers what else would i need to finish the exhaust
 
I never noticed any draw backs from speedy daddy headers on my 3.8 n.a engine, only power increase, I didnt lose any bottom end (that I could notice) and before the headers I had a 2.5" downpipe.
 
so no big drawbacks so speed daddy headers the mufflers a new flex new band clamps and thats all i need for a new exhaust
 


Nope it will sound good, only concern id have is zzp muffs+headers=drone
I have a video of my headers if you like but I got a different glasspack and muffs
 
keep your stock resonator or get the longest glasspack possible, I put a 26'' long glaspack in mine, it stopped the rasp/popping noises at high rpms by alot.
page 11 of my car thread in my signature there is a video of my exhaust without and with a glasspack.

thanks that helped my decision out alot still not sure if i need any other exhaust pieces besides the headers and mufflers ...i dont see the y splt in the speed daddy kit
 


It bolts up just like the stock manifolds and downpipe does all the way to the resonator.. Now beyond the resonator nothing will change unless you change something there
 
ahhh very good sir...i'm in no way a car guru pardon my lack of knowledge my brother in law gets tired of the questions so he tells me to do the research the he throws everything on for me
