well here is the deal...............im working on my car and i realize i have no clue what exhaust stuff i going with........here r the mods that i have 2 factor.......

ported head
ferrea valve springs etc.
3" intake
the new Harrop tvs blower
and so on.........

all that being said i am thinking i will have 2 go with all 3" exhaust...........is that wrong? if so r there other options other than Tag,hahn,and vibrant.......those r not what im looking for look wise..................also i am not quite sure on a header. i was thinking about the ZZP mid leght header down pipe combo(1.75" prim. and 3" down pipe) but r there any other headers that can flow the same.............

 

3" would definitely help after headers, ported heads and larger blower. Customtubesinc.com This is where i got my 3" catback, i heard their headers are pretty good too.

 

i run the cti header and dp i would put it up against the rest

 

honestly, unless its a really shoddy company the diameters are all that matter perfomance wise. HOWEVER, sound does change from company to company.
