IS it worth shelling out the money for a random tech hi flow or would a magna flow be just fine? also i plan on getting 2.5in piping the whole way so do i need 2.5 inlets and outlets on the cat?

 

Personal opinion a magnaflow would be just fine, radom tech would help with lots of mods, but until then you won't see much of a difference, again this is just my opinion.

inlet/outlet depends on your header, if your header has a 2.5" outlet then yes you will need 2.5" inlet/outle, if not then it's most likely 2.25" inlet and 2.5" outlet.

 

well im planning to get dc sports 4-2-1 ceramic. does anyone happen to know the specs on the outlet for the dc header. i got have a 95 with a jdm d15b engine swap.
