Hi, I'm planing on having a muffler shop do a custom exhaust system for my 95 240. I plan on having piping from the cat to the muffler. My friend told me to go with 2.25" piping but I see that plentyof 240SX owners have 2.5" piping. My question is whether to go with the 2.25" or the 2.5" piping. I have no other mods so far but I plan or keeping it "NA." My mods in the future would inlude the typical intake system and headers. What would be best for my situation? What is the advantages and disadvantages of both 2.25" and 2.5" piping. I plan on having the exhaust done in the next 7-10 days.  Any suggestions would be appreatiated.
