I can't afford a full catback right now, so come spring I might just get a Flow 80 series.
What is my best bet for spark plugs?
Full catback is a waste IMHO, but a very high flowing muffler with minimal pipe bend would help. Maybe a high flow cat? I suggested NGK or Autolite plugs, with 2 heat ranges colder, and a 180* thermo for the 3.5" pully. If you do get all those mods tho, the 3.4" with the Sunoco 94 gas will run just fine, and there will be a noticeable difference, especially in sound
