Ok, I have had the magnaflow on for about 6 months and love it, should I consider doing a new catalytic converter(hope I spelled it right)? Also i am getting a tune up tomarrow and am wondering If I should do new wires, rotor and cap with the plugs???

 

I always tell people to go with a high flow cat only if the existing cat is bad. Random Tech, Carsound, etc. They all make decent high-flow cats for a decent price. However, if your stock cat is good, then I would keep it. You wont gain much.

Kinda depends on your mileage and vehicle condition really.

As for the tune up questions, well, that also depends on the condition of your vehicle. If the parts you mentioned have not been replaced in a long time, or you have no idea when they were - then go for it. I just hope you dont get ripped off. That stuff is REALLY easy to replace.
