although lengthy, i hope my response helps you with your decision. Good luck. Oh and dont be suprised if u get a CEL (Check Engine Light) even with a HFC. I didnt get one, but i have heard of others that have. Should easily be fixed with a o2 sensor defouler. Test pipes may not always be so easy to fix. Again, good luck

 

and dont forget, motordyne is also coming out with new test pipes and has a high flow cat out.

 

i still another month to decide what i want to do. its just soo hard to decide.

thanx for the help guys.
