I personally have used the magna flow,I even had a cat back made using 2 3/4 pipe. I would say 90% of the crossfire owners have come to a decision to remove the rear cats,, and another 40% come to the conclusion to remove the resonator along with the rear cats, removing both rear cats and resonator,could give you about five Horse power increase , none of the others can even come close to the five Horse power,but if you would like to waste money than buy the magna buy the others,and when it's all said and done take your rear cats and the resonator off and Be happy. jim
Let me make a slight addition to this, I have never used the headers but did have Needswings downpipe with the elect. cut outs (no cats) now if you get the headers from Needswings, or the downpipe with The electric cut outs, you will notice a difference in power.my top end went up by 3 to 4 mph and that = about 10 to 15 HP gain. jim
