So far I would say there is defiantly an improvement in torque and acceleration. She just charges harder now. The increased performance from installing the headers was awesome but with these it just got even better.

Now the question is what performance chip do I get for my car now. There is Dinans, Turner has theirs and BavAuto has theirs. I figure with the Afe intake and high flow exhaust and headers with would be time for the chip. Any suggestions?

Weasel how much work is involved in putting on those bigger fuel injectors?? Time? And I will go and put Her on a real dyno and find out how much HP I have. I am curious with deleting the cats and headers there should be a nice gain. But who knows. I do like driving my X a lot more now!!!
