i am currently running straight pipes and frankly i didn't see any power difference (except for louder exhaust). is it really "ok" to run without cats? let me know how you'll do yours without triggering the SES light. mine goes one every couple of days and i just reset it with an Actron. any info would be awesome. oh and GL with the sale....

im going to turn the rear O2s off, i dont care about performance much. i dont see it yielding anything, id just rather have straight pipes and $1500 in my pocket...

Wow, Texas must have a pretty relaxed inspection sniff test. I don't think that would ever pass in MA.
