If you are looking for the loudest downpipes with no CEL, go with fabspeed.

I recommend active because it gets the job done, it's less expensive, and it will sound as good as any other catted downpipe.
Thanks Mike! you actually responded to me on another thread that I thought was dead.

The only thing that worries me about fabspeed is that it might not pass emission here in Las Vegas so I'm leaning AA.

Lastly do you think I'll get more out of a jb4 with the lower cell count dp or is it probably negligible?
