I have the Nino's Auto Accessories Uppipe (an exact copy of the perrin) and the godspeed catless downpipe. It was roughly around $600 for this set up. The godspeed downpipe is a bit pricey at $400, but it is OBDII failproof. They weld a nipple onto the pipe that your sensor goes to and makes your ECU think that it is a cat. No problems whatsoever so far, and the fit is absolutely perfect!

500, i thought it was 5000, so what downpipes retain the midpipe cat.... all of them? im looking to keep at least one cat.... there are so many more companies than im used to with exhausts...with my focus it was about five choices total.

what about the autospeed combo advertised at the top of the page, are these quality exhausts?

edit: with the high flow cat in the dp, how much gains should i expect to see?
