Even if you hammer in the heat shield they still hang a tad low and will rub on bad speed bumps and such. I loved the way they sound. The only advantage of going with a Fabspeed setup is with the 02 extenders you can probably get by without a tune. I would prefer to have the cats in the secondary position as I feel there is less turbulence after the header that way. If you want to get a tune down the line I would pass on the Fabspeed and go with a testpipe setup or go with the cats in the secondary position.

Just my .02
