Yep, just run the stock catted x-pipe with a Bassani Race cat-back. The tune will be spot on this way! And the HP gains from the cats being gone is minimal.

Called Bassani and they told me the 2010 is a different setup. They have no axle-backs/cat backs for it. I don't want to go with Magnaflows.. but it looks like I;m not having much of a choice..
Just put the kb2.8 stage 3 on and not to thrilled with the results. Even going with the 3.25 pulley to be on the conservative side, it's not even close to the numbers you have on the site. It was dyno'd on a dynojet which gives no load and produces higher numbers then a load bearing dyno.
your numbers are 658rwhp mine is 623rwhp and it running pretty lean too 12.8's with your tune.
I put the axle back you suggested on as well. Everything else is stock except for your kit. I changed the stock heat exchanger. Basically that's the only mod from your numbers.
I'm going to drive it around for a couple of weeks, maybe it needs to break in a little..
Well I just confirmed this, the 2010 is lower on HP. Ford changed something. Ken is tring to find out from Ford what they changed ( heads, cams, ect.)
Lower on HP, what are you talking about? Why would Ford have changed any of the internals on the engine? Is the exact same engine as the 07-09, they just slapped on a CAI and probably a different tune to get it up to the advertised 540hp.
Lower on HP with a KB installed, is that what you are talking about? Doesn't even make sense. Confused but good information to know before I upgrade my blower.

The 2010's are different. The programing for sure (knock sensors and a few other safety things) and obviously some other parts. As I find out I will post it.
Lon, That might be the belt. If you have been beating it up a little bit then the belt my have some slip spots.
I heard it at the shop, never questioned it. It's not like a belt slip squeel, it's like all the time. chirp chirp chirp chirp.. It's the belt KB supplied.. Doesn't feel like it's slipping. Haven't been beating it up. That video was the day after I drove it home in the rian ever so gently and then it was pulled out of the garage.
Maybe this is the problem??
I only went WOT after,,, a couple of times from mid 2nd to 3rd. Not yet in 1st.. Too chicken.. heh..
No it's not the belt as far the Horsepower being down. That is just the churp, The belt gets hot spots from the compressor and crank pulley. Then everytime those spots go over the supercharger pulley they churp.
2010 gt500 KB 2.8?
