Just a tease but these show up on Thanksgiving. I'll do my best to install an X-pipe, delete the cats and possibly add a muffler at some point before the New year.

I'll do a dyno before and after and I'm expecting decent gains. If all goes well, Jed hinted at a group buy like he did on

I think us 4.6 guys with e53's will have to use a custom secondary as the slope down is much more aggressive than on the sedans. That being said, these should fit the 4.8 and 4.4 as well so it could be a nice addition for those wanting a little more pep.
