I was told at RP that I could run a stock manifold with a Bonex straight pipe. But I dont think there is a backpreesure tube for the air pipe. At least not in the picture. Anyone have this setup? Can this be done?

by straight pipe are you reffering to the bonez midpipe that goes from the exhaust converter to the y pipe? If so, no there is not place for the pipe that puts air into the cats, you wont need it, especially if it is an s5.

 

After the headers were on, I had mine straight through for one day. You won't believe the loud... Harley Davidson bikers wont believe the loud!!

 

I guess with the stock collector, it might be tolerable.

 

im retaining the stock collector on mine..im not hardcore enough for the headers plus i live in Northern VA, the cops up here are lots of the time asses cuz of all the rich people..
