Preliminary report:
This kit is the diffuser discs only, intended to add onto the end of a tailpipe. After I got around to messing with it, I saw a couple problems right off the bat. The nuts seem to be the wrong size thread for the ss bolts. The bolts themselves are small diameter, and don't look like enough to support the weight of the discs (under hard road use) once the thing is assembled. The kit only came with very general instructions, so I had to hunt some down online:

The kit also has an optional black shield that deflects the exhaust toward the back of the assembly. Now I would have returned this kit, but I had a flange welded onto the inlet before I got a good look at the hardware and all. I got some ss couplers to use instead of the mismatched nuts thinking that would make the whole thing more sturdy and less likely to have bolts seize up.
The intention was to be able to run it on the way to the track, then remove it for racing. But right now I'm not too enthused about trying it at all, since the Borla "resonator" is in place and sounding decent.
