Looks nice... How's the pricing on this thing?

But aren't all resonators "high flow"?

It suppose to use the stock front pipes with the primary cat, and since the O2 sensors are located immediately before and after this cat, and they are what throws the CEL. Since they are left untouched, no CEL.

Now what I am wondering is if you are required to cut the stock mid-pipes off from the front pipes, or if there is a way to disconnect them.

You need to cut the OEM pipes because they are one piece from resonator up to headers.

But by leaving your stock primary cat you definitely won't get a CEL and you will pass inspection

It would be interesting to hear it on a stock exhaust.

Looks like another X-pipe that requires cutting.

Is Riss Racing the only x-pipe and HFC's that are 100% bolt-on?

Guys, every single X pipe that doesn't also change the primary cats is NOT A BOLT ON. You must cut behind the primary cats and attach.

If you get a complete system from AA, Encore, Fabspeed, Riss, etc....., that includes either test pipes or HF cats, then these are bolt on.

To recap, no company has a bolt on Xpipe that attaches to the stock cats. None. Zero.

Somewhat correct. If you look at Riss Racing's setup. If you just get their X-pipe is deletes both sets of cats, it includes straight pipes (or HFC's for an addtion $499), best deal out there. There is really two sections to their X-pipe, with flanges on both ends, so it is 100% bolt-on. So yes you are correct if you want to keep your stock primary cats, you will need to cut, but Riss doesn't even have the cutting option. You can literally unbolt their full exhaust in your driveway, no exhaust shop needed.
