a midpipe/highflow cat pipe ?
It would be flanged where the stock ends are ( obviously) and have 2 bolts on either side. Making the swap from a highflow cat to a midpipe simple and requiring less then 10 minutes.

I found a place that can do a 3" mandrel bent pipe for $125 and I can get highflow cat cartidges for around $225 ( high heat.. so rotary OK)

Total cost would be $400 even and you WILL pass emmisions and 10 minutes later ( letting it cool no doubt) your back to your midpipe and making the big hp!

the advantage of this is a VERY VERY Simple swap betweenthe 2. Thats the objective! To swap between them as quickly and effortlessly as possible. There may be a brace that goes between the 2 end segments to make alignment even easier then before..

And for 5 minute swaps V band clamps will be an option but cost an additional $50/$100.. need to see what they cost each first...
