Definitely the latter.
You get the lower cost and better gains of test pipes but you are still open to using the XYZ catalytic converter, resonator or straight pipe. Which ever you need for your application.
Switching out modules on the XYZ is exponentially easier than swapping test pipes for regular HFC's. And the XYZ HFC costs about 1/2 as much as regular HFC's.
If you ever plan to take out your stock cats, the XYZ (with all things considered) is a lower cost, higher performance and much more elegant design with options.

Hey everyone, I picked up the MD shockwave Dual Ti cat-back exhaust system.
Here are some pics, and you will not believe the gains I got with this! I posted the dyno's up as well so you can see for yourself!
We ran 3 dyno's on stock exhaust (w/test pipes) and 3 dyno's on MD Shockwave Dual Ti (w/test pipes)
Greatest investment ever! I look forward to what's next from Motordyne!

for some reason that seems low to me espcaliy the toruqe
but still nice set up
It all depends on the dyno and the calibration. I hit 254whp with only a lightweight flywheel.
Also, my ride is 5AT

Here's a youtube video of the dyno

yest test pipes make a lot of difference.
I believe Cubanl81 was going to take some better videos but I think he's been busy
