Gutted 2nd Cat
It didn't change the sound much, turbo spools faster though. Lots of second hand exhaust gets sold in the classifieds, that's where I got the ZZP downpipe, your welcome to it for a mere 150.00. I never took it out of the box, I'm happy with the gutted second cat mod. These Flowmaster HP2 shorties sound good to me. I think Foxtrot raptor found a inexpensive muffler that sounder good, might pm him.

I made a hole on the right to match the one on the left,(multi-master) you already have what I went off of.....
It took a few check and recheck before I cut it out freehand, used the cutout to fill below. Planning on fiber-glassing it before we paint the cowl hood.
