Dum-Dum's Black Rallye

You can get decent 2nd hand whole cat back exhausts for 100-120.

You cant, they are all magnex or abused.

Actually, you can.
My full Mongoose was 110, I've seen full scorpions go for anywhere from 90-120 in the last few months. My current exhaust cost a bit more than that but I had a fair bit of fabrication done.

You just need to wait and keep looking at that price. I'm happy to let you know if a nice one pops up on the gti6 forum if that'd help. However, you've mentioned you don't have time to wait, which is ok. They are out there though.

I've never used a sportex exhaust so can't comment on them.
