My Cat shit itself and completely blocked up the muffler so i found out later on and its actually working out cheaper for me to get extractors and a new exhaust rather than the standard exhaust ($900!!).
I've been quoted between $730 and $800 for the following 2inch kit complete from exhaust manifold to tip:
2inch lukey tri-Y extractors $290
Universal Cat $250
pipe and labour $200-260.
you guys know where i can get this stuff cheaper? also any experience with this setup or any other info that would help.
I've search and read heaps on this tonight my brain hurts

cheers
