Well My cat finnaly died last night and i need a new one asap, and i need a new hi-flow mufler as this one is damaged by scraping, how much am i lookin at for the cat, and where would i find a new hi-flow muff?

Chears

I got a really cheap exhaust system from benalla in Country VIC which probably doesnt help, But it was a redback 2/12 inch system with 2 hi-flow mufflers for about $180 off the top of my head. i got a magna flow hi-flow 200 cpsi metallic cat for about $120 but had to buy my own flanges and weld them all together.
I thought it was really cheap as i got quoted for the whole system 4499 pacies, hi-flow cat and redback 2/12 system for about $1200 supplied and fitted. Got the pacies for $410. Hunt around dont get stooged by the larger brand exhaust shops the little ones can still run a good bargain.

look on google for aaa exhuasts there in SA and there good, or henrich tunning and performance

chears 4 that, yer ill prob go down ther tomoro after tafe, as i realy need my power pack
