my exhaust has been rattling for a while now and after doing some reading, if its the cat, it can cause the exhaust to block and cause back preasure hence killing performance.
got a quote for 260 to replace the cat @ right price exhaust. i have no idea really. been searching the forum and people have been talking about cat-back system and struggling to work out the difference.
not sure if i should just replace the lot.
Anywhere good in brisbane, south side
