I have a twin 3" cat back system. there seems to be this rattling noise at 1200 rpm etc. but everything seems quite tight. car has 300 hp at the wheels. can this have collapsed the cat? I just read somewhere collapsed cat makes rattling noise?

anyway thinking of highflow cat installation along with few other mods.any tips for cats? cheers Guys

mate no point puilling the cat out, if half of it is already in the rest of your system!

see if you can split your exhaust into sections if you really want to clean it out.

but this is a *beep* of a job without a hoist.

Just checked under the car.exhaust has no rattles. The noise happened just a few weeks ago. I thought the engine was losing its bottom end after some mods.wog cooler,72 lb injectors typhoon intake cat back and tune.300 HP at the wheels.I drive the car every 2 weeks for about 30-40 kms but like I stole it.half the sh*t it gone probably and free flow too. Have some more parts to fit.soon.maybe get a venom to match the 4" dump I have.

A tech question. If my cat had collapsed and car has been tuned if I change the cat to a venom or ballistic 4" body do I need a retune immediately?The issue is I live 1200 kms from Perth.I have been driving it like I stole it. No issues so far though.
