First question:
Anyone here with aftermarket exhaust system (im running weapon r headers + cat converter) have any exhaust rattle at idle? All my bolts have been tightened.

Can it be 'fixed'? My stock exhaust didnt rattle.

Second question:
My brakes are often squealy, but the pads (OEM) are all fine. What can I do about this? I don't brake hard and late.

A1 - What exhaust do you have?

A2 - If the stock pads have plenty of material left, you should first put on anti-squeal brake grease. If this reduces but does not eliminate then look towards the other components [eg. Rotors and Calipers]

1. did u bust your cat? - try hit it with a hammer or something

2. brake pads might be running thin or u might have a rock in there

Stock catback.

Is the anti squeal brake grease a temporary solution? Will it need to be reapplied later on?

I thought it was the cat so I tightened it up. And I dont think there are any holes in it or anything loose inside of it... but id probably have to get my mechanic to help me out. Would it have something to do with the cut and weld?

No, anti-squeal brakes are applied when new pads are put it, but depending on how the design of the pads/calipers are, some retain the grease better than others. Grease also overtime gets used up/displaced


I thought it was the cat so I tightened it up. Would it have something to do with the fact these extractors were cut and welded to fit a cat converter?

Curtis is referring to the inside of the CAT ie the matrix collapsing and ratting around.

^yep that's right.

was refeering to the core of the cat, apologies for not making that clear

Ok thanks

I see. I wouldn't know but I'll get it checked out. Thanks to the both of you

Race header + no flex pipe = Rattle, get used to it lol

it's not the exhaust/cat necessarily.

machine the disks

Thats what I thought but just in case i thought i might ask.



machine the disks

Noob question: can you expand on this please?

Mine doesnt have a flex pipe but rather has a bolt through a spring holding the flanges together. This lets the flanges move in out slightly and the whole mechanism tends rattle at low rpms. Probs hits some resonant frequency and the spring goes a tad nuts.

Fredoops means when machining the disk is to make the surface true/flat again. Brake Disks/Rotors overtime and usage can have imperfections that can alter the rotor's surface to be not flat. This can cause squeal but usually more associated with vibration/pulsation.

NB: IF you do machine the rotors, ensure there is enough material left, there are indicators to check this =)

ok thanks for that
