mine was doing this and i found out it was the exhaust hitting the back of my car under my bumper. so the angle grinder came out, and no more banging

Cheap solution: fix some rubber on rear beam where the exhaust is to deaden the sound

Mine is literally the exhaust pipe touching the rear beam, dont have the problem with the exhaust clamp. I need to get a custom exhaust made that wont touch the beam when I have people in the back

get a band type clamp instead it's not this but same principle:

most auto shops have them instead of the big thick round ones, you'll get about 5mm more clearance which shud be enough

Oh - Mine came off the rubbers last nite. It's really good. 20 miles with the exhaust sat on the rear beam :) Donk Donk Donk Donk Donk!

It's the exhaust banging on the rear beam. Think you can get the pipe bent to cure it though!

most of the tiome its the u b racket that holds on the backbox. it can be re-possitioned / ground down to stop this.... is a b**ted i drove from eastbourne to canterbury and back last nite [about 140 miles] with it clonking does me in!!!!! :mad: sorting it this weekend hopfully if i get time...

ollie

mines is lowered 40mm on Koni adjustables but my brother done this when he had the car roughly 5 years ago so im wondering if there just worn and need new stronger ones?

Mine does this and always has done it ever since I lowered it. Everytime I have passengers in the back it rattles on the rear beam. Was fine before it got lowered

from what i can see or feel i think its sitting correctly, i would say if anything its sitting closer to the front but not by much if at all. im just thinking about the rear suspension but how do i tell? cant be arsed taking it to a garage.

check that exhaust or any part of the metal brackets that it hangs off aren't touching inner skin of rear bumper,

system may right be sitting far enough up the car if you know what i mean

when car has a heavy load there is a knocking sound coming from the rear of the exhaust. i think it maybe rubbing the rear axle when iv got passengers in the back ( no posts telling me to take the rear seats out please lol)

when the car is empty and im looking underneath, there still seems to be a lot of space between the exhaust and the beam so im wondering if the rear springs needs replaced or something.

However, this only started happening when i got a sports cat and stainless steel downpipe which makes me think that the exhaust isnt sitting right but then again it should still make the noise even if there isnt a heavy load.

The noise seems to be worse when going up hill too which i beleive is just because there is more load on the back.

Any help would be great people.
