wilo Posted October 2, 2016 Share Posted October 2, 2016 (edited) i have this annoying rattle on high revs acceleration and deceleration. sounds like a loose heat shield but cant pinpoint where . my car has a full miltek system thats been decatted and just had the resonator removed too . the noise was present before i had the resonator took off but seems louder now . any ideas guys ? oh and the rattle is a tinny noise that increases with the revs ..especially on deceleration Edited October 2, 2016 by wilo Quote Link to comment Share on other sites More sharing options...
Wizza2000 Posted October 2, 2016 Share Posted October 2, 2016 Shields on cats, mine rattled at above 2000rpm and when de-accelerating, I removed mine as they were not in a good shape when I replaced exhaust system and cured my noise But you know cars my issue might not be the same as yours but worth a check and you might be able to save yours and get them sorted Quote Link to comment Share on other sites More sharing options...
Richf Posted October 2, 2016 Share Posted October 2, 2016 Best bet is to get it on a ramp and bang each box with your fist , its not unknown for baffles to break up and rattle over time Quote Link to comment Share on other sites More sharing options...

Richf Posted October 2, 2016 Share Posted October 2, 2016 So when you say decatted you mean the cats have been gutted rather than decats fitted ? Quote Link to comment Share on other sites More sharing options...
wilo Posted October 2, 2016 Author Share Posted October 2, 2016 So when you say decatted you mean the cats have been gutted rather than decats fitted ? no it has proper aps decat pipes fitted..basically my miltek system is straight through barring the back box Quote Link to comment Share on other sites More sharing options...
Richf Posted October 2, 2016 Share Posted October 2, 2016 unlikely to have cat shields with no cats fitted Quote Link to comment Share on other sites More sharing options...
