here we go again..since i had my k-tec cat back fitted i've been experiencing a knock from the back of the car..as usual its getting on my nerves :nope:....its great when its just me or one passenger in it but as soon as i have a 3rd person on board it starts doing my head in again..thought it was the silencers touching my difuser so got some washers to be fitted..i aimed to make a gap between them two parts a bit larger..job well one "i thought" but sadly it didnt work..
went shopping today and took my mate with me..just 2 of us in the car + our shopping..still does it when carrying weight..
i know it has something to do with my exhaust but cant,for the love of god,work out what it is exactly..
any suggestions welcome.
thanks
