Dazzi Posted August 28, 2008 Share Posted August 28, 2008 I installed a 2nd decat a while back and have experience light vibration through the gear stick when i get between 3200 - 4000 revs. On installation I noticed the gear box bracket for the exhaust was broken off so is it possible this could be the cause? It's only between 3200-4000 revs as stated above and happens in each gear which is odd. Quote Link to comment Share on other sites More sharing options...
Dazzi Posted October 18, 2008 Author Share Posted October 18, 2008 After fabricating an exhaust clamp I also get a vibration around 2200 revs. I think I will install the stock 2nd cat and see what happens. Quote Link to comment Share on other sites More sharing options...
JustGav Posted October 18, 2008 Share Posted October 18, 2008 It will be due to resonance at that certain RPM. You mention the bracket is broken, that is more than likely the cause. Quote Link to comment Share on other sites More sharing options...
