You clearly don't, as you can't distinguish between middle & rear mufflers Link to comment Share on other sites More sharing options...

And gave it WOT... You've probably f*cked your engine... Link to comment Share on other sites More sharing options...

Periklis Member 67 Member For: 14y 4m 25d Posted 15/09/11 07:46 AM Author Share Posted 15/09/11 07:46 AM ok guys, I had a proper look today and yes the CENTRE muffler was removed, yeah I know laugh it up lol... anyway had a look at the rear muffler and have no idea how I can take it off? from what ive gathered its either the cat or the rear muffler that could be causing this?

Take it to an exhaust place and they can do tests on heat etc to see where the problem is and replace accordingly Edited 15/09/11 09:50 AM by CBXRT Link to comment Share on other sites More sharing options...
