Ahh The Master Grumpy Beat me to it....Agreed If your not confident,just put the screw in muffler on less risk of damgaing a good engine. One other thing..NEVER try and remove a stud from alloy when its at red hot temps it will strip the thread straight away and will need to be helicoiled,costing you more money for a kit. always cool before trying to remove,a hit with a flat faced hammer occassionaly to shock it may also help...Youll be fine as I just did mine and also had to remove the screw in muffler thread which was actually harder..man it was in tight!!! lols good luck!
