Probably will melt your signal, not speaking from experience but lots of other folks on this site with same exhaust and melted signals. Looks great, good luck!

 

those signals in the picture are actually replacement signals, they are a lot smaller than the stock signals and I'm fairly sure these ones will be fine. I went for a good 1 hour ride today, after my ride I felt that turn signal and it was cold, unlike the muffler. Surprisingly it was in the 60s here in southern NH today but I will be keeping an eye on that turn signal.

 

those tires you will like, and yes the 4.60's fit just fine in the rear and the 3's fit the front. I used to run them on my 09sf. Great traction on the pavement and hard pack dirt with a handful of rocks thrown in, loose dirt was good as well, very predictable. I hated them in snow, instantly packed up for me but others like them in snow. Had over 5000 miles on them before replacement became a good idea, still had enough tread to work on pavement without issue.

 

Thanks for the input for those tires! Yeah they looked like nice tires for the price, I'm still unsure if I want to do the 4.6 or 5.1 in the rear, I'm leaning more towards the 4.6 for the fact that it will make the rear end sit lower than the 5.1. Only reason I need that is because I'm about 5'7" and if it is any higher than stock then it may be a little bit of an issue haha...

 

Bikes all done!
