You need a new exhaust gasket....from the sound of it.

It started with a little back firing for 2 weeks and tonight it sounded like my pipes blew a hole out of it ! I've had the bike for 7 yrs and this is the first time I had this issue come up !

A leak in your exhaust can / will cause backfires. Any unburned fuel getting in the system from a rich intake mixed with oxygen from the leak and you get a nice big bang. Replace the gaskets at the head pipe and joints and re-torque the fasteners and you should have a pretty easy fix.

+1 on that^^^

Had the same problem here... A year ago my bike started to bang and pop and run a little ruff and also sounded louder.
I started to search around and found all exhaust gaskets where burned up and the whole system was loose...

All new gaskets in and everything nice and tight, no more exhaust leaks or pops or bangs and she ran smoother..

Now that was a year ago and just a month ago now I had my exhaust off again while doing some other work and I inspected the rear down pipe gaskets and they looked like they were burning out yet again...I put new ones in again just to avoid any problems down the road...

I did see on these pages that the Rc does eat exhaust gaskets rather quickly.

I have put exhaust gaskets on my yearly to do list from now on...

No Novels!

Fricken GOLD battery!

if you're running stock headers you need one for the head and one for the join in the pipe but you may as well replace the front head one at the same time
and maybe do the link pipe ones as well
