My Blaster is coming together just fine. My question ..... is the rubber coupler necessary?? if so, what kind of temps are we talking about??? Hopefully in a few weeks my Blaster will roar to life! Will keep you all posted.

I'm running a cascade innovations clamp on my FMF system.

Yes it is very necessary. The coupler is a sealing point for the joint preventing any leaks which can cause lean conditions. Rubber is not a good idea as it breaks down, cracks, and dry rots. A high temp multi layer silicone is best and will last a long time and be most durable. You want at the very least a 500° rated silicone, it will never get that hot but at rating your not putting the material to its limit point constantly.
 
ok then... I will have to purchase one very soon. My Blaster is one major piece away from coming alive! (besides the silicone coupler.) Thank you for the info. Will post pics soon.
