Woooo, my fuel mapping is riiiiich. With the baffle out, the bike is banging and popping on decel like a mexican bandito firing in the air and the sound of it running down the road is like an ogre gargling jet fuel. I need to get this thing to a dyno asap! Oh, and the exhaust fumes reek of fuel. That was my first indication (other than the stock header and my previous exhaust being completely black inside). I think I'll call the local Triumph dealerships and ask them if they can recommend anyone local so I don't have to ride all the way to Houston and back.

Not sure as we do not know what changes you have made, but a couple of thoughts...

Popping on decel is a LEAN condition on partial throttle (assuming no pipe leaks), not rich. In fact, to cure it you need to richen the idle and just off idle sections of the curve with partial or closed throttle positions.

As for the excessive smell of fuel, we don't know yet as we do not know what you have put in there for settings or what box you are using?

But you have to admit that at night, a high rpm decel run can make for some VERY cool flames out the pipe! Get your camera out at least once before making it correct!!! ;D

Do I need to use any sealant on the slip-joints? I just clipped them together without any wrap or goo.

Yes, you should be using high temp silicone (Hondabond (Honda Dealers - great stuff, kinda like Duct tape!), Yamabond (Yamaha dealers), Permatex Ultra Blue (ACE Hardware, etc), etc) at all the slip fits. This will not only help seal any of the "pinhole" leaks and/or sucking in of air, but also makes it much easier to disassemble the pipe if you ever need to take it off again...

Not sure what "black Permatex" is, but it appears to be "adhesive", which means glue.

If I am reading the package correctly I think this is NOT what you want to be using.

You are just looking for some silicone to seal with, not create a bond.

Please make sure you have the right stuff, or use the Hondabond / Permatex Ultra Blue...
