I installed it the first time without a gasket and felt a bit of a leak after a few days. Undid the joint and used a high temp silicone liquid gasket. That seems to have done the trick.
If you had checked Steve Schwing's Fokti on his Forge install you would've seen where you needed to snip the heat shield.
I love the tips too even with the cheesy blue flame stickers.
Where did you get the extra bracket and hanger from? I'm checking with the local dealer on pricing.
