Thought I would share my thoughts on the Rinehart 2 into 1 which I have just fitted.

So my 2016 Road King has se 255 cams, fp3 and high flow filter, thats about all engine wise.

I had stock headers and V and H slip on monster oval mufflers but have wanted a 2 into 1 for a while...finally got the cash so ordered from Rollies Speed Shop in Brisbane, very good to deal with, shipped it to Harley Heaven quickly, 3 days .

Fitted it up, great packaging and finish, well made product, the only thing was the diameter of the muffler is exactly the same as the header pipe.

Had already smeared high temp silicone inside it, you can imagine the words which came out after I realised I had to belt it with a nylon hammer to flare the mouth of the muffler...

It was a total bastard to wrestle that muffler on,this is the only complaint I have. Had to get it on the header bit by bit then flare it out using the header, otherwise I would not been able to fit it on. Not exactly what I wanted to do but necessary.

Anyway I went for a ride into the hills this morning, and WOW what a difference ! Sounds like an effin hot rod now when you crack the throttle !

Better idle, smoother acceleration, more torque according the butt dyno, it goes like shit off a shiny shovel compared to the old system.

I have run a Thunderheader on my old Street Bob and a Supertrapp on my old evo Superglide, so I am no stranger to 2 into 1 systems.

If you are thinking of getting a 2 into 1, all I can say is DO IT, if performance over looks is your priority.

By the way, the Rinehart is a lot cheaper than say an S and S system by a lot.
