will de catting your stock header and running rinehart dbx45 lower your back pressure too much?

 

You'll maybe loose a little on the lower end torque but that can be fixed with the fuel moto tuning baffles or like I did is modified the Rinehart baffle to add backpressure.

 

Backpressure is a term that might get you shot around here

Yes, the Rineharts are best performing when used with a tuneable insert like the Fuel Moto 6" insert.

It works well, you can ditch the heat of the cat, and not over-scavenge as you would with a wide open pipe and no baffles.

I run them, they sound great. There are better systems out there, it just depends on what your goals are. Rineharts with a good cam do sound great

 

I did just install a woods 22xe and it sounds great. and a fuel moto map. Only thing i didnt install was the baffles. And im not sure how much to bend to increase/decrease back pressure.

 

Which baffles? The DBXs have a perforated core (baffle), you left those out?? Put them in...stat.
do you also have the Fuel Moto inserts I mentioned?

 

The baffles in the slip ons are the ones that came with it. I never removed any baffles. I have the 6inch fuel moto baffles on hand, but not installed, didn't want to create too much back pressure with the rinehart baffles and the additional FM 6inch baffles too. Do I need both or will the rinehart baffles be enough?

 

You have to run both. You just drill a hole in the Rinehart baffle, and bolt in the insert. You can open the FM insert tongue all the way. You will not be disappointed, especially with that cam.

You can reach out to FM and have them send you a tune for the inserts being installed, it will run just fine.

 

Thank you. The tune they sent was for the baffles installed. I just wasn't sure where to adjust the tongue to. But you suggest open all the way making it a straight pass through?
appreciate all your help. Thank you

 

No, I meant bend it down until it touches the end of the tongue. Rineharts are wide open, you need the inserts to keep your torque.

You can play around with them later. I have mine half open, my buddy with the same cam as you has his open like I mentioned above, it's a torque monster.

 

What did you do? I have DK torque inserts in my Dyna with straight shots and massive differences there..

I have rinehart's on the RK and was wondering if I could ad those. Rinehart didn't understand why or what I wanted to do with there baffle for more torque
