This is my opinion about the 2.5 in performance baffles. I have dresser duals also. Took 20min to do the install. Fit just fine. When starting it up, the idle is deeper sounding, bassy sounding, not really louder. When taking off it has that deeper sound but still not much louder. It you hammer down on it, it sounds like crap. Like it has a fluttering sound. Even the wife noticed something was wrong and she didnt know i had changed them. The standard baffles are a lot louder hammering on it. Cruising at 2200rpm it is deeper sounding, again not much more louder. Fuel mileage seems to have dropped, not sure why. So what did I do, took them out and put my standard baffles back in. That's how much I liked them. Hopes this helps anyone thinking about buying them. I might try them again after I install my cams and see how they sound.

 

I just swapped for the 2.5" baffles recently also. Have the S&S Power Tune head pipes & 4" Rinehart mufflers. The stock baffles didn't do much for me. The 2.5 was absolutely perfect and really woke these 4"ers up. I'm thrilled with the purchase and won't be going back to the stock baffles.

 

Thinking about getting these where did you get them please?

What size of baffles do they come with stock?

 

2.25 stock which is great as far as performance goes with 2-1-2 set-up. The 2.5 baffles will give you too much volume and hurt the bottom end tq.

 

It makes sense.
I had a gain when I put on RH slim line duals and 4 inch slip on's compared to the stock non-cat and RH 3.5 slip on's.

 

Interesting thread.
I had asked Rinehart on their Facebook page last year...they just said it would be louder. Which I can handle, but the sounds glider1993 describe I know. I've heard cars make the sound. So I am at a crossroads....lol.
