I currently have the fullsac recores and am thinking of switching to either rinehart 4"slip ons or S&S grand nationals. I'm trying to keep the same level of performance or better, but get a more deep rumble instead of the higher pitched sound from the fullsac recores.
Anyone have any experience with any of these and have any feedback? I'm trying to keep the same out similar baffle size to more closely match the tune I have.

 

never owned but friends have and heard many and for my ears, and sure I'm not alone, Rinehart just gets it, does it right..that Harley sound so many admire so much

 

I’ve run Rinehart DBX 40’s, and I had Fullsac recore my stock exhaust on a 2020 107 M-8 with their 2” baffles.

In the past they had, I think, 1 3/4”, 2”, and 2 1/4” baffles. Which size are you running?

The 2” Fullsacs sounded better than the Rineharts to me, and with better performance, and not quite as loud, and the Rineharts sounded pretty dang good.

 

What bike/engine do you have? An M8 with Rineharts needs at least a cam or it sounds like a 1934 John Deere farm tractor.

 

Sound is all about the cam choice, is this for a Milwaukee 8?

NO exhaust is going "rumble" unless you change the cam. Have you already upgraded to an aftermarket cam? You mentioned performance, so I was not sure.

Having said, while I really love my 4 inch Rineharts (and my aftermarket cam) I needed to install the Fuel Moto tunable inserts to maintain the bottom end performance.

Rineharts are one of the best sounding cans available, but they are one of the worst for low RPM performance on the M8. After the inserts are installed, and a good dyno tune, all is well

 

I have had both Rinehart 4" dbx and the S/S GN and prefer the S/S. Rineharts were to loud for me.

 

I have an 18 roadie, rs468 cam, ventilator ac and decatted stock head pipe. Currently have 2" fullsac recores, and before that had 2.25" recores, which was dyno tuned with.
I just find the recores have a higher pitch to them that leaves my ears ringing after any highway riding, and I wear a full face helmet. I was thinking if the tone was more deep and low pitched, it may not be as bad after longer rides.

 

I had Rineharts on my last bike,it was true duals not just slip ons and they were down right obnoxious.
My riding buddies didn't want ride behind me. lol

 

I had 4" Rineharts on my 2015 103 with fp3 tuner and Vance & Hines power duels I thought they were great. Loud when you wanted and nice for cruising. I had 3 1/2" Rineharts and true duels on my 1999 95 big bore and that thing would give you brain damage. LOUD

 

Check out the KhromeWerks cans with the louvered baffles.

These are what I am going with next, with either the Fullsac or FM XXX header
