I'm a fan of Rinehart's 3 1/2". I can't tell you how the 4" will sound.

 

To get idea what like what did you not like about the 4" Jackpot mufflers post headpipe swap?

 

Don't mean to hi-jack the thread but I've been wondering the same, and same as the op, don't want too loud...just a nice low rumble at idle & a bit of a bark when you get on it.

As another poster has mentioned...stock header without the cat (which is what I currently have) & stock slip ons is definitely louder and better.

I was thinking next step would be the catless header (which I have) and V&H Monster Rounds. Anyone running this setup...how's the sound?

 

V&H Monster Rounds. Enough said.

 

I like my Rush Big Louies with 2.00" baffles. That I like how they currently sound isn't the important part. What matters is that one of the reasons I chose the Big Louies is because they have easily swappable baffles. I originally got them with 2.5" baffles and it was just too much volume with the catless head pipes. I ordered the 2.0" baffles and it was just right for me. So...look for something that allows you to tune the sound!

 

Jackpot 4" sounded good before. Now they do not seem much louder but the tone changed. Almost sounds like it chugging. Combination of pipes and cams I would guess. Want a deep tone without being obnoxious. Pro touring pipes are 85db at 2k rpm with the cap. So without they were a little loud for me.

 

Had jackpots now have Big Louie's with 2" baffle.

 

I have heard good things about the Big Louies and I am very happy with the 2:1 Rush on the wifes Fatboy. It is hard to tell on the internet, are they a deep tone? How did they directly compare to the Jackpots?

 

put some of fuelmoto's new e-series on it, the are tuneable by the amount of disc's
