either the Jackpot dynotune 4 inch or the Rush big Louie but not sure which baffle to get.

 

I have had Rush with the middle baffle
​​(2.5) I think and they sounded good. Certainly louder than stock but lacked that deep rumble. If I might add another suggestion, I now have Two Brother's 4" slip ons on my Street Glide and must say that they have a very nice deep rumble without too much noise. Also, I have the black tipped ones and somehow one tip got warm and the tip changed colors. TBR was great about replacing the damaged tip and mailed a new one out at no cost with no questions asked.

 

Ask Rush but they are probably going to tell you 2.25 for the stock motor. I have them on my 16 but I am not impressed.

 

I'm happy with my Jackpots 4" dyno tune. Excellent value for money, especially once you factor in FM's outstanding customer service.

 

If you go with the Rush Big Louie's I am pretty sure they come one way. Two different size baffles for right and left because of heat. You can call Rush and they will explain it better than I.
I went with the Big Louie's on my RGS and really like them.

 

You're partially right. I forgot about that. They sell them both ways. The ones for stock headers that have 2 different size baffles and they also sell them for dual's and more uniform flowing exhaust. The stock header flows more through the right can.

 

Thanks for the input. Mine has the stock set up

 

If your are stock with cat, Rush Big Louie SB2 is what you need.

 

Rush Big Louie, all the way!!!

 

Both mine have BL's with 2.25" baffles .................. sound great and they greatly improved performance with a stage 1! I ran cat on the 12' for a year with 3" baffles, it helped performance and I didn't really notice any change in sound going to stage 1 with the 2.25"
