I got 06 Roadking EFI Im trying to figure out whichslipone muffler will be the best/loudest for my bike ...Also which air cleaner do you guys suggest....This is my first harley....I cant really afford a full header system now....thx

 

Just picked up my '06 SG with Rinehart Eagle beak slip-ons that I ordered through Dennis Kirk. They sound really, really deep. There is a drumming percussion to them...a big bass effect. Had Samson True Duals with fishtails on a Heritage, and this beats them by a mile for sound.

 

I just put V&H classic slip ons on mine and they are sweet! I'm also going with the dresser duals this week. I have the arlen ness big sucker. I have read that it is way better than the SE air cleaner kit. Just remember that if you put the air cleaner kit on you need to put in a tuner for the ECM. I went with the V&H Fuelpak becuase I used their pipes. We'll see how it works here in a little bit.

 

Go for the Bub Pipes, Rinehart or a Samson pipes with a megaphone design.

I have the 2 into 1 Thunder-headers but they are a complete system and they are not really loud.

Rev up!

 

Hooker tuned flow, Louder than all the ones sugested and have a low great sound. But these can be adjusted from super loud to just loud in a few minutes. Another + if you go with a pc111, they have a map for this exact aplication.

 

Khrome Werks Lite, one piece construction, great performance, great looks, cheap and deep loud bass sound.
They are tuff to find ,keep looking.
