Stage 4 exhaust
Wondering what you guys think is the best head pipe and Slip-On for the 107 with stage 4? Also true duals or x-pipe?
Thanks |

This is a stage 4 Road King Special with SE High flow exhaust/TTS tuner 124 hp/118tq with a little mod to the mufflers

Here's a LINK to Myths and Facts on Harley exhaust.
The Thunder Torque Inserts™ will provide more low and mid range torque and also deepen the tone of the exhaust(any exhaust, stock or otherwise) a bit, giving it a throatier growl. They cut back on engine pumping losses and reversion. Here's a chart taken from the report showing how the TTIs work- https://www.dkcustomproducts.com/med...Diagram_cr.jpg Best exhaust mod when comparing results per dollar spent(29.95) Here's a LINK to the TTIs. Hope this helps! |

Thanks for the replies. I currently have the stage 4 on a 17 M8 with Vance and Hines power duals and titan Slip-Ons, H-D high flow intake, it makes 118hp and 114tq right now. I want to go black and a have a buddy willing to buy my chrome stuff. Having the opportunity to start from scratch I'd thought I'd throw it there to see what others are doing for best overall performance.

I like that tuner,At a later date i will probably go to the TTS 200 cam and S&S cam plate and oil pump,but as of now my stage 4 has never run better and after what I have done with my SE high flow exhaust it really helped low end tq and boosted the HP also,It made me a beleaver in my choice of going back to it |
True Duals typically make more higher RPM HP but give up low to mid RPM torque, So what are you after? IMHO the original 2:1:2 exhaust makes for the best overall balance between HP and Torque on the M8 application, but if that's not the look your going for you have to do something else.
