I put a VH fuelpac and a Arlen ness big sucker with rush slipons with 1 3/4 baffles on my wifes 07 Heritage Classic. the install went very well and easy for all the components. The bike sounds much nicer than stock with a noticeble change in power band. the only negitives are the base idle is now low and some gurgleing on decel not popping but gurgleing.
cant tell if mileage will be better until I run a few tanks thru the setup.
Would I recommend this setup....Yes, simple and Big difference.

mine does the same thing, even a little pop on some gear changes..
picked up more Hp than Tq

 

you'll probably get worse milage now. You've richened up the fuel mixture.

 

Yea your mileage will go down, give the Rush's about 100 miles through them then they really open up.

 

I love a bike that gurgles on decel. One of the coolest sounds in the world, like it's mad that you're making it slow down.
