What was it about the stock system that you didn't like?

Are you sure the valves aren’t always open? I had this problem once. Valves were always open and the loud sound was skull shattering.

Hi John,
I spoke to Michael at Cargraphic regarding this and he said they no longer make this set up due to O2 extension cable requirement. You're saying they still offer this?

I think I will either go back to OEM, in which case I will have a set of Soul OPF with jet hot coating for sale ... or I *might* try the Akrapovic OPFs...

I think you'd be better off installing the stock OPFs and if that is too quiet with the Akra rear then look at other OPF replacement options, such as those from Cargraphic.

Akra OPF pipes won't sound any different than Soul. They are both the same thing from a performance and sound standpoint -just basic piping. Only Cargraphic with their resonated pipes might make a difference.

According to Michael from Cargraphic, it's the OPF with flow optimized inserts without monitoring for ROW models. This will make the sound more subdued and gives you no drone and no raspiness (resonance) when mated with an X-pipe silencer.

Eric @SupremePower is working on it for me! ( )

I'll report back on the combo of this and the Slip on... which might be the ideal solution for me! (vs going back to OEM)
