Looking to make a few engine mods and my builder/dyno man is telling me to get a fullsac header to replace my V&H Power duals. He said that the placement of the cats, right in front of the 2 1 2 makes it real tricky to tune. I like the V&H and really don't want to lay out the $$$ to change to another header just for a couple of HP difference.

Has anyone decatted the power duals? Is it effective, will it make tuning easier and make more power? Or should I just leave it as is?

I have a 103 -w- cams, heads, SERT, header. I'm changing the heads and cams to get more low/mid power.

 

Powe duels are already decatted, there is no cats in the power duels.

 

Your Builder/Tuner is FOS and definitely doesn't know what he's talking about. I'd be looking elsewhere for another Wrench.

 

What he said.

If the builder/tuner doesn't know about mainstream exhaust like the Power Duals I would run.

 

If you listen to your builder/tuner...I have some beach property for sale in central Sahara...

 

Thanks for the responses.

Got it. No cats.

 

 

That was easy.

 

Looking at a 2016 SGS, dealer is talking Fullsac head pipe, I kinda had my mind on a V & H power duel, all opinions welcome! Doing TTS and V & H monster round slip-ons, I don't need every last horse out of it! Wife's mc.

Thanks

 

Either would be fine.
