I am going to be installing my pacesetters with the ORY this week and I really want to keep the stock muffler the SS comes with. Will I be holding that much power back by keeping it like that? What can I expect it to sound like with no cats and stock muffler?

 

Sounds like a good set-up, no pun intended. Stock mufflers are the best for keeping interior resonance down.

 

Thanks Soquel. Do you still have the stock muffler with the cam in there?

 

Keep us posted on the results of this. I thought about doing that same thing to the hd.

 

I really want to hear a clip when you get it done I think it should sound pritty good, I would just spend 30 bucks and put a cutout on for the track

 

No, but I have a really big magnaflow, almost as quiet as stock. I put in a cut-out before it. I'm running it open right now but If I go on any long trips or get tired of the noise I just cap it up, still pulls great up top

 

I will definately get some sound clips when it is all done. I am gonna wait for the tune though(end of the week or early next week) cause I am deleting the cats and I really dont want my truck throwing any crazy codes with 1300 miles.

I heard you shouldn't run these trucks open headers, any imput?
