Okay I have a diablo sport,with the exhaust flowing threw the Magnaflow,iam seeing 28.4 of timing O Kr. Threw the cutout I was getting KR,so i pulled timing and got the my 28.4 O Kr Okay.


Which would make more power threw the muffler or cutout?
I know this sounds funny,on the muffler question. I heard people
the cutout really doesnt make a difference compared to the magnaflow. But i have a ORy-pipe,and heard other people say with you have no cats that's when the cutout comes in <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

cats = restriction
if your running ORP, i wouldnt get a cutout.
themagna flows pretty good, keep it the way it is.

I have a cutout,so which way should i go cutout or muffler? This a Race setup only. The magnflow takes out about 1-2 hp maybe more who knows. I have to get a dyno done. Ever little bit helps right?

I'll say this three times so that I'm clear about it...

NO muffler outflows a cuttout.
NO muffler outflows a cuttout.
NO muffler outflows a cuttout.

If this is for race, use a cuttout or open headers with 20" extensions. In racing mufflers are good for three things. Meeting class rules, adding weight to the car, slowing you down.

I just wanted a second thought.
