QTP stainless cutout? i got one and noticed that there is a lip of metal where the two pieces are welded inside. should I grind/smooth this down? i know this would increase flow with the cutout open but it will probably be less efficient closed b/c gases will get trapped there. Is that lip there for a reason? should I leave it be?

That lips there because its a sloppy job. My flowtech cutout that I butchered was horrible.
You can fix it, but it's not going to gain you anything. When the cutout is open, you have to remember that you've now got two 3" paths for the exhaust. It's not like it's all trying to flow out of the cutout.
Think of it more as a pressure relief than an exhaust diverter....

You need a lip for the othe pipe to weld to. You do not want the weld to crack
Also the cut in the staright pipe is on a angle which make it large than a 3" diameter hole.

Mind your business. And for your info we make them in house, so quick talking smack.

I definitely understand why there is a lip now, I love QTP products(just got your headers), I just wanted to know if taking that lip down by using a dremel would gain a little more power(minimal). My belief is yes. Thanks QTP for awesome products.
