Altering header reducer
Maybe it's just the worrier in me, but I thought I'd run this by the experts out there: Because of a slight clearance issue, one of my reducers for my new headers needs a modification. If you see the attached pictures, you'll see how I had to cut the reducer back, and put in a new piece of pipe so the whole thing drops down slightly. It hasn't been welded yet.
My concern is with the new 'lip' inside the reducer (see 2nd pic). I intend to flatten it more against the inside of the reducer for a more aerodynamic fit. But there will still be a lip there. Maybe it's my active imagination, but I'm afraid the resistance of this lip could cause it to get much hotter than it should, considering how close it is to the output of the headers. In my mind I see this as a glowing red hot ring.
Am I being ridiculous? Obviously you want everything to be as smooth as possible for good flow, but my concern is making something that will fail.
