Distance Behind X Pipe?
- Thread starter busterrm
- Start date
if you weld the two collectors directly to the x-pipe between them,
its SURE to cause fitting and assembly and alignment issues
Yes, like Grumpy said, you don’t want this to be welded solid. When I am in the construction stage there will be a V band connector in the middle of each 2 1/2 pipe between the collectors and the X pipe. Also, when you weld something that is round it is better to weld it in 1/4 or 90 degree segments. Weld one segment move 180 degrees from your starting point, weld 90 degrees, then go back to your starting point and weld that 90 the opposite direction, then go back to the starting point of your second weld and finish the joint. There will be some drawing from the welding but if you do it this way it draw evenly and easier to work with once it cools.

Oh crap, I forgot one of the v band connections will be in the middle of the 2 1/2 pipe before the X pipe. Then another just before the mufflers.
I will weld the 2 1/2 pipe the collector let it cool in place. Then put in the V bands, let it cool, cut the pipe and weld in the X pipe. If I put it all together the welding heat will draw it all out of shape. So I will do it in stages, let it cool in between, that will allow me to do the fitting with cool parts for better fitment in each stage. I sometimes say it like it all magically fits together, and forget some of the guys reading this are not fabrication specialist like myself. So sorry! Once I am doing it, I will take pics in stages and list precautions to do a good quality job!

it won,t make a difference you could see anywhere else than on a really accurate dyno graph,
but in theory its the distance too the collector block off plates at the 25" mark on your diagram,
keep in mind once the exhaust system is attached in completely changes the exhaust scavenging efficiency
and reduces the scavenging effect properly made open headers would have

yes you can get the socket head stainless cap screws in various lengths threads ,
and at cheaper prices especially if your willing to drill the wire holes yourself

yeah it helps to own a decent drill press and mill vise
buy some size #56 cobalt drill bits to drill holes for safety wire in header bolts
your local hardware store won,t have them this cheap, buy the 12 pack, they are small and easy to break if you don,t use them correctly and drill slowly while spraying coolant oil

These are the header bolts I was thinking about using when the headers and exhaust is finished.Those bolts have a set screw that goes through the center of the bolt and spreads the very end of the bolt locking it into the threads and hopefully will prevent them from backing out and causing a header exhaust leak.
