Why so much weld in BBK LT headers?

cmandockdunk · 03-02-2003

well i just got my new BBK longtubes for my 92LX from Summit! problem is I looked into the exhaust ports and there is a BUNCH of excess weld around the holes. (trust me...there is enough for me to be asking about) Now it seems to me that if we are trying to increase flow, THEN WHY IS THERE SO MUCH EXCESS WELD AROUND THE INSIDE OF THE PRIMARIES??? I dont get it?? SHOULD I GRIND IT DOWN???? thanx for the help!

go ahead and grind it, JBA's and FRPP's dont have this sloppy welding

It wouldnt hurt anything to get rid of the excess . Just dont take out all of it . All headers could use a little deburring . They mass produce them and it would take too much time to do this at a factory . jmho

if you can get a pic of that excess welding that would be great. want to see what your talking about.

spyder- i will try to get you a pic in the next few days. im at college but ill ask my pops to take it.

Like Fordgasm said.....be careful removing to much of the weld. If you overdo it....it will be weak, break and leak.

i got the pics spyder, but im having trouble getting them from yahoo photos, onto this site. anybody know how?

1. Save the pics to your hard drive from Yahoo Pics.
2. Post a reply to this thread and click on the "browse" button at the bottom next to "Attach file". Browse your hard drive where you saved the pics from Yahoo.
3. I think you can only attach 1 photo per reply and max size is right around 1MB. If your pictures are over 1MB then you'll have to use an image editing program to save it to a smaller size.

ok...thanx wagstdy...i think it worked....heres the first pic of the BBK's. you can see some excess, but it is a little worse in places.

wagstdy · 03-04-2003

It didn't work. At least not for me. I think you saved the link to your hard drive and not the actual photo. I'm not sure exactly how Yahoo Pics works but see if you can right click on your picture in Yahoo Pics and select "Save Picture" or "Save Target As".

this work?

cmandockdunk · 03-04-2003

well i think it worked, this is the one that you can see the excess in. like i said, there is a little more excess on the others.

GT Dan · 03-04-2003

Use some common sense here. Before you grind any of the welds....look on both sides of the primary tubing of the header. Look at the thickness of the weld. Obviously if the majority of the weld in on the inside of the tubing then you need to either not grind it down or be very conservative on the amount of material that you remove.

Ideally, the majority of the weld should be on the outside of the tube and the header flange. If its not tolerable then sell them or return them and get something else that is more appealing for you.

Don't grind on them if you think you want to return them.

Yep, that worked.
