Engine/Transmission (1998.5 - 2002) pre-tapped ports triple piece exhaust manifold

Not sure if I got BD, ATS or other. But kinda sure there the same. Any way mine has two. Are they both 1/4 or is one 1/8? Its hard to tell right now cuz the manifold is upside down with the twin set up. And it's real HOT!

ats uses a real small hole, 1/8 i think. I had to drill+tap mine for the larger ISSPRO probe. I dont think too many guage manufacturers use a probe that would fit in ATS's manifold.

My autometer probe fit in my ats manifold w/ no problems. They use a smaller probe, but include two different pieces to use either size hole.

Thanks for da replys. One port has my gauge thermocouple. I'm installing a K type probe for my water methanol set up. Hope I could use a reducing fitting at the other port that will work 1/4 to 1/8. to make things easy. I tried tapping into my gauge but it did'nt work. They say if I have a amplifier to install it prior to it. Not sure if tied together readings will be off. Temp is VERY important I run 5x5 and tow all the time.

I found that BD is ATS. I ordered up my 3 pc manifold from Diesel Parts Direct in Cedar City, UT a couple of days ago. $399 plus $38 for gaskets, free shipping.

Some porting and polishing is now in order I understand from what I read.....

What a difference the manifold makes. It makes the turbo spool up a lot faster. And the egts are supposed to be lower.

I notice no difference in spool up or EGT's, but I don't worry about ripping the ears off my head!
