Catless y pipe hunt & Solution
Hi everyone,
I've searched all over the net and can't find a new y pipe for a 98 b4000. Just catted versions. Anyone know where to get one? Below is rough write up of what I have done to get my truck on the road again. It was a pain but in the end, everything was doable.
I've decided to buy a pacesetter kit for 97 ranger. It's 1/4 price of the jba kit, but also I'm guessing 1/4 the quality too, although I have no JBA kit to compare.. Here's what it's looking like I need to do/modify so far...
The driver/left side manifolds cylinder 4 pipe drops down too low by almost 1/4" and hits the coil over shock frame build out. So I could have taken a lot more time and cut a section out and re-angled it to avoid the mount but I decided for this time around I'd just pound a flat spot where needed. It worked and it mates well now
Passenger side fits perfect but it's really close to the transmission coolant lines but they bend away pretty easily *insert manifold to y pipe bolts before bolting up passenger manifold*
Y pipe fits good *must take time fitting with converter in place. Adjust 97 converter hanger rod first*
As for the converter, I was thinking about modifying the 97 y flange to accept the 98 cat flange by elongating two of the three holes and confirmed with gasket templates it would work great! But, I noticed eastern exhaust made their 97 cat pipes with the same universal converters as the 98 b4000 so I decided to buy one. The 97 converter fits well, just the hanger rod needs slight modification. Both the length and angle needs adjustment. I cut about 2-3 inches off the rod that inserts into the rubber mount.
I also bought a 97 intermediate pipe for the flange to mate to the new 97 converter as mine was welded to the original 98 converter. But I think a regular 2" flared 2 hole flange pipe would work.
The 98 egr tube from exhaust manifold also needed some custom bends but I think a 97 egr tube would have fit perfectly.
And finally, the oil dipstick tube needs custom bends to fit right due to the continuous metal piece joining the exhaust ears. Probably would have been easier to just cut it out instead of bending around it.
