Glad to see it is working well. Looks like a good piece. Is the pipe size a little bigger on the jegs pipe, or are they the same?

It's 2.5 inch, which is the same as stock but it doesn't have the squashed area in the cross over that the stock pipe has and it is mandrel bent.

What is the part number on the Jegs-Y pipe and how much does it run?

Thanks

Nope, it's on my truck right know. Well, i guess the only issue is you can't put the pass side rear O2 sensor in, but I didn't use either of the rear O2's (see the second pic)

Maybe that's what they are talking about but I don't even see why it even comes with rear O2 bungs. Rear O2's are worthless without cats
