Need exhaust help

-re post4, the GV; I thought,years ago when I bought it,That it was the cats meow. I really liked that I could put it behind, this that and the other thing. It works great.Its especially nice behind the 3.09-O/D box. 7 useable gears,almost perfect splits.PITA around town. That unit shifts extremly fast, and takes abuse. Rips spring-hubs out of stock 340 discs with CenterForce pp.Shifts nice if you clutch it like it was a regular gear change.
-What I dont like is that GV wont sell me the tools to rebuild it, nor will they sell me adapters for other trannys. They want my current adapter back.
-In hindsight, a shoulda saved up for a 5 speed. Or, possibly,a Winters rear.
