Dual exhaust options for my 87 454?
I've got an 87 454 1 ton 4x4 GMC that's currently got what looks like a home-made, fully welded dual exhaust with no cats. The exhaust is dieing a very quick death, so by next fall I want to replace it. I'd like to run a dual exhaust just like I have now, except that I need to try and find a place to put cats in so that I can be all nice and legal. The thing is, it's very tight up there with the exhaust running next to the transmission and transfer case above the crossmember. I don't really know if I can accomplish what I want, or if I'm going to have to try and find a y-pipe and go back to a stock type configuration.
Anybody have any info/suggestions?
