Box Caprice Dual Exhaust pic request

[EngineandJuice]

Hi I recently went to a muffler shop and got an estimate on true duals for my 88 caprice. $600 w/o cats is what I'm looking at. They explained that they were gonna do the process where you cut the brace for the transmission and go from there. I noticed while searching the forum that many people have true duals by using the LT1 crossmember and all that. If possible can i get some upclose and personal pics of any true dual exhaust on box caprices. Including ones that have had the brace for the transmission cut. I appreciate any help possible on this matter. I can see the price droppin drastically if I can convince them to use some parts I bring from a junkyard.

You can use the LT1 crossmember, but only if you weld an extension to the frame on the driver side, behind the current crossmember mount. The LT1 crossmember is too short to otherwise use.

I'm in the same situation EngineAndJuice. So that's two votes for let's see some pics. You got headers?

I've got an 89 with the single set-up. The cat is hollowed out and I put a Force muffler (generic Flowmaster) on it. I would be happy to find a company that makes a split pipe after the converter to run dual mufflers and tails. Does anybody know of such a part or another vehicle that has that setup so I could interchange the part? I figure some custom exhaust shop could do it but I enjoy doing it myself.

I made my own Y-pipe out of LT1 car exhaust components, and a 45 degree elbow from Autozone. Of course, I have access to a welder, which you will need if you want to do this.

Silicon2, do you have pics? Did you use the tailpipes from a LT1 also? A welder is no problem.

EngineandJuice... I know a guy that would do that for only $275 if you stay anywhere by mississippi...

Another question is what about the floor? Looks like it needs to be banged up to make room for the drivers side hump on the LT1 crossmember. I'm guessing it would need to match the passenger side.

Nope - it will clear it fine. The 'hump' is for a catalytic converter. On the LT1 system, the driver side cat sits farther forward than the passenger cat.

These questions are why pics are so important to me. I'm a visual person so seeing it helps alot more than reading it.

Oh and I'm in MD so that $275 is a no go but thanks anyway.
