Default Speed Engineering True Duals with 93-97 Headers?

So, in my infinite wisdom I have made the mistake of trying to install my SE exhaust on 93-97 headers, instead of the 96-97 headers that resemble the LS style headers. I was wondering if anyone with any experience trying to make an LS1 true dual system work on an LT1 could share what they did. Thank you!

I'll be running the XS Power headers (Kooks clones) with the Speed Engineering true duals and my plan is to use part of the y-pipe that came with the headers to mate up with the true duals.

XS power headers mate perfectly to the SE true dual kit. That's what I'm running.

Thanks for that info Elky SS are there any clearance issues (steering shaft or ground) with the XS Power headers or the Speed Engineering true duals, what about under hood heat?

Do you have any pics of the setup installed on your car, thanks?

I just ordered my Speed Engineering true duals and I can't wait for them to arrive, Elky SS could you post some sound clips of your exhaust as I've only ever heard them on LS powered cars?

Speed Engineering true duals just arrived, I can't wait to get the rest of my parts (tubular K-frame and lower A-arms, Faceplated T56 trans checked/assembeled) so I can put everything in the car. Here's a pic of the new engine.
