Default MAC/ORY to LT?

I currently have MAC mids and an ORY on my car. I'm thinking about swapping over to long tubes, not sure if the ORY will fit LT's though. I've searched and found that people show minimal gain, but I'd like get them to help support later mods....what do you guys think?

Thanks!

I am thinking of doing the same thing. Just not sure if it worth the trouble.

Yea I'm in the same boat....$400 for coated headers, plus I'm not sure if I need a different Y-pipe, or could modify the one I have now....all for a few hp?

from what I understand the Mac Ypipe will not work with the LTs. I reason i want to get LTs is because it will produce better low end torque. I don't really think there is much to gain on the top. I think my cam would work better with an LT. Oh, and most of the Ypipes for Lts are 3 inch and ours are a 2 1/2

You could probably hack up the MAC Y-pipe to make it fit since it is initially longer, but it wouldn't be worth the hassle.
I went from MACs to LTs, but have nothing bad to say about the MAC headers. For a bolt-on car, they are a great set-up...

I went from macs to lt's, the improvement in sound alone was worth the swap IMO. Nothing wrong with the macs, but with the low prices of lt's nowadays the macs aren't the bang-for-the-buck they used to be.

I felt a noticeable SOTP gain throughout the entire rpm band after switching to Pacesetters/duals from macs/ory/cutout......and that's with a recently calibrated butt-dyno.
