Cats for the LS

For all you that have swapped in an LS what are some of the better cats to use. Need to start looking for some. Plus what have you all used for a muffler and where did you locate it.

I'm going to try the Vibrant GESi 7525 metal core. I blew out one of the inexpensive ceramic universals...

Nice but man they are pricey! I need to stay on the budget minded side from here on out.

Motor is on the way and I need to find a 6l80e, then start getting the little things, cats, muffler, tubing manifolds and etc.

Cheap cats can last as little as a year and 10K miles. If you need them to pass emissions, I would suggest investing in some high quality ones.

If you just need them to for the O2 sensors and such, well, cheap ones might be ok. Might.

Magnaflow 49 State Converter 59956

Not as good as a factory converter but they seem to work well every time we used them. The price is right and they fit really well in a custom applications.
