Default ls7 441 catalytic converters?
Unfortunately here in New York we have to run cats and are not sure what to go with?
We really don't want to spend much over $200 for the pair.
After a lot of research we realize how expensive they can get!
Our biggest concern is, we want to lose as little power as possible!!
We at least for the time being Will have them mated to the Tsp 3" true duals.
Any suggestions?? Thanks!

3" thunderbolt cats are 50 bux each. Magnaflows are 75.

Take your pick.

Whichever cats we end up getting now may end up being temporary. Just don't want to not be to get the car on the road this year because of it.
Yet want to lose as little power as possible.

Its been hard looking into this... have read articles that claim their really isn't much HP difference between brands and some say otherwise?

Was looking into those. I think they are called GESI. All of the prices I found were over $500 per cat!

Haha, very true! We have a friend that does inspections but he insists on cats. Seems to be the big thing that you can't get away with in New York State.
