Options for long tubes with cats

[SethSwitch]

Hello All,
I unfortunately am required to run cats where I live and am trying to find some long tubes with cats. What do y'all recommend?

I run American racing headers and opted to use their catted y section. It's pricy but well built and sound great.

Very happy with my setup and proven gains on the dyno

You're 4WD correct? Did you have any problems with them fitting around the front propshaft?

Not at all. On mine the pass side header is touching a tray for the ac lines. I had to pry the tray a little bit to make some room otherwise I'd get a rattle every now and then.

Did you lose any low end torque after install?

Couldn't tell you. I'm supercharged so I didn't notice any low end loss

Not on a 5.3, but I have Kooks Long tubes and their catted y-pipe. Had a crazy sale on that big website with all kinds of anything auto related things. Can't tell/remember/feel on low end torque loss. Maybe, maybe not. Once she's moving, she scoots. Nothing like sumo though. I kinda want to find a regular 6.2 and drive them side by side to see.
