3 inch cat.
I am finishing my Wrangler LS1/4l60e swap.
I need some informed opinions on the exhaust.
The LS1 has 243 heads, rebuilt with Mahle pistons, 10.5 cr, LS6 cam, Comp Cams 1:85 rockers and BBK intake. I'm guessing about 400-425 flywheel hp.
The headers are Hooker 1 5/8" block huggers into 2 1/2" pipes to a FlowMaster 2:1 3 inch outlet merge to a Magna Flow 3 inch cat into a 3 inch 50 series Delta flow FlowMaster muffler to a 3 inch tail pipe.
My question is will the 3 inch cat kill the flow? It's their 3 inch round high flow cat? I don't have room for dual cats.
Any ideas?

Is the Magnaflow cat you bought one of the spun models? If so, is it a ceramic substrate or metalic substrate?
It might not hurt to call Magnaflow. I have called them before and they were very helpful in giving me details about their products. I tried emailing them and never got a response.
