But worst of all it'd choke the engine. It would totally negate having done any work on the exhaust at all and even with headers you would probably have a worse performing exhaust setup than stock.
2 Cats, one per banj is the way to go. Cammed/bolt on LS1's are fine with Mahanflow Carsound £2 core CATS.
More extreme setups would want Metal Matrix 3" core setups from Random Technology or Magnaflow.
If you're in CA it's a different story however, as LT's aren't legal.

Standard UK layout QWERTY keyboard
This is totally user Error! I meant 3" which is the nummber 3 key and shift number 2 key for the " inch symbol. However I must have held shift down when I pressed the number 3 key which gave me the pounds Sterling £ symbol.

I didn't know if you went and found that on a character map or if it was indeed on your keyboard. Cool fact.
