With a quality exhaust setup you will not have rasp with a catless downpipe.
Why did you replace the stock cat with a maganflow cat, and not just replace the downpipe? The cat on the stock lsj downpipe is a high flow unit. The restrictions are found on the inlet of the downpipe, the dimple for the 02 sensor, and the neck down portion at the end.

be prepaired to fail your MVI with no cat...lol. Unless you plan on swapping them out. We dont have MVI but when i buy my catless midpipes for the truck, im keeping the stock ones incase i move back east and it needs to be swapped out.
