Im ordering the magna flow 4" turbo back system with cat delete and high flow muffler

Questions:

Why do alot of you delete Muffler not Cat ?

Should i Delete the Cat and Keep the high flow Muf or should i just do straight 4" pipe turbo back ?

Just looking for the different options and Best

You ordered the setup I have, sounds great! I'm not sure why some would leave the cat and remove the muffler unless they think straight pipes would be too loud and the converter would take the edge off. I can't believe it's a weight issue seeing our rides are tanks already......

Will this void my warrenty ? And should i keep the MUFF

For the most part removing the cat on an 6.0 will void your warrenty if repairs are needed. It is also an emissions violation.
