I've been doing a little bit of searching and I've decided I would like to get a Flowmaster Super 44 muffler. However, I don't know what I should do about the Cat. Will it affect the sound? I'd like to have a nice sound and still be able to pass emissions. Also, is it required to weld the new muffler in, or can I just use exhaust clamps? If it has to be welded, I have no issue paying a shop to do it since I don't have welder.

Go with a Thrush Welded muffler. They're built exactly like a flow master but half the price. They sound just like a FM44 as well.

O'Reilly's sells them also.

Yeah, I forgot about the rule. I wasn't planning on removing it at all, I just know that some people DO remove it and wasn't sure if the videos I was watching were with or without cats. I actually had another question that I forgot to type out regarding the cat.. that was which brands you guys recommend? I figure I may as well replace it since I have 177k miles and they're not that expensive...

What's a good weld on LCA skid plate. One that will help with the chance of getting hung up on the mount and to protect it. Those bolt on ones are ridiculous expensive

Bah. So now I have to get a vacuum gauge and test it... someone told me that if I could hear a noise underneath then my cat could be bad?
