I know this is something that I looked for, for a while, and couldn't find any really solid findings on removing all the stock exhaust components from the 2 primary cats back. I had wanted to get a more gutsy feeling and sound from my 5.0, but hadn't until now been brave enough to just start chopping away. I had already removed the two rear mufflers and replaced them with a side exit setup behind the rear wheels. I love the sound, but it had a slight resonant drone to it. So this week I had the local shop chop off the 3rd cat and resonator and just weld in a Y pipe in their place. Sounds 10 times better! I still need to finish my side exit, but the drone dropped off, and it sounds like a monster when you put your foot to it. I'm going to submit a sound clip for the archives here soon. I want to make sure I use my best microphone on it so it gives an accurate feel. So just for those looking, I've done it, I love it, and for $50, I can't beat it.
