Yeah, I still had the stock muffler on after the cat was deleted and it got a little louder but not bad. Later on I had the Flowmaster 70 series muffler added with duals to the rear bumper and that sounded a lot better. Now all I have to do is get the Flowmaster Y pipe I bought off of ebay installed. I hope that helps it to breath better. We'll see!
Later...
