I'm looking to get a little more "roar" out of my QX70. I'm not too concerned with the added HP. I've watched a few YouTube videos and they sound amazing. My question is, do I need to do a full cat-back exhaust or is there a "muffler" upgrade that I can do to get the same sound. The cat-back exhaust is a more cut-in dry searching on what you need, but a muffler upgrade isn't so clear. I've read where some have installed a borla muffler, but didn't really go into details.. I didn't want to guess on what I was buying. Any help would be great!
Thanks,
