Hey guys I'm getting my whole exhaust system done in a few weeks. It's going to be 2.5" all the way through including s-pipe. I was just wondering if anyone has had experiences with any good DEEP sounding universal mufflers. I have been checking out thermal, hks, apexi, rs*r, and magnaflow. I have heard all of these exhausts in person on different cars except the magnaflow. Any help would be greatly appreciated. Thanks.
