I just installed a Solo mach shorty unbalanced cat back system and it sounds good but just isn't as loud as I had expected. I realized videos make them sound louder after taking a video of mine. Not knocking solo or the kit what so ever! Just wondering what my options are for adding a little more rumble to it? I will be doing headers and hfc's & tune shortly down the road but until then can I replace the shorty muffler with an x pipe and make it louder?
