Hey guys so I've been thinking about trying to get my car to backfire whenever I downshift through the tapshifts. I have nothing engine wise modded. Only thing I have done exhaust wise is mufflers removed and I believe my resonators are removed as well! I want like loud pops and a couple of my friends told me to remove my cats and it will pop like crazy! Is this true or what do you guys recommend?
