hello, I currently installed a n1 2.5 muffler, but wish to have something louder. I have a 2000 Hyundai Elantra. Does anyone have any ideas or know of any cat back systems that would be appropriate for making my car type and year sound very loud. I do not wish to take out the cat converter and straight pipe it. Im looking for something somewhat deep andthroatyy, kind of like when I had my flex pipe leaking in the exhaust. Please help me so I can spend my money correctly.
