I need some recommendations or help with my car. I have a 2.5L L4 Manual transmission Stock Altima. I want to make it sound better. It has the stock dual pipe muffler. I hate raspy sound at any rpm and i like deep sound, I was looking at some Magnaflow and Borla mufflers and have a resonator delete but i just dont know what to do. I dont want to spend over $300 because i know that there are some good ones way under that price/budget. Which muffler should i look for one to buy or what are some recommendations i can get from you guys?
