The problem with many exhaust systems is they can be loud all the time, unlike an intake. Some systems are loud and can drone badly at the rpms where you would normally drive. Unfortunately the only way you're going to find out is install one. Youtube videos are for the most part pretty crappy and don't give an accurate reproduction of how a system might really sound. Look for reviews, read up on real world experiences on various forums etc before you buy. Keep in mind that what a few might see as "cool" most others would see as obnoxiously loud or ricey sounding.:smile2:I tried a Corksport intake and ended up going back to the factory airbox, because the engine only sounded good during aggressive revving. During normal driving, it actually made the car sound like it had a header exhaust leak. I think swapping for better exhaust would be a better, albeit far more expensive, way to improve engine sound.
