I was basically just wondering of the pros and cons. Pros: sound, cheap. Cons: (likely) a tad bit of power loss due to less muffler related backpressure, possible CEL's. Anything else? Never really looked into it much. Figured I'd ask.
As long as you still have the resonator. While I love how my car sounds with the SPT Exhaust we installed in February, cabin noise has been a bit of an issue. I may be revisiting my exhaust system to re-install the resonator that was subsequently removed when we installed this system. The growl from the 2.0i Boxer Engine is beautiful, but the noise inside my 5-Door gets a bit unbearable sometimes when the RPMs are just between 1k and 2k as well as between 3k and 4k. At first I thought Dynamat or some kind of soundproofing would help, but yesterday I was told "Oh yeah hey, you don't have a resonator."
