It got a bit raspier but not much. The HFC's all make a weird noise anyways. You wont be able to tell that much of a differnce. However, the CAI made the exuast muffled a bit. Getting it tunded fixed everything. It all flows nice now
The kit was 10 or so, but there's probably another 5k or so in supporting mods. If I were going to do it again, 15 would be the lowest I'd go on the budget.
