I plan on keeping my catalytic converters, so I'll be fine. I was initially concerned because i thought the midpipe contained a cat, but it's a resonator. Any of you guys paired this exhaust with the euro intake? I plan on getting that as well, especially after discovering that there's a charcoal filter in the oem intake. I also heard this makes the exhaust louder?

Here in NJ for state inspection they just plug in the socket to get all info. no old school exhaust monitoring.
I hope it's loud in a good way. Does it sound terrible before it's broken in? What should I expect?
