Can't say for noise as mine hasn't left the driveway in a month...Hey guys, bringing this thread back for a minute. I know for some of you it's illegal to remove the cat where you're from, here we do not have emissions testing or anything like that.
Question is if I were to get an exhaust shop to remove the cat section, will I get an engine light? I run a straight pipe on my BRZ and when I removed the cat I had to change the tune to remove the light.
Also, how much louder will the Legnum get roughly? Will it sound okay, or really drone?
