Exhaust headaches

[Nightfever]

Just got my tsudo n1 catback installed. It's not too loud but for some reason it's giving me bad headaches. Even during idle while warming up the car. I don't smell anything, so it can't be the fumes? Could it be something like the frequency the sound is producing?

If it's catback it shouldn't be from fumes since most of them are behind where you sit and you would hear a leak. Doubt it would be a frequency issue.

Yea don't know what it is... even driving it for a couple mins, i get the headaches that would last for many hours. That's messed up.
