Just finished installing my Kooks Mids (1 7/8). Install went pretty smooth and other than the one plug boot hitting the header all is well EXCEPT...upon startup it sounds pretty much the same, maybe a tad bit loader but when I put it in reverse there's a big change in the sound--it goes much deeper....I have no idea why.
This isn't driving just idling with my foot on the brake. In Drive its fine sounds normal, in reverse sounds weird. No big change in RPM...
I'm stumped.
