Well, as I posted a while back I turned the dial to 11 with a miss shift. I've noticed my exhaust sounds different. I haven't any any time to really look at it until today. It's not leaking anywhere. I know it's defiantly a bit louder and it barks a bit more when power braking. What I really notice is that my low end torque has dropped. I have the same feeling I had when I had a hole in my exhaust and lost a bit of back pressure. I think I may have toasted the inside of my cat. The Borla is straight through so there is nothing to get stuck in there. I haven't had the time to take the exhaust off and check the cat. I probably won't until the summer and even then I might forget.
Anyone want to take a guess?
