Installed a MAP cat back a week ago and since day one the drone has been unbearable. The boomiest drone you've ever heard. Especially at 3500 pm. Acceleration or deceleration, it's insane.
So I contact Adam at MAP for any advice. Good guy. He took the time to admit that I was the fourth FiST owner to call about it. He was honest and told me he had no solid answer for me. Gave me the few tips he could and asked that i call back with my findings. He was genuinely concerned with making it right.
So I was installing a Depo IC and piping yesterday. As I got the car up, I noticed a large puddle of water under the rear most exhaust clamp. Odd. I finished with my IC install and turned my attention to the catback. Pulled the 'S' pipe out and both clamps. The clamp b4 the muffler was soaked! When trying to reinstall that clamp, i noticed it was a bit more snug than the other one. So I looked into the pipe and it was slightly oval!
I put it all back together, extra tight and also holding the piping together while clamping to make sure the pipes touch inside the clamp. Let the car run for a minute or two and sure enough, a fast drip starts out of that same clamp. Dammit I have an exhaust leak on a week old system. Barely 200 miles. This explains the maddening drone.
I'll let you guys know what Adam has to say about this.
