Ever since I had coated SW LTs along w/ RT hi-flo cats installed on my 05, I've been hearing a strange noise most every time I shift from 1 to 2 and usually from 2 to 3, depending on how hard I'm on the throttle and how closely I'm listening. The best way to describe the noise is a quick (<0.5 sec) chuffing or snorting type sound that happens when I lift the throttle to hit the clutch and shift. The car seems to be running fine, and this may well be normal, but I wanted to ask anyway.

Thanks!
