Thanks for the data. I 've heard that on many occassions with the C6. The few I have seen with Z06's have had results similar to mine. (But what a feel of a difference, unbelievably disproportional to the graphs is seems). No explanation other than the exhaust ports might need to be opened up with custom head work. Also the 1 3/4" generate more low end torque than the 1 7/8". But I got the later anyway. Kind of makes me wonder why they make 2" ones.

I want to do headers, but can't smell like exhaust when working, which is what I am trying to figure out.

Thanks!
You have probably fried the cat on the side that overheated, and the insides now look like a Weber grill. Replace the cats, and your exhaust aromas will disappear.

I gained 25 HP/TQ w/ my LG Pros, through the stock catback.
