Thank you - it looks like they stepped-down the after-cat portion of your downpipe correctly. I have the aFe non-catted part and am holding off putting it on the car because they did the step-down backwards before the bend (small bottom piece in the larger top piece) creating a ridge inside of the downpipe. Just trying to see how common this is with aftermarket exhaust components being made for our vehicles. They've offered a refund on the part, but won't offer a replacement with this step-down corrected because they don't produce the non-catted version of it anymore. Considering my options.
