I have a ture Nissan Motorsports competition race header, 1-3/4"OD primaries to two 2-1/2 collectors and the y pipe goes to 3". Wondering what it's worth, it had 2 holes in it, one interference rub hole and one on the bottom where it appears to have drug on the race track. These have been professional weld repaired and gound back smooth. Considering selling as isor getting it ceramic coated and selling.what do these bring ?
I also have a Hooker super comp header it's a 6 into 2 with 3 bolt flange connections on each collector. Its in excellent condition still has 90% of the black paint on it only mild surface rust. What's it worth?
