New Header on the market, Top-End Performance

Top End Performance has been around for a good amount of years. I know they make some pretty nice stuff for BMW's, although the older models 2002, 320i, e30's. I stumbled onto these headers this morning. The price is right. Build quality looks pretty good, they just need to be coated or painted.

Just because it says it's for a E46M3, does not mean that it will fit on the Z4M.
More investigation is required.

Ya that is a very time consuming/expensive gamble. I guess somebody has to bite the bullet and should do it

they look like shit anyway..... the CSL units make these look exactly what they are.... very poor quality, look at the welds on the engine connection piece, the way the tubes merge into the collector looks so poor im sure that wil cause a restriction... please jesus, pplleeaassee dont put these on your s54.

O2 sensors in the wrong place, odd placement on the egt as well.

Did anyone look any further into these headers?
...painting them black would make them look a lot better.

IDK if it's just me, but these look very familiar; like something else that's been posted here.
.....I think its the way the flanges look.

Just checked with the seller.
These headers are 14g mild steel.
