ATR headers or TR customparts headers

[bilt2run]

Just purchased another Buick. To my pleasant surprise it has a mint set of ATR headers installed. I have a brand new set of Mark's headers Whatca think?

Why remove them to put another set on? Just more work for no gain.
Mark's look like a copy of ATRs anyway. Sell em and buy something else

sell the china copies (marks) and keep your ATR ones just for $ value

but to be honest the china stuff works just fine with some tweaking.

 

[TR Custom Parts]

Why take the ATR's off??? No sense if they are still in good shape. Buy another TR to use the headers I sell.

I thought that Mark's were improved (flow wise) at the crossover merge to the pass. header.
