i got one if you want it....not stock tho, I think its 2.25" but not sure nor am i sure who made it. It has been refinished with Eatwood's hi temp exhaust paint and not installed since. If your interested I can get you a pic. I went to the ATR and it cost me $130 and its already rusting I haven't heard anything about postons tho.
Stainless steel rusting . Ive had header wrap [on and off] my ATR up-pipe and never seen rust. Only issue I know about with the piece is that it sometimes is a b**ch to fit.
I have an ATR up pipe & down pipe and no rust.
Stainless pipes will discolor, but, rust - don't
think so. If it does, send it back for that reason.
IMHO.
I just got the ATR up pipe and it was 109 bucks shipped.....comes with a copper gasket too. I am having probs with it fitting to the header tight...........maybe she needs a little red RTV crap!!
My down and up pipe dis-colored within minutes of running the car..........I like the look of stainless steal.....
