well it is working good so far and yes i would get the petit ast if it was 80 dollars, but so far it looks good and it does the job. i was thinking of welding the extra nipple. right now i have its plugged and it works but i would feel safer with it welded. i compared it to the stock ast and i dont see what the difference is.if i cna figure out how to put my pictures here i will post some of the ast,
