STM FP SS housing Downpipe single piece with O2 Dump

Pricey but welll worth it. Fitment was 9/10 only had to remove the small heat shield for AC wires to have the o2 sensor clear. Also lower braces will require spacers. Other then that craftsmanship is awesome. I can see a very slight increase on building boost with the SS housing no logs to really prove this yet. Be sure to have second bung welded on or test pipe with one already. Overall super happy with my purchase, fitment, and quality. Woulndt expect any less from the guys at STM.
