Looking to upgrade from the factory Callaway. Seen the pope engineering has one but its out of stock on the su website, was wondering if there's better bolt on alternative or if anybody has experimented with SR turbo downpipes..?

2003.5 cluster, 145/146K(?) miles on it. Includes a few bulbs. 100% working unit. 150$ from SoCal 92118. (CONUS only) pics of actual offered item. I used this in my P5 - for about a week. Car is sold, I don't need this anymore.
