Yeah, the 2063 pipe I like a lot. Never hear of anybody running it in the States. Here it was the matching pipe for the LRP 21X and Nosram 21RR - i.e. Picco P7 Evo 2/3.. Most wicked engine pipe/combo I've seen for all-out power and screaming top-end in a 21.. Works great with the Go too...

Just won my new engine in an ebay auction for a great price - Argus!!
