Default New side pipes

I just removed my stock BDR side pipes and replaced with Cobra Paks. Rejetted up two sizes and now we're off to the Dyno. Sounds much better, this motor has to be breating better, the stock pipes are really restrictive. I'll post the results.
Before:
KC-408w, motor dyno'd 554hp/552tq
RWHP: 419.7/430tq
BDR #621
