HPI Racing Baja 5B (cpi exhaust)
This is the CPI Racing Tuned Pipe for the HPI Baja 5b and I believe the 5T as well. It fits quite nicely, and is well protected in the event the baja rolls, flips or otherwise tumbles. The CPI Exhaust Pipes performance was great when compared to a silenced and unsilenced JetPro V3 Exhaust Pipe, and the CPI Exhaust Pipe ended up being much quieter in the end.

Overall the CPI Exhaust Pipe is a great addition to an HPI Racing Baja 5b, and easily provides better performance when compared to a Silenced JetPro V3 Exhaust Pipe in my own opinion.
