I have a CPI twin stinger muffler non-coated for a Rev 800HO. Bought it last season so it has about 500 miles on it.
Sounds like twin pipes and not as loud as an HPS.
Brought a Dynoport muffler and the CPI muffler to the hill and tested back to back. CPI gained 200rpms over the DP and the DP was equal to stock. Even threw it on the wifes 600 and same outcome, gained 200rpms.
This is at 7,000' so low elevations might differ.
It's the black one.
Can send pictures upon request.
