Hello, greetings from New Zealand. Just bought a Street Rod with the V&H Hi-Flow Muffler. I love the sound but after riding for a while it is getting too noisy. Did you install the V&H quiet baffle ?? Did it make a big difference. Thank you.Hi all. Just put a high output silencer on my rod. Now have the check engine light up! Didn't expect this with it being just an end can. Is this normal? Thanks. Bren.
