Installation was super easy and they fit perfect...took about 45 minutes which included cleaning/polishing my stock pipes and storing them away in the V&H boxes. Sound is perfect for what I was looking for....Very low, throaty rumble without being too loud. I did call V&H and they said no tune was necessary as I was leaving on the catalytic converters. Going for my first ride this morning after it warms a bit and I'll report back with any ECU issues. Simple and painless.... Cost was $799 USD delivered. Model 20065 Twin Slash Duals. TS
Hit the road on a 200 mile trip this weekend....sounds great while not being too loud....no backfire upon deceleration....nothing else to report really....just a better sounding bike and no issues with fitment or ECU. ts
