Won't cause any engine issues, in fact it'll probably make the bike run a bit cooler. Obviously you had no issues going from the stock Mean Streak exhaust to the V&H Big Shots without baffles, unless the issue now is how loud it would be without any baffles at all. Longer pipes have little impact other than very slightly moving the power in the RPM curve. Same for baffles. Removing baffles or adding baffles, aside from changing the sounds, it moves where the power (torque) peak occurs in the RPM range more than anything else.
If your bike has a Power Commander or similar device, it may have to be re-mapped to adjust for the slightly higher back pressure of the pipes with the baffles. I recently installed V&H Super Quiet baffles in the Big Shots mounted on my VN1600 Classic, and all it did was change the power curve slightly.
When life throws you a curve, lean into it!
