We wrapped both our 2007 Bulldogs with V&H Big Radius II pipes (full heat shields) because the rear cylinder pipe heat shield is very close to the side cover by 3/8". We wrapped the rear pipe about 5" down then replaced the heat shield over the top. Fiver years now and no difference can be seen between the front and rear head exhaust ports when the pipes are off. No more blistering of the side cover paint either.
