Hey I work with Byrne Heninger, and the wrap around heat shield we provide can be installed without the removal of the muffler. The wrap around design not only protects the frame from the CAT but also reduces the amount of direct heat that can rise up to the drivers side exhaust manifold. The heat shield is made up of a asbestos-free material that can withstand the heat put out by the CAT without the danger of handling the asbestos. The price for the wrap around heat shield is $90.00 please email me directly if anyone is interested or has any questions. thanks Sean Mullins seanmm@xxxx
