Hello. I am installing an RC Components true dual header and slip ons. The instructions say to use the supplied Torca band clamp to install the mufflers. Of course, there is mo supplied Torca band clamps other than one for the lower crossover pipe. Has anyone installed these and if so, did you use the stock Torca band clamps? They seem to fit extremely tight and I put one on with a rubber mallet. Of course its ripping off the finish on the muffler underneath. Thanks for advice.
