Would you know, is the end of the pipe being exposed to exhaust <br>
gas a concern with the Bolly pipes & mufflers?<br>

The bigger problem is that if the pipe is composite (CF) you will <br>
ablate the pipe input and ruin the pipe. I've seen 3 of these for <br>
repair. The hot exhaust gasses can not be allowed to contact the end <br>
of the fibers and resin for most resins. ES pipes fail in this <br>
fashion. Some people have been successful in using a squishy coupler <br>
(like the Macs grey) but this is not a reliable setup for most people. <br>
