Hi Warren,
I have a 260B which came with the dual exhaust from piper. The APP exhaust is a similar set up. We fly out West and down in Mexico where it can be hot. I have ridden in a 250 with the stock single exhaust and the heat off the firewall is nearly unbearable. I know there is more clearance between the exhaust and the firewall in the 180 but if heat off the firewall is an issue, the dual exhaust is the cure. My system has been very reliable. Wore the mufflers out after 10-12 yrs, otherwise no problems.Sounds good too.
Good luck, Don
