      Muffler adapters

      The curvature is perfect. However, I'm looking for a 1.5" slip fitting to connect headers to adapter. The pipes are a great buy, but the slip fit small concentric adapters are a bit of a hassle.

      Perfect for the job!

      Needed to extend my headers on my KZ440 and give my new mufflers a slight up and out angle. These were prefect. Excellent fit.

      Nicely made didn't work for me.

      These are very well made but I did not like the way they make the pipes flare out on my 2011 triumph so ended up cutting them apart to make my own adapters.
