Lossa Brand Big Mouth Scram Muffler

$ 170.00

Lossa brand Big Mouth Muffler. Large visual outlet diameter but maintaining the internal core diameter that matches the inlet diameter for 'tight' sound. Brushed stainless WITH WELDS SEAMS REMOVED! 13" overall length including inlet slip section. Big Mouth Scram muffler, 13″ long, come in 1 1/2″ inlet (Fits on Stock New Triumph header pipes), and now available in 1 3/4″ and 2″.  Because of the larger internal volume of the cylinder, they tend to have a deeper sound than our 12" reverse cone mufflers.  These are universal, so you will have to secure and support them properly. If you are not going to weld them on and are going to use a clamp to secure them, putting slits in the end will help hold them on(we can do this for you before we ship them, just let us know).  Contact us for customizing these before we ship them to you.

*Price is for One Muffler!

 Note: Our measurements are inside diameter (ID), so if you have a 1 1/2" outside diameter (OD) that you are attaching to, order our 1 1/2" muffler.


Measure your exhaust pipe correctly where you want to attach our brand muffler, we are not responsible for you ordering the wrong size!

Now available in a high temp ceramic black powder coating!  If you choose this option, please allow an additional 7-10 days before your mufflers will ship.
