Wife had her 2011 TriGlide set up with SE Stage l, SE tuner, Tr-Dul head pipes and Street Cannons. It sounds great but is much louder than she was expecting. We've been told that without the cat, the pipes will be much louder than normal. What can be done with the head pipes to make it sound like it's suppose to? Is there a head pipe available that will work like the original but without the cat?

 

Yes it will be louder without the cat, but the true duals are not doing you any favor. They do make it louder and kill some of the bottom end torque. If you're looking for a good head pipe replacement that works like the original without the cat, the Fullsac Sportpipe is nice economical replacement http://fullsac.com/product/fullsac-sportpipe/.

 

You can try some Thunder Torque Inserts from DK Customs they come in three different sizes.
Cost $18.95 plus $8.80 or so for shipping, they might be just what your Wife needs for her Tri Glide.

There are many people out there making cat-less header pipes, and they make any muffler louder stock or not.

 

Crusher mellow.
