Hi Larry ..

The removal of the pre-cat is a relatively easy job - it just requires tenacity and patience! The power gains are worth the effort, so too is the extra meaty muffler noise 🙂

There are plenty of posts on the topic in this section of the forum which should answer most of your questions.

GOod luck!
