Roadchaser, our slip-ons arent the loudest ones available, but they will give you one of the deepest tones possible. We use a triple-stepped perforated core on all 5 styles we offer in order to maximize your bikes low-end power.

 

Cheesehead, I would guess it would void their warranty because I drilled out the baffle rivet from the bottom to 3/8" to install the TTI's. I bought my bike used, so I am the second owner(no warranty) and the way these are built, I don't expect them to have a failure.

 

So, am I getting this correct. If you just ****** the mufflers off and add slip ons, do you need to change your tune or not. I am seeing both ways. I do plan on a power commander and tweaking everything at some point, but sure would love to just slide the new pipes on and run for a bit before go all out. Mine will have the factory cats (in the begining anyway) but will change to strait headder or cut the cat out at some point. And I guess then I would need to be ready to tune it, but for just the slip on pipes, will I hurt anything running for a bit?

 

You can run the mufflers without the tuner for now...
