Rancho Cucamonga, CA | Tom, is your bike a California model? I am curious how much it makes a difference in volume. Maybe we can compare tomorrow. PM me and will get some lunch. |

Rancho Cucamonga, CA | Well took it for a ride up to Hell's Kitchen today just to break in the new pipes and I'm even more impressed! I don't think the Screaming Eagles I had on my Harley sounded this good. Yes, they are louder, but it's only noticable when laying it on. Otherwise it's just a nice deep tone. I think I'll ride Mt. Baldy tomorrow to see how they sound in a tunnel. |

Can The Gatlin Tips Be Used?
I did the cherry bomb mod and use Gatlin Tips. The set up should be the same. Hope that the photos help to clarify the description.
For strength and friction I used threaded galvanized plumbing pipe that fit into the extensions off of the back of the muffler. Use a Dremel type tool to grind out a little material from the back of the Gatlins to permit the pipe to recess into it about 1/2 ". Use stainless bolts nuts and lock washers (sorry I don't remember the sizes). Run the center of the three mounting bolts up to the pipe and tighten enough to mark where it makes contact - drill a hole to allow the bolt to pass through - (the pipe is heavy enough that you could probably use a smaller drill bit and tap it). As you screw the bolt in thread on a nut and then put on a lock washer before it goes into the pipe. When it goes into the pipe place another lock washer and nut on it. You will want this second nut to start as soon as it can as there isn't much room to tighten it from inside the pipe - finish screwing it in and tighten both nuts towards each other to lock it on. The other two bolts will be shorter so that they just tighten up against the outside of the pipe - use a lock washer on each of these.
One issue I need to go back and take care of is sealing up the back of the tips around the pipe. At the right angle you can see the mounting set up through them. This should have been done before I mounted the tips, but live and learn.
Anyway it can be done. Excuse the ugly photos as I was out riding in some snowy slush this morning.

Corona, CA | <<Tom, is your bike a California model?>>
No it is not. I bought it from a guy in Michigan.
I wish I has seen your posts earlier, I would have liked to meet up with you. I was busy Friday with a Patriot Guard mission from Garden Grove to Riverside Cemetery.
I took a long ride yesterday and just had fun playing with my Go Pro camera.
I sent you a PM - give me a call and we'll compare notes on the stuff we've done. I work from home so anytime is good for me. |

| I would say it is, as most of your heat and air volume exits the right pipe. |

| They are in the crossover also, They are honeycomb diffusers that help your mid range HP and torque don't mess with them. They also allow heat to be maintained in the head pipe long enough to avoid tweeking a valve. They are not cats, that would be an additional component mounted externally. |

| I bought my Cross Roads with a Stage 1 set up and like it enough. I don't love it but I like it. Following this thread I decided to take a plunge and attempt to do the thrush mod on my XR. The issue I'm running into is the glass pack is too close for my liking to the saddle bags. On the stock exhaust and the stage 1 exhaust the exhaust drops approximately 1.5 inches from the head pipe then back. The stock pipe has an odd hickey to it. A buddy of mine and I have a couple of idea on resolving this but I'd like to keep this in the spirit of the original mod. Cheap, easy, and off the shelf if possible.
I've attached links to my pics. I'll post them once I figure out how to do that on this forum.

Rancho Cucamonga, CA | I went from S1L1 to thrush without any remap nor any popping. I still have a heat issue, don't know if a remap would do anything for that though. |

| I've pretty much figured out everything to get this thrush mod done on a Cross bike. It's not as simple due to the stock exhaust design. Still though I'm keeping this as an off the shelf mod as possible. Some fabricating or competent exhaust shop work will be required I'm afraid. I'll post on the Cross bike forum here later with a complete how to. Thanks to the originators of this mod! Your experimentation inspired me! |

What is it with these clowns in a cage? Had a guy do that to me the other day with nobody in site behind me and then go one block and hang a right.

| I finished the glass pack install on my Crossroads. Consider yourselves lucky to have a direct fit/bolt on mod. It took a bit of fabrication to get the glass pack to fit but it's well worth it.

DeRidder, LA | Installed glasspacks today, love the sound. Fabbing some brackets on Thursday and tacking the tips to make it rock solid. Got a compliment on the sound on my test ride. What to change now?????? Still need to finish my brushed aliminum to carbon fiber vinyl transformation. |

| Love the exhaust mod! I have a question for you. Your signature talks about a custom passenger backrest. What is that about. I have been looking for something for when I take my trunk off but haven't been able to come up with anything yet. |

| I have a Stage 2 exhaust that is on the Vision I just bought. Can I still do the Thrush mod with these style of pipes? I havent picked up the bike yet and dont know if the chrome heat shields are like the stock ones or not. Really want to do this mod when I get the bike. Hope I am not disappointed!
Thanks
