Threw out the cat

[Tulefog]

I jacked up the Spyder, put the jack stands in place, and removed and replaced the catalytic convertor with the bypass from Pitbull. I did find that the clamp on the right header and the catalytic convertor was very loose, but the slipjoint did not show any deterioration. Probably with only 5,000 miles on it, too soon for hot exhaust to cut through it. That could be part of the heat some have noticed, though i don't think it was for me. The clamp on the muffler to the catalytic convertor has RED Threadlocker on the two bolts, i was working on my first hernia of the day, when I realized that, got my plumbing torch and carefully heated up the threads on the two bolts and they came apart quite easily. Autozone has a tool loan program, i put down a deposit and got a large pipe expander and stretched out the two bypass joints to the headers, put the slipjoints on the end of the headers with a little lithium grease and it went together very well. The spring on the right side is pretty tough to remove and replace without the headlight spring tool. i did it with a pliers and large screwdriver, but it was ugly, that spring has a lot of momentum if it gets away and can hide almost anywhere. I had a senior moment and installed the bypass, then remembered to wrap it with Thermo Tec tape and held that in place with stainless radiator clamps. That does help hold in the heat. I put the stock muffler back on and after putting everything on loose, aligned for a snug fit and tightened it all up.
All good, i took it off the jack stands started it up and let it run for five minutes. Then i shut it off took out the key and put things away while it thought about the change and adjusted itself, then started it up and tried it out. it did add more power and it seems to run a little cooler, not much louder but a lower tone, at 100 outside its hard to tell if it will make the ride much cooler.
The tips and advice that have been posted were really important because the bypass does not come with instructions, thank you for all those who took the time to post their experience and guidance.
Also i am lucky enough to have friends who have done similar projects on Harleys.

Thanks for the heads up

How does it sound; man?
Tell us about the sound! :2thumbs:
(Or even better; post a video of it!!)

If you are really going to throw it away, I have been looking for one.

Exhaust sounds with cat bypass

I put a short video on YouTube for the new revised exhaust system with the cat bypass. Kinda likes to clear its throat a little, just as long as it doesn't spit on the sidewalk. The address is:

With the advice of counsel, I will keep the catalytic convertor just in case I have to make it more legal.

I never understood what those springs were for. My bike did not have one from the factory. Louise bike did but the SpyderAttitude cat bypass was so poorly made that the spring clip did not come close to lining up with the header clip so putting the spring back on was not going to happen. So neither of our bikes has the spring. Both of the clamps are tight and have seen no movement or leaks. Is it just there in case the joint comes loose to keep the pipe on the bike?

Congrats on successful cat-ectomy.
