Installed my down pipe today and deleted the cat from the oxygen sensor back. I plan too match the down pipe to the original flat black of the headers to give it bike a cleaner look. Install took a couple of hours with a support bracket also installed to provide added support to the down pipe total plus labor $100. Now my R3 sounds like a true GP bike which is awesome but the sound from the pipe is louder but not annoying at all. The slip on was louder by itself but still on the quite side. With out the cat my R3 has lost another 5 pounds and its noticable it all the right areas. The bike is in need of a full air fuel mapping but as it stands right now the bike is running a little on the rich side with a slight pop coming from the pipe under hard acceleration and down shifting but its not a bubbling popping or anything to worry about. Over all Im happy with my results will dyno tune soon and I saved over $200 over a full system which in my opinion isnt really worth it. Here is one picture I will post more photos soon.

Where do you plan to get it tuned? What type of fuel controller do you have in mind? My full exhaust comes in tomorrow.

If you block off the AIS system it will pop less on decelleration. Of course, this defeats even more of your emmissions system. On Hondas this is called the PAIR valve. Sometimes you can make or buy blockoff plates or you can just cap the line. If you cap the line you want to make sure moisture doesn't build up in that area.

I plan to get my bike tuned at [email protected] motor sports I have a friend that is contracted by dyno jet to build power commanders for all new bikes. He is auto tune certified and has done excellent work for me in the past. The PCV needs to be tuned up for the current mods im just waiting for a performace air cleaner then I will buy the PCV 5 and tune her up to speed:D

More pictures below:eek:

The drone at highway speeds sounds good. Its loud enough for people in cars to notice you. Im uploading a video as I type this reply so the video will upload shortly:D

So it's not Street legal anymore?
I rode right past a CHP officer the other day he did not even pay any attention to me. There are Harelys that are way louder plus you can install a DP killer if you would like. The louder sound from the pipe is noticable to cars on the highway which is a big plus. I posted the video of the sound in another thread check it out and see!

Its nothing o worry about the stock system will do that. Once you addd performance air cleaners and pipes thats when the engine will need to be remapped.

Yeah perhaps I will. I plan to paint the mid pipe flat black to match the original headers
