Hi I have a 2016 iron 883 and was looking for exhust ,but in the mean time i was wondering when taking the stock baffle out do you still have to do a tune on it

 

My 2004 is a lot older than yours, but I stopped at my friends on my way home with it and he got out a long rod and stuck it in the muffler and gave it a hard coupla wacks with a big hammer and WOW that sounded so much better. Carbed so not worried til I change the air cleaner. Good luck with those future modifications!

 

I was talkin to Buzz, the owner at Cycle Shack. He's retiring so you won't be able to get CS slipons in future but there is still some stock I believe mine are MXL 130. I would keep your originals because stricter emissions and noise regulations might come in. Some areas already have these. - A tip for getting the stock ones off.. theres a slit at the front edge of the muffler where it goes over the exhaust pipe. spray some WD40 there and rotate the muffler.. Mine were so tight, I had to use that slit to bent the metal back a bit to put the WD40 in there. Once it got in they rotated and came off pretty easy.

 

By just pulling the baffles, it will be louder but you will lose low-mid range torque.

Perhaps use Thunder Torque Inserts from DK Customs...an inexpensive fix to the torque issue and will deepen the tone. Check out their website for videos...they have vids on how to remove the baffles and the difference with and without TTIs.

It is always a good idea to get a tuner if you plan to do performance mods.

Good luck.

 

to answer your question, no... unless you want to. your bike will run a bit better with a tune but, it's no biggie. give DK $20 for some TTIs until you get some pipes and an a/c for your unavoidable rite of passage stage 1.

Removing the baffles will:

1. Make the exhaust note much louder and allow additional polluted exhaust gases out.

That will most likely result in DOT (Noise) and EPA (Pollution) violations. Depending on where you live that means traffic tickets.

2. Reduced back pressure.

This will reduce your "low-end" torque, but will also increase your "high-end" torque. This is why racing engines are always run without baffles. To racers, top speed is more important than how fast they're off the line.

3. Engine will run cooler.

Since the exhaust gases flow without restriction the engine can shed heat more efficiently. That's a bonus on the air cooled Harley motors.

Your O2 sensors and ECM will automatically calibrate to accommodate the baffle removal, but if you also have a high performance (high flow) air cleaner, you should get an aftermarket tuner to do the recalibrations.
