Here is a DIY mod.

I had a set of Road Burner pipes put on my 1100 classic and I was pleased with the sound until I started riding with my "Harley" buddies. I had to make sure I started my bike first so I could tell that it was running! So after thinking and thinking I decided to remove my baffles! I couldn't believe the difference! It does pop if I'm sitting at idle and I "goose" the throttle real hard but not all the time. When shifting and decelerating I get no pop like some of the other guys I know that removed theres does. Now all the "Harley" guys want to ride in front of me instead of behind me! LOL

I have the same issues with my 1100 and the Shogun Ripsaws.
Gotta love it

Hey Sneeze, I have a 05 midnight custom, I put on a set of Cobra Dragsters. and I love it. Of course when you mess with the exhaust you will have to think about rejetting the fuel system. I put the Dragsters on myself and had a mechanic do the jetting on the carbs but I love it.

Food for thought

There is a lot of research goes into most if not all aftermarket pipes. All that I have heard sound good. Most but not all modified stock pipes sound good.

Last night at a bike night I saw and heard a modified V Twin that sounded cheap and tinny. The exhaust was loud but did not have that deep powerful sound that a V Twin can have. Most of the bikes like this I have seen are smaller V Twins the muffler has been totally gutted. With nothing left but the shell and no back end.

Something to think about before you get out the hole saw or grinder. You can save a lot of money but is that what you would want?

I agree totally Dave!

I totally agree Dave! I feel if your going to modify the exhaust system, look around even go to bike rallies or rides and listen to all the custom exhaust sytems and find the sound you want. I am not a fan of gutting stock exhaust, but as you said Dave it depends on what you want. I listened to a number of bikes that had my system installed and I love the low powerful sound they have, they are loud but they have a more of a throatie sound. I agree with you Dave, the sound most modified stock pipes have is cheap, they are not designed to run without baffles.

On a positive note, I took the plunge and decided to remove the baffle out of my 2008 vStar 1100 and I also removed the AIS using the instructions found on this forum, very easy and plugged the ports with 2 10X25mm bolts. In all the videos and instructions I have read about the baffle it was a straight tube?? Funny mine is curved and after I broke it loose (that was a bitch) it came out about 2 inches but something is keeping it from coming all the way out. Any ideas? Even with the baffle sticking out of the end it sounds so much better. It used to sound like a sewing machine on steroids. Now it sounds like it has some balls. How do I get that pipe out???

i read some guys DIY and he mentioned the 1100 specifically. and he said you have to attach a set of vise grips to the piece sticking out and hit it hard. apparently the part that is stuck inside right now has an expanded portion. so yeah you gotta keep working it. should come out.


see if this helps!

You do realize that there are cats in the 08 exhaust and removing the ais can cause overheating causing a fire/other problems?

Just a note, from personal experience relating to all sorts of wheeled devices, if you cut/trim/alter remove any stock parts, and want to return it back to stock (i.e get a defect and have to get cleared) you are rooted.

It is cheaper to buy a set of aftermarket pipes (yay curb burners) and put the stockers in storage. that way you can revert to stock to sell (although everybody loves after market pipes, it also creates the illusion of thrashing) and sell the pipes..

my 2 c, you are very welcome

why not just buy a set of stock pipes off ebay or craigs list and modify those.

I was under the impression the AIS was to help burn any excessive fuel. But I did not read anywhere were it could cause overheating or fire???

How do I get that pipe out???

After further research I discovered I had to get in there with a long screwdriver and open up the area around the pipe where it sits. Long screwdriver and hammer. After I opened up that area I was able to get the pipe out. I then slid in 1 1/2 Chrome inserts to the end and it looks fine. I did miss a few times and ding the end of the exhaust but I can live with that. If anyone has more information on removing the AIS and fires and overheating please let me know. I kept everything and i can re install it.

I cant comment of the fires. I did the cheap ais bypass dont see any issues. a vac line should not fill with fuel neither should the air tubes unless there are other issues possibly with the carbs flooding while sitting or float set way to high but even then ive seen cars with fuel issues that have completely soaked the evap systems with raw fuel due to a high or stuck float... anyway..

I did this on my 08 with the stock pipes honestly the cobra slash cuts i put on after perform better since there some what tuned for our bikes and can be jetted for the additional flow with out of the box parts. I know the price isnt just time and effort like modding stock pipes but the outcome is so much better.

did the cobra pipes require rejetting the carb?

you should always rejet to get your air fuel mixture correct after any mod. I did not have to rejet since my bike was fat out of the box due to my elevation. A good calibration kit "jet ket" will resolve a few of the factory issues like the strange vibration our bikes have when your just barley on the throttle.

OK...Have an '07. Did the "cut the first baffle out" and rejetted. Sounded great, ran great. Put on Cobra Longs, rejetted again, runs even better. Cutting the first baffle out made a HUGE improvement in sound. Going with the Cobras and dialing in the jetting made a HUGE difference. Also running the "chubby" pod kit....hats off to Shane. Best customer support ever.....Get the "Chubby" ....too easy

Cheap mod (if you can find a deal like this guy did) and IMO these sound great!
