Exhaust mod
« on: June 24, 2013, 06:16:21 PM »
Alright BROs, kinda excited for this experiment. Lol. So I chopped off the exhaust maybe 3 inches off from the tip. Took the baffle out and cut in half. Then weld the baffle inside so it's not too loud. Baffle is a little exposed so I'm gonna paint it with a high temp all around. It's currently in the process so ill post some pics and sound afterwards xP

Keep us posted, Diogg. Would definitely like to see a video with sound.

I just bought a drill bit extension and drilled out the inside of the baffle.  another member did it also.  much cleaner and easier than all that cutting.  I'm really surprised Low and Mean didn't think of it.

I did both, I used the Low and Mean method, which definitely worked, but was not the same impact as drilling out the back of the baffle with a hole saw....  To give perspective, and remember exhaust sound and tolerable noise level is very subjective between riders, I will give a rating... On a scale of 1-10, 1 being stock and 10 being what my ideal level of exhaust sound and volume would be... If stock was 1, then the Low and Mean drill outs brought it to a 4.5, and the hole saw drilling out the rear of the baffle is an 8.  I am going to order the Low and Mean megaphone with baffles and that should be my perfect ten.


On a side note, the Low and Mean video did address that concern, as they said they want to provide a DIY that everyone can do with just what is laying around their house. Most people have drill bits and a power drill, which makes their DIY drill outs very easy and does not require a trip to the hardware store.  On the other hand, drilling out the rear of the baffle requires a 10-12" extender and the 1 1/2" hole saw, which most do NOT have around the house and does require a trip to the hardware store. Which in my case cost me about $25 bucks at Home Depot.


Cheers brother, good luck with the drill outs and post up some video like Fearthehog suggested... We are all anxious to see how each other's Bolts turn out... ;)

I think someone commented to Low and Mean (on Facebook maybe?) about why they didnt just go to drilling the inside baffle. They replied something along the lines of, its a more advanced mod requiring tools that not everyone might have.
In my opinion, cutting a hole in the center baffle wall was alot easier and had much better results. But I did have to go out and buy about $20 worth of tools.

There is one baffle, welded as part of the inner diameter of the last half of the exhaust can. When you remove the tip you can see the inner diameter, if you shine a flash light the rear of the baffle is visible about 10 inches back.

I did it your way also.  Just had to buy a drill bit extension and went right to the center of the baffle.  much cleaner with better flow results.  i noticed a small power gain on take off as well.  ;D

I used this Milwaukee Bi-Metal 1 1/2" hole saw drill bit...  With their 12" extender bit.


I only had a 7.2V Black and Decker POS power drill so it took me a long long long time to wear down the aluminum and I ended up punching through it with a hammer on the end of the extender bit to finally punch it through.


Just remember to put a pilot drill bit on the end of the extender as I forgot this step and the piece of aluminum rear baffle I could not get out after until it ended up flying out the exahust and going "ping, ping, ping" down the road when I test road her after... LOL!!!  :P

I bought the same ones BoltiansMC bought...along with their pilot bit (probably didn't really need it since I have a set of nice drill bits already).
