Everything this this gentleman demonstrated is accurate. Just did this about a month ago to my 2021 Scout, and measured dec. with a phone app, I measured 83>84 dec. @ 4 ft. After removing just the 1st baffle, I measured 89>90 dec. Not sure how accurate my phone is, but measured both times at same distance. My experience was a more noticeable increase than what the video portrays. After drilling out baffle, and pulling out the disc, I shoved magnet back in, and recovered more of the shavings from drilling, followed up by a modified hose hooked to 6hp shop vac. Besides completely removing muffler, I do not believe I could have got it any cleaner. Regardless, bike sounds and runs great. Much cheaper than slip-on's, and is a good starting point to decide how you want your bike to sound. Mike
@@jimheidl1272 yes, if you search for it on UA-cam there is a lady that did drill both out. She does an excellent review of before and after. Video shows stock, 1 out, and finally all four.
Hey Mike! So... your engine has NOT exploded yet do to errant metal shavings?? I kid, I kid. Anyway, how did you modify the shop back hose? My SB20 should be here in a few weeks and this will be first order of business.
that is a good question, but from a post i read in the past, this will leave a hollow void (shell) and no interior parts. what I was trying to do, was just increase a bit the noise level. but, you have a good point.
Easiest and Most Sound Effective is Remove the 6 3mm Allan Screws at end Caps Pull Complete Baffles out Remove fibreglass Wrapping and throw in the Bin Get your grinder with Cutting Disk and Cut Off @ the end of Cats, Re IN stall, WIN / WIN YOU WILL BE A MUCH HAPPIER INDIAN OWNER COST = ZERO DOLLARS.
Uh, what about the metal shavings? There is actually a vacuum at times. I’ve seen bores destroyed from catalyst material being sucked up into the cylinders. It all doesn’t blow out.
@@kevinsweeney3428 I worked at the Honda engine plant test department for over 20 years. I’ve seen the destruction to cylinder walls from loose catalyst material being sucked into the engine. 4 stroke automotive engines I’m referring too. It can happen!
@@davepritchett He did remove only the first exhaust baffle. The catalyst is much further in the pipe on the opposite end. There is still another baffle and the honeycomb cat in the way, I doubt any of the metal shavings can get through those and that far into the engine, most likely they will eventually be all blown out.
the Indian's engineering team who managed the project of those exhausts to comply with the environmental regulation and other regulatory stuff should be agitated about this "modification". why we should bother about the exhaust mufflers, those things are there just to be changed or modified, the volumetric efficiency on the combustion chamber or other parameters non important on the engine is not that important.
Lol, there’s a difference between a freeway legal scooter for teens going to school . And adults transportation and sound to go along with your vehicle. In a car you can here it when driving because your inside and can notice a problem before it happens and poll over. It’s more important on a bike because you don’t have airbags in a protective cage. You would be surprised how often cars move over with out looking .
Did it to my 2023 Rogue. Spent $16 on parts from Lowes. Super happy!
thank you for sharing that you did it on your Rouge. It is really simple and does a really nice job, to enhance the sound.
Did it today, same rogue 2023, pretty good for now !

Did you drill 1 or two sets?
@@jimheidl1272
Just one in each muffler
@@mikeh4686 have you heard or seen any video of someone drilling both sets?

Does this impact the bike in any way? Performance or fuel consumption
none, or at least none noticed. I hope this helps.
@@SimpleWorks thanks mate
Why not take out the screws and just gut the whole muffler?
that is a good question, but from a post i read in the past, this will leave a hollow void (shell) and no interior parts. what I was trying to do, was just increase a bit the noise level. but, you have a good point.

The caps are just for show. The stock mufflers are sealed.
Post a video about it.
Do the baffles come out
no, just a part of the baffle, it would make it flow easier, and a bit louder, less restrictive.
Uh, what about the metal shavings? There is actually a vacuum at times. I’ve seen bores destroyed from catalyst material being sucked up into the cylinders. It all doesn’t blow out.
very good observation. thank you.
You can cut the pipes back past the first baffle and modify end caps too.
Are you sure you're not thinking of two strokes? 4 strokes have valves that would stop the possibility of anything being sucked in.

Hard to believe there are still guys trolling around out there using exhaust noise trying to get people to notice them.

@@longface6045 That is one of the basket of excuses/myths for being a public nuisance.
