Resonator delete is my new fav. exhaust mod!

I did my first ever resonator delete mod. I really like it, and it costs only about $50-60 CAD, which is perfect because I'm cheap AF! haha

On the BMW F750GS, the resonator box is located between the catalytic converter and the muffler. It's about an 8 lb box that silences the sound and helps to meet an 80 db EPA limit. Replacing it with a resonator delete pipe shouldn't have any negative impact on performance, emissions, or set off any codes.

Doing this mod gave my motorcycle a deeper tone, with more growl, and more volume. The stock muffler is still in place, providing noise suppression and back pressure. Yes, the bike is louder, but not loud enough that it would bother me on long touring trips.

There is a bit of a decel pop, but it's a very mellow base pop pop pop, like a gurgle, rather than a trebly POP! POP! POP! tin can sound that you might get from opening up a muffler.

The product was sent to me for free by Temu as a promotion for me to try it out / make a video about. I wrote back in June that I had good experiences by cheap little stuff from them. I don't know how long this pipe will last, but even if it's rough shape after a few years, I can either spend 10 minutes swapping the resonator back in, or spend another $60 for a new one.

It got me thinking about all of the thousands of dollars I've spent buying new and used exhausts, carb jet kits, fuel processors, etc. This was easy, fast, and cheap, with no negative impacts on my motorcycle's smoothness or responsiveness.

Here's my video showing install, before and after sound clips, and addressing some of what I already touch on in this post:

These are the timestamps so you can just skip to whatever part/parts might be of interest to you and skip past the rest:

0:33 Installation
1:25 How To Get It For $1 (or $36)
3:44 Before Vs. After Comparison
5:30 Negative Impacts
6:22 Engine Codes / Errors
7:07 Do I Like It? / Should You Get It?

PS: The new resonator delete pipe only weighs like half a pound, so my motorcycle lost 7.5 lbs, plus a few more with the switch to a lithium battery... but the resonator is at the bottom of the motorcycle so I'd be a liar if I said I felt the difference.

PS again: The only issue with the install/product is that the OEM heat shield can be tricky to get on, and it touches the delete pipe itself. The mounts for it should of been welded in a few more millimeters over.

Sounds waaay better. I always up the volume on my bikes to an enjoyable (but not obnoxious) tone. Braaap for the win!

There's a sweet spot, the goldielocks of exhaust volumes, not too quiet, not too loud, juuuuust right.

And I found it on this bike without having to spend hundreds of dollars... I was really surprised.

You could say I was...


Baffled!

(har har har)

It sounds like a v-twin (my fave configuration) but when I looked it up I see it's a parallel twin ... must have a 270 firing order.

Nice video and nice and cheap sound upgrade!

Sent it over to my buddy with a very similar bike for consideration!

Did you test to see if it’s stainless or steel? i bought a cheapie pipe off Ali, lasted 2 years.

Nope, but given how poorly the BMW headers themselves hold up on these bikes it's not really a concern haha. Are you suggesting just a water test or is there something else I could do?

I came across a few people while reading up on this on forums who have had them for years. The longest (timewise) guy was 4-5 years. The most km was 60,000 km. I figure if I get 4-5 years, or 60,000 km, AND I still have this bike, I can spend $60 for a new one then and still be happy.

Yessir, you got it.

I had one of the old parallel twin GS from the generation before this... As a bike, it was, completely fine... It was just so ******* vanilla though. Like a girl who's boring in bed, but doesn't give you any issues. You're sitting there thinking "This is okay, this is nice... but do I really want this for the rest of my life?" - I actually preferred my comparatively anemic 650cc GS more because at least that single cylinder thumper has some character to it.

But these new twins, with the 270, they got some spice, and they got some balls! Totally different animal compared to the previous gen. Why'd it take manufacturers so long to figure this out?

Nice video and nice and cheap sound upgrade!

Thanks very much!

Those like on your video may be an option for @mimico_polak ??

Use a magnet.

What're we spending my money on now? My aftermarket pipe that came with the exhaust sounds fantastic in my opinion....so I'm not changing a thing!

Still have the stock muffler from the previous owner, which are laying around somewhere.

I'm referring to the motorcycle bud.

You can check stainless with a fridge magnet. Put the magnet on the straightest part of the pipe, of it holds itself onto the pipe it's probably steel.

Don't try the bends, bending, forming and welding stainless can make the worked area partially magnetic.

There isn't a difference in performance, just life expectancy.

Yes I like those BMWs a lot. But for now....you know...

With that link pipe, it's got character ... and storage possibilities ... not sure about the gas range but it's gotta be better than the Scrambler. Seat height seems low enough and there are usually options to lower it further.

For when you sell the Scrambler maybe.

 

[GreyGhost]

it holds itself onto the pipe it's probably steel.

Or 400 series stainless. Acid test tells a little more but meh. It's cheap and already installed. He'll find out in a while what it is made of.

Wait, why is my motor glistening?! Oh for **** sakes...​

Quick backstory for context: I wasn't planning on buying an F750GS. Someone was leaving the country permanently, needed it sold, and we literally did the deal the night before he was leaving Canada for good the following morning.

Part of the deal was that the bike needed a new inner oil pan (stupid ******* BMW design) and I would pay ($160+tax) for that part. This was weird to me because the dealer literally did the last two oil changes... so either BMW broke the part this time, or they broke the part last year. Either way, they were charging the customer for their **** up, and I was going to pay for it.

Owner had way more important things to deal with before moving to the US than to fight with them. Both the dealer and the owner told me there was nothing else wrong with the bike, so fine, for the price I was getting it at, I wasn't going to fuss about it either. BMW wanted like $265+tax to do the labour. **** that. My buddy Ben came over and we got down to business. Two guys, one cup... of gasket maker.

And the thing ran great! And between our nice dry gasket, and the clean bill of health the BMW dealer gave the bike, I was confident the bike was all set and it was time to start modding.

Temu sent me the resonator delete pipe on, some cheapo hand wind guards, and little visor for the speedo/tacho/screenthing. I scored a second hand Touratech seat off of marketplace for $300. I thought everything was coming up Milhouse!

Today I put the bike in my truck bed, and saw it from a new angle, and the sun hit it just right, this beautiful glistening motor shining in the golden afternoon sunlight.

WAIT, WHY THE **** IS MY MOTOR GLISTENING?!

Probably because it's all ******* greasy in front. Probably because the ******* valve cover gasket is blown.

For **** sake! I really do not want to do this job myself. I'll **** around with a buddy and lather ourselves up in gasket maker all night long if there's a part that's easily accessible, but I really don't wanna take off 582 plastic parts and fasteners, lift off my gas tank, and open up my motor.

BMW guy seems to be familiar with this issue. Apparently it's not unusual for these things to bleed oil out of the valve cover after only 8,000 KM (How do you say "WHAT THE ACTUAL ****, GERMANY?!" in Japanese?!)

I think BMW's first strike with me was making the customer pay for the part that they themselves most likely broke.
Strike 2 was them missing the valve cover gasket when they told me everything else on the bike was fine.
And maybe Strike 3 is the "Oh, your valve cover is already ****** at 8k km, yeah that happens, lol oopsies!" (not their actual words, I'm just being jaded).

Long ******* rant to say I both love and hate this thing right now lol



First noticed the wetness and dirtiness. It's definitely been there for a while. I've only put 10 km on this bike dicking around on private property.



Left side is worse than right side.



It almost looks like the top of the valve cover might also be wet, maybe I should check up there after posting this...



Right side looks fairly dry until the very front. Maybe because the kickstand stand leans left, maybe just coincidence.

Anyway, hope y'all having a more fun evening! Thanks for coming to my rant!

Where's the "Loud pipes don't save lives!" brigade?

Anyhow, I'm the same as you. I like tasteful. Not obnoxious. Not sewing machine.

I've ridden enough miles on 2 wheels, and spent 3 decades behind the wheel of 18 to know that being heard does actually matter.

No offence intended, but I've spent enough time on the road to know that it doesn't matter as much as you want to believe.

How many decades have you spend behind the wheel of a 18 wheeler where you can’t see every square inch around you and sometimes you hear vehicles before you might otherwise see them?

Because as someone who has actually done this, I assure you, it does matter. Over the years it’s stopped me from potentially squishing a few riders who didn’t seem to understand loitering around in a trucks blind spots is poor practice.
