Hello all!
If I mount the S&S silencers, is there a requirement to re-map the EFI and open up the intake?

No none needed but I did do the S+S air filter they sell also.

I also did the S&S pipes and the DNA hi-flow air filter, did not remap anything and everything runs great. I've watched a ton a videos about that and none have suggested remapping or Dyno.

S&S exhaust here too with no other changes and the 650 fuels perfect.

There is an ECU setting procedure. See Here:

Stuart is basically saying let the bike idle for 10 or 12 minutes immediately after fitting the performance filter to let the bike recalculate the fuel/air mixture. I don't doubt his advice but for all the aftermarket pipes that have been installed on 650s, this is the first I've heard of the procedure.

mwmosser · **Reply #6 on:** December 05, 2019, 08:30:03 pm

The ECU will recalibrate probably quicker than 10-12 minutes, most likely within the first few minutes. Stuart's point is that you want to avoid taxing the ECU with wide range of throttle inputs, thus his recommendation to let it sit at idle. I haven't swapped out my exhaust yet, but when I do, I'll do that.

Has anyone fitted the cams, air filter and pipes combo that are available for the 650.

I put a set of AEW silencers on my Interceptor. Looked at the S&S silencers and the price killed that idea as well as the fact that you cannot remove the ends of the S&S silencers and remove the packing. In my opinion the AEW silencers are just as good as the S&S, same design, any difference is minimal other than the end caps. I removed the baffles and all of the fiberglass packing from my AEW silencers and the sound is awesome. Loud, but not too loud, deep and throaty, and with a bark that will get attention.

You are quite incorrect what you stated below. The reason the S&S exhaust is pricy is because there is no packing! It is made of pure stainless steel baffles. Never wears out. Always sounds the same. The street version does have a very small cat in it.
Very high quality. That is why there is no end cap... but there is a baffle that is removable.

Well, sorry that I was not correct. All I know is that I listened to sound clips of the S&S and AEW silencers and couldn't tell any difference. When I removed the packing from my AEW silencers there is definitely a difference ... noticeably more roar and bark. Can't do that with the S&S. My AEW silencers can't wear out now either.

I can still put the db killer baffles in to quiet them down.

darmahman · **Reply #11 on:** December 09, 2019, 03:45:10 pm

Of course they don't "wear out" but the packing will. Maybe that is what you want.

mwmosser · **Reply #12 on:** December 09, 2019, 05:09:16 pm

Never heard of pulling out the packing on an exhaust, but it makes sense, I guess. I know it changes the sound, but does it change the airflow/back pressure at all?

The problem is the sound clips. They sound the same if it is an open pipe with no mufflers or completely stock. It's like trying to tell which cheese tastes best by watching a video.

Well, I guess your ears just don't work.

jimku · **Reply #16 on:** December 09, 2019, 09:55:26 pm

Removing the packing doesn't increase the loudness a whole lot, it just removes the mellowness the packing imparts and adds more "bark". You notice it most under acceleration or when quickly revving. At any rate, I love the sound of my AEW silencers.

beagle · **Reply #17 on:** December 16, 2019, 06:28:18 am

Its been too hot to ride, so what does one do except buy bloody bits for the bike instead. I put some emgo cans on and they are a bit unsociable, so I ordered some eBay DB inserts, along with a high flow air filter and a booster plug to help the ecu a bit. Hopefully everything will here by Christmas so I will have a new year project. The booster plug was sent from Denmark to Australia last Wednesday night and delivered that Sunday morning. Gobsmacked at the delivery with DHL, across the world to my door in four days. It takes two bloody weeks to get anything that is shipped locally over here. Anyway, I'm hoping it will liven the toy up a bit.

gizzo · **Reply #18 on:** December 16, 2019, 10:10:06 am

Saw/heard a 650 CGT with S&S pipes the other day. Damn that is a good sounding motorbike. Im sure the AEW sounds lovely, too.

Dr Mayhem · **Reply #19 on:** December 16, 2019, 02:26:26 pm

Is there a reason people aren't fitting the race only version which don't have the cats, are lighter and less money also?

Racing license required to purchase. I don't have one, do you?

LoL, I can purchase any product S&S has in their inventory, including their race only items any time I want.
I don't have a racing license and I'm not special in any way either

Cool! I don't have that ability. I just saw the new AEW mufflers that look like the iconic Bonneville mufflers. That "snake swallowed a cat" look and they mount horizontal, not sloping. Seriously considering those.

I just had my dealer do the cams and 11:1 pistons on my '21 Interceptor. S&S pipes, K&N filter with DNA airbox removal. She's noticeably more peppy, but I'm getting severe engine knocking under heavy throttle in 6th and occasionall 5th gear. Tried pepping up the ocane, just in case, but it looks to be actiming issue.

Jack Straw · **Reply #24 on:** March 30, 2021, 02:16:47 am

Welcome to the forum Black Campbell

With respect to the knocking or detonation noise I'd expect the installer to rectify that. Engine changes like compression, camshaft, intake alteration and exhaust changes are 75% of the job, making it run right is the final 25%.

It seems like they need to finish the job.

Back to the dealer. With those mods you'd really need something like a Power Commander or a PowerTronic ECU tuner, which needs to be tuned on a Dyno. If they installed the pistons and cam, but not the tuner, then they need to do that and tune it properly.

Warwick · **Reply #26 on:** March 30, 2021, 11:06:54 am

My S&S pipes have a race only badge but still had a removable baffle which I removed. Sounds great!
Would mind Revellry's header pipes too.
Cheers and beers

Speaking of S&S mods, has anyone done the 900cc big bore kit yet? I've very interested in that when it becomes available again.

The 650 isn't slow...it's a nice enough engine with some character and pep...but it's certainly not fast, haha.
