Title: Standard exhaust modification
Post by: Jacog on Wednesday, 25 October 2017, 05:33 AM
Hi
I like the look of standard cans but they are a bit too quiet for me.
So I started modifying my original exhaust.
Lots of information and help I found on http://www.gsx-1400-forum.de  :clapping:

I bought spare exhausts because I did not want to drill my own, in case that something will go wrong.

I start by removing the rivets from the back plate.

(https://preview.ibb.co/fcKUT6/20171021_153334.jpg) (https://ibb.co/bPQQ1R)


Then I drill the can wall (I used a 44mm hole saw)

(https://preview.ibb.co/m4UUwR/20171021_155007.jpg) (https://ibb.co/bYVDO6)


About 13cm deeper is the next wall.
Put a piece of rod and bend the exhaust inset there and back, up and down until the weld breaks.
(this work lasts forever)

(https://preview.ibb.co/gjzUT6/20171024_172826.jpg) (https://ibb.co/fTYZvm)


I'm going to use a 45mm stainless steel tube to make a new muffler tip.
(https://preview.ibb.co/f0kuT6/20171024_172729.jpg) (https://ibb.co/dS9M86)


I have cut tube (40mm) and perforated tube (80mm) and weld together.
(https://preview.ibb.co/dDCJo6/20171025_191637_001.jpg) (https://ibb.co/d5UL1R)
(https://preview.ibb.co/nrBHGR/20171027_142839.jpg) (https://ibb.co/cCU4wR)


Ready tube weld into can.

(https://preview.ibb.co/mOdKVm/20171027_161216.jpg) (https://ibb.co/gE0oO6)


I have enlarged the back plate hole to fit the 45mm tube. Three rivets and back plate come back to the place.

Hi
"I like the look of standard cans"

These are the words I thought I'd never see! I tip my hat to you Jacog for coming out in public  :hat:
Maybe the forum is programmed not to show offensive images  :whistling:

Cheers

Good pictures. Maybe you can test the sound in "step one", before you continue? It would be nice to know.

Great work - I was thinking of getting a bazooka and doing that for my K 5 - yes I would love to convert to twin but then wouldn't get the bike down the side of the house into the garage !  :smile2:

I'd love a set of std twins but just can't find them here in OZ but I do have the twin conversion just with Delkevik slip ons.

Hi Trav Man, either Sweaty or Snapey have a couple of sets of twin exhausts I seem to remember. Might be worth asking . . .

Nice mod Jacog,
I picked up a pair of standard twin pipes because I liked the look but I was surprised at how heavy they were compared to aftermarkets, do you have any idea how much weight you threw away?

Cheers,
Rick

Post by: Jacog on Friday, 11 May 2018, 03:08 AM
Hi
No much. Maybe 0,5kg each.
Title: Re: Standard exhaust modification
Post by: Jeykey on Monday, 11 June 2018, 02:13 AM
I love the standard exhaust on my K5. Any minor gain on weight ? I'm thinking of doing the same; buying another one case anything goes wrong. Especially since here in my country the cops are checking how the bikes are. When they're not stock its a pain. `Cause of the new to be roadworthy tests for bikes. Everybody's being pulled over. Lights, exhausts, top cases, ...
Title: Re: Standard exhaust modification
Post by: Andre on Monday, 11 June 2018, 02:41 AM
Lots of strictness here too. As long as exhausts (and lights) have an E-number, the cops are happy - as long as they don't notice that your exhaust can has been manipulated!!! I know (have been told, read) that some other countries (Italy, Switzerland) require a paper to go with the number (exhaust). Anything not having an E-number and is not stock, you have to have a paper (general operating permit) where your bike is listed or it has to be entered into the bike's papers.

Yep, basically same here. Its Europe, by the way.

The stock 1400 mufflers don't look too bad on a Katana either.

Depends on how European law is put into national law and enforced. My impression is that there is more leniency in GB, at least in regards to exhaust cans.  ??

I think there are some things where Europe standardised the rules for manufacturers - Euro4 pollution and noise limits are good examples - but the rules for individual vehicles and their owners are widely different in each country. It would be a lot harder to normalise these rules because they have been in place a long time and people would be very resistant to those changes.

A lot of people complain about UK rules and regulations but they are actually quite sensible compared to some other countries.

A few years ago the police would be out on a Sunday pulling bikes in and checking their number plates (with a ruler), exhaust, tyres and the riders visor and issuing a complementary voucher to pay money into the police Christmas party fund.  Now as long as you ride sensibly they tend to leave us alone ignoring iridium visors, loud pipes and small number plates (probably too much paperwork for not much gain), if you ride like a tit they will do you for that and add in the exhaust, plates and visors for good measure.

I dont ride like a Tit Occifer!!

Was once pulled up when I was just 18yrs old whilst playing out on the bikes with my mate (who I still ride with).
The copper asks my mate his name....
"Norton" says my mate..
The copper says to his fellow officer still sat in the car "Bill.. We have a Norton on a Suzuki"..
He then says to me "And who are you"?

"Speed " I replied (yes really)..
He said "Bill, we have a bloody idiot here"..

My surname used to get me off many times..

Reminds me of a time in a mate's car who was racing another mate through town & a cop stepped out in front of him when he was doing about 80 in a 30 zone.

Convo went something like

How fast were you going?
30
Bollocks, how fast really?
30
Ok then, how fast was your mate going?
Oh much faster than me, did you see how far in front he was?

Somehow he got away with it too  :grin:

Hi Jacog

Great write up & pictures, I am considering having a go at doing this to the standard cans that were on my bike when I bought it as they look to have been tampered with anyway, could you let me know what you used to open out the end plates please, did you use the same 44mm hole saw?

Thanks

Pete...

I remember the end plates were very hard stainless steel which the hole saw didnt even scratch!
I ended up taking them to work and drilling out loads of small holes to form the circular cut out..
I laso finished to hole with a Dremel.
