modifying standard cans
« on: 14 March, 2014, 11:08:18 AM »
Having looked at buying a set of aftermarket cans and cringing at the asking prices
I decided to buy a second hand set of standard cans and gut them
Drill around the outlet pipe be careful not to press to hard as when the drill breaks through it tends to twist sideways off the baffle and snap(cheap pound line )
join up the holes with a round file ,
Once freed from the end take a suitable bar , screwdriver etc  and start to wobble the baffle side to side ,round and round it is only held in with two small welds tacked on to another baffle inside don't be tempted to  grab the end of the outlet with grips as its very thin and soft and will only fall apart if you twist it
( nothing is attached to the outer tube so don't worry about the outside finish )
Now you have a large open ended can, tidy up the rough metal blow a coat of heat proof matt black over the cuts and job's a good u'n.

OR do what I did fabricate a new end cap using a section of the original out let pipe and a few bits of stainless plate, it now looks like the standard end but has the extra DB killer removed .
I will try to stick some pic's up soon and maybe a small sound video .





I quite like the two pipe up the one side look
OH and once I paint the end cap you won't see my rubbish welding :008:

OK so been out today and the mods have resulted in a nice mellow sound under power
and a interesting noise  on the overrun :
I'm just a kid at heart :mfrlol:

I am about to cut the baffles out with a holesaw.  But before I do will removing them affect the back pressure enough to make the bike run ruff?

I've seen many redesigned standard exhausts on the 600's

All sound better than Oem

Have a look through all the pages on this web site   http://www.pjengineering.co.uk/products.php
If theres a gap i can get through it !!!

Some people pay for an IAM... I am mad.....

Thanks for the replies.
Will post my handy work next week with photos. Just like the look of standard cans but want them louder.
Cheers

 :062:  Will it pass MOT do you think - I like the look of the standard cans and prefer quieter exhausts but IMHO the MK1 is a bit TOO quiet -  need a bit louder so that cagers can hear you filtering  :mfrlol:

We're not talking 1970s open pipe Alfa 4 into 1 here :mfrlol: only removing the last piece of baffle out of the standard can .
With the fabricated end cap replacement on mine you would have to look carefully to notice any modification at all.
