Stubbying Exhaust
 

Hi All

I've been tinkering with the idea of stubbying my exhaust for a while, and now that I have a rivet gun by my side, I'm seriously thinking of doing this butchery.

My question is:

Does it matter which end you cut the exhaust from to stubby it, i.e. the outlet end or the link pipe end. Is any end harder to put back together than the other - is what I need to know.

On another note, are stubbied exhausts legal (considering that I'm stubbying a road legal exhaust, with baffle)

Any advice welcomed.

Thanks.

what make is it?

it depends if you want to keep the logo on the can (if there is one)

i guess the are not legal, due to the noise, but if you leave the stamp on saying for road use, you might be ok?

Technically illegal, but with the baffle in you'll most likely be fine.

I cut from inlet end.

Thanks for the replies guys/gals.

YC: I haven't seen the internals of an exhaust - Are both the inlet and outlet ends the same then?

Pretty much. Sometimes one end is welded, but you don't know untill you chop it. All you have in there is a perforated tube right through the middle, that fits into the end caps. Around the tube is wrapped some fibreglass.

Getting the endcap back on can be a PITA.

microns are a PITA to stubby

i ran a bmw r1150 around for 6 months with a decat y-peice and 1/2 a remus can that upon first use blew any remenants of baffle 50ft out the back of it! i had to use it like that, sounded louvrely!!

How many times do I have to repeat this?

You do not legally need a BS, EC, E or any other markings on a bike exhaust. As long as the sound emitted is not what an MOT tester would consider too loud it is OK.

When was the last time you saw an aftermarket car exhaust with any EC, BS or E markings on it. Same applies to bikes.
