Original muffler noise

Hi there! My 81 seca has what seems to be the original muffler (4 into 1) but I find the noise excessive. I do not like people to turn heads when I pass by
I was wondering if this is really stock, may I ask someone with a stock muffler to take a photo with a flash to see inside it?
Is there any easy/affordable trick I make to keep it quieter?

Thanks!

Sergio

 

Welcome ...what Seca model do you have 650,750 ? Sounds like you have an aftermarket exhaust ...should be a 4 into 2 ... My Seca has a 4 into 2 MAC exhaust

 

it is a 650 with this muffler:



Looking inside, looks like it goes direct to the tubes that got to the engine..

 

4 to one is not stock. 4 headers into collector box into 2 pipes is standard for 750 xj Seca. Something similar for 650 I assume.
No direct pictures of exhaust, but this may help:

US only has an 82 seca this link shows exhaust components, 81 xj650(Seca) would be a euro model

all are 4 to 2

 

Oh bummer, than this is not the stock muffler, so it must be a "loud is better" version... Can anything be done to silence it a bit?

 

a baffle could be inserted or stuff it with steel wool made of stainless steel (kitchen product) and retain with screen

if you can remoe the cone from the muffler you can wrap it with some fiberglass

Hard to tell from your picture, but if the muffler and head pipes are two pieces you may be able to fit a different muffler to it. Still wouldn't be stock but may be a quieter sound depending on what you can find for a muffler to put on it. I work at an exhaust shop so exhaust is kind of my thing haha

 

It is unfortunately one piece, from engine collector to end of muffler... i will try some stainless steel scrubs first... my neighbors are starting to complain while I am trying to colortune and balance it..

 

Throw it away and get a correct exhaust system. It will sound better (and quieter), and probably run better , too.
