Title: Denippled my exhaust.. sounds horrible!!
Post by: armoredpig on March 11, 2010, 04:20:09 PM
Hello!  I read somewhere that if you cut off the moped nipple from your pipe that it would sounds a bit more agressive..  So I tried it and would like to warn you guys not to do it!

My exhaust now sounds like an angry frog trapped in a soup can  :icon_neutral:



Heres a video..

Guess that nipple was there for a reason..  Any suggestions as to how I may fix this?

I am sad.

What nipple are you talking about? It still sounds pretty much like a GS to me. Maybe a little uneven, but either way I've never really considered the GS to be all that great sounding.

Inside of the stock can, theres a smaller pipe that protrudes outward somewhat its about 3/4" in diameter and makes the can look like something off of a moped, so I cut off about 2 inches of it (mostly for looks) and now the exhaust has a lot of pop at idle (in a very conspicuous way)..

I might get used to it--but at the moment I'm kinda wishing I didn't do it  :nono:


EDIT:  Took it out for a spin and the sound is kinda growin on me  ;)

DRILL HOLES!  Start with three or four smallish holes in the baffles surrounding the pea shooter (nipple).  Enlarge the holes/add more until you reach the throaty sound you desire. 

p.s.  As it gets throatier, it also gets louder.  Beware.  When I had my '99, I completely removed my baffles.  I loved the sound.  My bike also had a Uni foam air filter, and was rejetted.

Ah I'm a little weary of drilling holes because I fear the rejet (idk how)  :embarrassed:

The bike is sounding a little... old school british if that makes any sense?

One solution: Look left (my present avatar). The infamous Soup Can Mod.

The pictures died on the thread. I haven't fixed them yet, but my avatar is one of them.

If you look up just one post in that thread, you'll see a more typical drilled-out exhaust. Mine had the whole rear baffle chopped out.

you know, there are plenty of opinions about aftermarket pipes just on gstwins, even a few guides about how others made their own carbon fiber duals.

don't ruin your stock setup. sell it pristine on ebay and pick up a jardine or v&h. easy cheese.

It certainly looks better  :)

I've changed my mind, I am sorta liking the denippled muffler. 

DoD, thats some fantastic thinking!  I'll have to try out your Soup Can mod later!

I'm changing mine back to the stock exhaust. I currently have an open exhaust. Well, it has a muffler, but the muffler is so big I can literally stick my fist in it. So it's basically an open exhaust pipe. It's fawking LOUD. I'll record some video of it and post it up before I switch back to stock...

I ran my bike with and without the muffler, and all the muffler did was tone down the raspiness of it...
