I don't know what to do,I was hoping to find info here but I didnt.I saw that there was a dead end pipe on the exhaust between the cat. conv. and the first muffler.I want to cut it because I think that it holds up gases.its in a form "T". should I do it. because I have seen these kind of things on a scooter.

 

Leave it alone. It dampens the exhaust harmonics at certain rpm's.

 

how do you know?And do u know how it works?

 

Look up Helmholtz filter.

 

I only wish my J's Racing exhaust had one of those. *sigh*

 

Hey, if you don't know what it is, cut it off!

 

Hisss...

hehehe j/k
