A plug in the stock exhaust?

[muppetwagon]

I was sanding and polishing the stock header and noticed something. There is a rubber T grommet or something where the end of the header and pipe meet. This thing looks like it is there to create back pressure, without it, the header and pipe transition is almost a perfect match.

Is it a good idea to keep it there or can I remove this thing in hopes of a better flowing exhuast?

is it the jato 2.5 plastic exhaust? if it is then leave it in there. on mine i saw the rubber was a bit messed up so i just pulled it out and there was a small copper tube about ½" long the same diameter as the pipe aswell. anyway, after running it for a few tanks the pipe melted where it meets the header, so i guess its something to drain the heat away from the plastic, as copper is a good conductor of heat (i think). also, removing it wouldnt do anything because the diameter of the stinger is smaller than the diameter of the rubber thing so it woundl't make much diffrence to the flow of the exhaust.

i took mine out with out any problems, i also drilled the stinger and shortended it. it had so much power, the pipe had startd melting but only because i had the header right on the pipe....

Ahhh...thats what I was kind of thinking as well. I was thinking of opening up the stinger with a drill bit if I could loose the rubber grommet. Now the pipe will melt if I do remove that, so back to buying a good single chamber pipe.

Thanks for the reply!

Gasshead:

How far away is your header from the plastic pipe.....are you using the full length of the coupler? HMMM...maybe enlarge the rubber grommet opening and stinger?

Just poney up and get a single or dual champer pipe
