decarbonizing exhaust

[kygreen229]

will decarbonizing exhaust help any with overall top speed? everything is pretty much up to par now as far as being mostly stock on my 87 elite se50..and she is runnin pretty well. i want to cut open the exhaust and get all that stinkin carbon outta there!! the pipe is pretty freakin heavy when its off and im guessin its cuz of all the carbon build up. my dad is a welder for an occupation so gettin it back together wont b a prob. just wonderin where the best place would b to cut it? and how to get the carbon out..scrape it,,burn in it out? thanks dudes!

no need to cut it apart, there are two good ways to clean it without cutting.

chemical cleaning will do the best job, but the chemicals involved are relativly dangerous.
the easy way is to throw it on a campfire, or in the grill, and burn out the carbon. then just put compressed air to it ( after letting it cool, of course) and poof! decarboned, and in dire need of paint.

If you use gloves the Drano method is best. Just be careful and you will be fine. The results are much better than the camp fire method in my opinion. Look in the tech docs for the Drano (lye) method. As Spreetard said it can be dangerous but so can a camp fire if your not careful.

Polini does make a pipe that is rebuildable, its called the smoking gun

cool thanks for the replies guys. i ended up cutting out the back side of it so it was nice and easy to weld back together. suprisingly this scoot has been properly jetted and running well all of its 22 years cuz the exhaust had almost no build up in it! i was pretty pumped in a way..kinda was hopin for some just cuz it might have made her a little more peppy when cleaned:) question tho..the burning way or the chemical way,,doesnt that burn out the packing inside there? then the pipe would b considerably louder or no?
