Cleaning out inside of drag pipe?
 

Can you take your pipe off and spray a good degreaser in it and let it soak and use a water hose to spray it out to clean up the inside of the pipe a little. It is an FTZ out of frame drag pipe for a 400 Sport.
Thanks!

I don't see why you couldn't. But remember the oil residue on the inside of the pipe helps to keep it from rusting!

Use paper money, $1s and $5s are best. Soak them in race gas and stuff a couple hundred through each pipe. Costs about the same as a weekend of drag racing :-)
