Wassup i have 2 dents on a header i would want to know if that would effect my performance in any way on the dyno. here is a pic of the 2 dents.

 

upppppppppppp

 

bummmmmmmmmmmmmmmmmp

 

It is hard to tell how deep the dents are in the picture...

 

Also good to know the build specs and diameter of the exhaust. having those dents may improve your power output if the headers are actually too big for your build....... or you read into the "D" shape exhaust velocity theory........

Better picture and more specific info is required to make any sort of judgment call on this!

If you are really concerned You could remove the primaries from the slip collector, take the dented portion to an exhaust shop and see if they can expand/put them back into shape. Or you could try it yourself, carefully, with a pipe expander. Careful not to go too far or they will leak...
