I have a really bad dent on one of the runners from my skunk2 header (hate it because it sits low and has bad clearance) I would say its 50% crushed. But the thing is I heard if its just one runner it won't be noticeable for the loss in power. Please help.

 

depends...do you FEEL a loss ? in theory yes there would be some loss but nothing major,

 

I haven't before but now I do. I know you're probably thinking its something else but I checked everything too. Basically my whole exhaust system is sort of messed up in a way. I have an rsr exhaust and is pretty old that I tried to keep it alive by going to the muffler shop and repairing it.
