just got my megan racing header today got it on today also not to bad relatively easy waiting on my axle-back should be here sat. or sun.

 

how the hell do you add pics?

 

how do you know if your header has a leak?

 

There's a sticky at the top of the forum that tells you how to do it.

 

A big leak is pretty obvious, exhuast fumes and loud noise.

For smaller leaks you can dust everything with flour to help you find it.

Er... and the other way is to just take it in and let the shop do a smoke test to find leaks.

 

One other way people mentioned on here is to cover the holes and fill it with water (off the car, of course), then look for any drips/leaks. Past Megan's leaked often from around the O2 bung/collector due to bad welds, but not sure if that's still true currently.

 

and that's one of the reasons I made the switch to a J's Racing header...

 

If the header is already on the car you can check for leaks by holding you hand over the muffler tip. If you hear noise still you obviously have a leak.

With my previous Megan headers I could hold my hand over the muffler all day and my Fit would run fine. Sounded like a plastic bag in wind.
