ok so i have DNX headers/downpipe. and an Ebay test pipe (high flow cat). anyways i can NOT get them to completely close the gap between them. I've tried unhooking the mid pipe to the test pipe and it still wont close the gap to the downpipe.

so i wanna know if anyone knows any other way 2 make them connect. i'm not too crazy about welding it either. I also thought that mayb it could just b my downpipe, cuz i havn't really heard of DNX too much( don't ask y i got it)

thanks

 

dnx is a dynomax brand, which is actually a pretty well known brand. are you sure there isnt a gasket that is supposed to go between the pipes?

 

the gasket makes the gap bigger. idk y but it seems too

 

anyone know?
