So After installing the greddy kit the passenger side muffler didn't quite fit because of a box with hoses was blocking it. They removed the shield and it was a tight fit. After bolting everything up there is a big space between the mid pipes and gasket and there is a loud leak. Installed Megan test pipes with greddy Evo3
Anyone have any advice ?

 

it should have came with a relocation bracket to relocate the box. also if the test pipes etc dont line up perfect the flanges on the greddy aren't so good so it will bend and have a slight leak. everything needs to be lined up perfectly.
