Ok so I have posted this before, but am still confused about a few things, I have the mbrp turbo back exhuast and this system is hooked up to all the stock hangers, right now I still have the cat in, but the system is all over the place, there is way to much movement, the pipe hits the shock, rear leaf spring and the tip hits the body, tighting clamps doesnt seem to do anything, does everyone have this problem, If I had the system welded on would I still be able to change my cat in and out? please help this is one of those things that just keeps bugging me.
