im about to start my swap im puyying my built ls vtec into my crx i was looking at the stock ground clearence and theres not alot lol it is currently at stock ride height on 16inch rims but i plan on lowering it about 2 inches all around and i dont think my 4-1 2.5inch collector header will be to safe at that ride height so im wondering if any of you have ruined your header this way

 

I had a cheap 4-1 header when I first swapped and I smashed it only on large road debris. However, speed bumps were almost always a problem. So I ditched the header and went back to the stock cast iron exhaust manifold. I haven't really noticed a difference in power or my 1/4 mile times.
