There are two types of headers...ones that leak......and ones that are going to leak...
unless they're equal length tuned headers, and you plan on turning high RPMs, there is only very little gain in performance.....and adding mufflers kills most of that.
Years ago the first thing I did was to put headers on every vehicle I bought...now the first thing I do is take them off if it has them...
