I received a pair of two 2 1/2" glasspacks for x-mas and was goin to use them on my 4.6 swap.. I've decided to keep it original, it 2 1/2" gonna be too much for the exhaust? I was planning on also puttin on some dumps, so maybe if it is too much back pressure, I could "kick it out" and make some bends like DENVERDAVE here http://www.jalopyjournal.com/forum/showthread.php?t=152274 ? Or will 2 1/2" be ok, and should i make a twist off dump like TOMMY http://www.jalopyjournal.com/forum/showthread.php?t=152274 ?



All Help would be greatly appreciated ;-)
