the down pipe is longer on the one that is for my car and the one i have has a shorter down pipe so now i need to custome make a straight pipe to connect the header to the cat back exhaust would anyone know what the leangth of the straight pipe would be? has anyone done something like this befor? i had to do it in my old DA but i dont remember the mesurmants. please help

on the four door there is a mid pipe thats about six inches long and thats what makes up the difference in the pipe length from the two door to the four door

so you are saying that i need 6 inches of pipe to connect the header to the rest of the exhaust? i thought the DA exhaust was the same as a DB1 exhaust as far as leingth.

anyways this isnt a db1 or a da header so it runs short of the mid pipe.

come on, some one has to have more input

Come on!!! Put on the header, stop being a and take it to the muffler shop already...or...get the correct header
