So Im swaping in a b20 into my eg and the header I have is a bit short of the cat. Anyone know which header do I need to solve this problem??? BTW, its a stock LS header.

 

the exhaust shouldnt even bolt up assuming it is the stock d series cat?? the b series bolts are in a different location. as far as being to short no one ever said that doing an engine swap was a strait foward process. pull out the saws all and a welder and run down to vatozone to get some pipe and make it fit.

 

I've seen people use stock headers w/ stock d series cat and had no problem. Im use to DA's and DC's, this is my first civic.

 

hmm its always been an issue at my shop? maybe its just me but i can never get **** to line up right as far as exhaust goes.
