i have a 94 civic hatch with a gsr swap in it. i just bought a cat back for my car and was wondering what cat to run. right now i have a integra ls dc 4-1 and i had to get a peice of pipe welded up to make bolt to the civic exhaust. when this new exhuast gets here i wont have a cat or test pipe or anything, so obviously there is gonna be a gap between the end of the header and the starting of the catback. what cat can i use? am i just gonna have to get another peice of pipe welded up between them? any help would be greatly appreciated
thanks

 

test pipe

so i guess i will have to measure the gap and get one around that size??

 

up, i want to know too

 

 

i wouldnt exactly weld it in there, i would take it somewhere and have flanges made so you could put a cat on there to pass emissions
