Hey i was wondering if any of you hybrid civic 92-95 with b18c motor know the exact or close to exact gap between the stock gsr header and civic cat? a friend is currently using a b16 header stock and he wants to use the gsr comptech that my bro got but i know there will be a gap, let me know what you guys think
thanks

 

bump, come on guys,, lol

 

i have a 91 CRX w/ B18c1 GSR and i used the gsr header w/civic cat and crx thermal catback exhaust. There was about a 4in gap. I shoulda used the b16 headers

 

thanks for reply,
