i have a B18c in my '94 Ls i already talked to a customer service rep from Skunk2 about which header to use. he said the gsr header and when i get the high flow cat welded on alittle custome work may need to be done as well. i was under the impression i would have to use a Ls header to fit up everything. so let the debate begin guys and if your pulling stuff out of your *ss dont post please. thanks guys![]()
