I guess I've been under the "don't bother modding, no money" rock.. lol I just thought I saw on either some site or on here someone talking about SD Headers being around $600+ =P
I'd hate to replace my Downpipe already =P but if I did go the header route, I'd probably not cat it again. Living in Michigan and all, no need really to have a cat unless I have to go to a different state for a summer job or something =/
if I was to drop down to like a 3.5 or 3.4 pulley, do I need to do more exhaust mods? I thought you could get away with a 3.5 and a downpipe and not have to worry too much about too much else unless you were still getting knock? I mean I could be wrong, I am just going by memory of what I read after I got my GTP
