A complete 4 into 2 system is about another $120. I was thinking that I'd just replace the mufflers for now, if I could. I hear that Mac's header fitment is always the greatest. Plus, I'd like to replace the whole thing with HM341 pipes one day, so I'm trying to spend as little as possible.
Now if I can just find a seller who would ship them to me by something other than UPS... bought a $100 chain from Dennis Kirk and ended up paying UPS a total of $80 for the privilege of having to bus out of town to pick it up, after they failed to deliver it, leave a note, or call me.
