It all bolted up nicely! It has *some clearance* like maybe 5/16" between the header and the pan. No worse than it was. Put everything back and she fired right off! Headers already look to have a new hue....
I now have a base line to start from which YOU S1 folks already had! What is nice is the ECM with the O2 sensor seems to remap and lean pretty quickly. But as said, now its ready for the real thing and either bite the bullet and ship the ECM or throw the fuel controller on it and call it good.
Did I mention that she NO longer sounds like a Singer Sewing Machine! This is much better! More in line with what I expect! She revs's, she pulls, she sounds like she means business!! 10K now sounds like the old 14K... And the response is good too! It was a short run, couldn't tell if that hurt the midrange or not?
S1 Header to S2 Bike! Notice bump in pan is gone. 2 Bro Y pipe and mufflers are ceramic coated black.
Phone SUCKS at pictures...
It can be done and its pretty straight forward. But to answer the question, no - gonna have to find your own welder!
