I plan on doing the WMRC race school and any race/track days with my stock exhaust can on,
#1 If I go down, that's fine it's the stock can
#2 The stock will give me back my midrange and will be smoother...
Problem: at the last service BK opened up my pilot screws to mitigate the effect of the yosh. slip on so now worried if I go back to stock I might be running rich....would it matter for the short time the stock will be on ???
