I just received my 2 into 1 pipes- backlash from STG.My bike has finally made it to the dealer a few days ago to look into my high idle issue. I ran my pipes up to them. The tech said he thinks it may be an issue running my new exhaust without a tuner/ fuel commander. I still have stock intake. I was wondering if anyone has run 2 into 1 exhaust on a stock intake?
