Nice, did it involve recalibrating your Computer?
Yes, because if it does not require it to be tuned, it will only look and sound good, with little or no performance improvement. You did it right with the complete header and muffler, as opposed to just a muffler. Enjoy !!Yes it has to be tuned after. I’m waiting on the tuner with custom tunes to get here should have it Tuesday or Wednesday. I got 4 tunes total. 2 for tail riding 87-91 octane and 2 for mud and sand 87-91 octane
