Would it be ok to have them installed before my tunes are ready or should I wait until after I get the tunes? Go ahead and get the exhaust installed. But make sure you put down truduals on your order sheet.
Also on the Gryphon order form should I put my current exhaust setup or the future setup? |
I see you are aware of the possible lean issue.
Run it on level 2 canned tow but don't rod the piss out of it.
You can do that after your custom tunes are done.
