Hello Everyone,
Please let me know if I have this correct. As long as I don't change anything from the cats forward I don't need a custom tune when changing exhaust. I have been waiting to order my custom tunes, because I am planning on replacing the stock cat back with a SI/DO setup (probably a Magnaflow cat back system), but If I don't need a new tune when switching from stock to SI/DO cat back then I'm ready to order
.
Also Lars if you see this. What's up with the spark plug pictures?
Thanks,
Gary
