    A:  You will gain more power with a custom tune, but in our experience we have found that tuning is not required for a crosspipe alone.

• Q: Tune? without will it cause damage?  Aaron Roth9 years ago

  I understand you have answered this question a few times already but I was curious as to if I do purchase this and install it will not tuning it cause any serve or minor damage? I wish to just upgrade from my OEM one to this but I have no plans on tuning for atleast another 5-7 months down the road. So can this cause any damage from not being tuned? Thank you RSD!

    A:  If you don't plan to tune for it your best option is to leave it off until you're ready. Mike
